KJ's T5/CFL 1st Time Grow

I've turned off the fan, I'm going to put any plants affected downwind and away from the others. A local shop said that I probably have two problems:

1. Wind burn from the fan and that's unlikely to recover.
2. Powdery Mildew or spider mites as their eggs are white and on top of the leaf - news to me about the white on top of the leafs

I just today noticed one plant with white flakes on the top of the leaves. I don't know what it is, but it wipes off.

I'll get some pics of that soon.

The guy at the shop said to use something called 'Green Clean' and mist it over the plants. He says it's ok this close to harvest.

Right now, the fan is off, the a/c is on and I need soil so I'm going to talk to a few local shops and see what they say.

There is one other note, my home is concrete block and part of the remodel involved busting up some concrete. There as a 'cloud' a few times and it was the room next to the grow room. The walls are there, but not air-tight. This might have been some concrete dust, but the white flakes are new and the dust clouds were last weekend.

Again, I'll post some pics soon.

Karl, are you using a cool mist humidifier? I get the white flakes as a result of the minerals in the water forming as the airborne water vapor evaporates and the minerals precipitate in the air and get blown around by the fan...this phenomina ( spelling ) is harmless. IDK if i've ever seen windburn, I use fans bro, i like my plants to be moving all the time, as long as its not blowing on em continuously like a friggen wind storm, I seriously doubt the windburn theory. I do know that the dust bunnies that form on the fans will cause problems...another vote for cleanliness, and periodic cleaning is absolutely necessary. Just some ideas karl, the answer is right in front of us always, we just gotta go throught he process of elimination, kick out anything that goes against the fundamentals and drive on!
 
The humidifier is a swamp cooler, but that's the same thing as a cool mist type. They just flow water over something that evaporates water into the air.

The white flakes were dusty when I touched one of them. Also, the 2nd grow endup up with PM as well. One plant had it exactly as in the pictures you'd see when you look up PM.

As far as the wind burn goes, that's just a guess. I talked to a few local growers and that's what we came up with, mainly because the ONLY damage was directly in front of the fan. I really don't know what else would affect just those site and no others on the same plant.

Although the RH was about 30, directly in front of the fan, which is directly in front of the A/C, the RH at that point would have been lower than the 30. The 30 RH was measured at the top of the cabinet. So it was pretty dry fast air and only seemed to effect the hairs and leaf stems, which I understand are a bit weaker.

Again, just guessing, but it does seem to be under control and there is regrowth where the damage is.

If anyone has any other guesses, please post them. It would be nice to know for sure what actually happened. However, I am glad it didn't get worse!

Cool mist differs in the fact that the water is drawn up through a series of baffle like passages ( very broad explanation)and is spun at high speeds in a manner that renders it in a mistlike configuration that is actually visible, an evaporative cooling system works on the principal that as water evaporates it effectually becomes cooler. My experience with this type of humidifier comes with my experience with aircraft humidifiers, They have units that can put 2 gallons of water vapor in the air in a matter of a coupla minutes. This is required as the air at high altitudes has little to no humidity, these aircraft fly at those altitudes primarily and the aircrafts equipments lifespan is prolonged dramatically, as well as the health and comfort of the passengers is increased. This type of humidifier always emits a visible vapor, in the case of a large aircraft such as air force one...LOL....the humidifiers put out a vapor that looks like a smoke machine. I have assisted many times with this type of unit.
 
Didn't know that. I had a unit that I burned up the motor on, I ran it till it burned up. I really didn't know how it worked, I guessed it was just a 'mini' swamp cooler. Your explanation makes more sense, it did have passages in it.

I know what your talking about with the water spots. I had those water spots a few weeks ago, freaked me out at 1st.

I can get 4 humidifiers at the thrift store for 10 bucks, I fix em a little ( no filters on the evap ones and the thing that depresses the valve on the res is missing sometimes ) and use em til they die....LOL.
 
Looks great KJ!

Those trics are coming along nicely!
Thanks!

Update: Moved the lights apart by about 10" to allow me to spread the plants out more.

Watered with nutes (Moved to the mix that doesen't use FloraGro any more and doubles the FloraBloom) and the new GH Kool Bloom. It's supposed to boost the blooming process. We'll see how well the buds fatten up!

That watering pump is AWESOME! No way I was going to get in there the old way without damaging the plant.

I think the watering wand is made for higher pressure, I might remove the selector tip and see if the flow kicks up.

Sprayed for PM once again. This time all the plants got sprayed. I also sprayed inside the unused closet, I guess the wood can carry PM. Once this grow is done, the room gets a full cleaning.

RH is in the 30s so I hope I'm in the clear.

Lights are setup for the 2nd grow, they all seem to have taken to the new grow bags without problems. The new adjustable light hanging system works awesome, VERY flexible, already had to adjust the light positions for more even lighting. Some of the plants are getting bent by the fans even on low speed. I need to get a few ceiling mounted fans soon.

The growth doesn't seem to be on par with the 1st grow. I think the CO2 from the furnace made a difference.
 
Update: I've treated twice with Activnotate. I found what looks like an outbreak on one site and a few white dots in other areas. The white dots are unknown because I get those all over the house, probably due to the remodel.

However, the one site looks like PM.

I picked up some Serenade and I'm going to treat them again. The last treatment was Monday and I noticed a number of yellow leaves, generally older leaves and all fan leaves. I understand this is normal as the plant gets close to harvest time, and the one with the most yellow leaves also has the most trichs.

The Serenade says it can be used up to the day of harvest, so I'm going to give it a try. I don't know if I missed the one branch or what, but I'm going to give this stuff a try.

Other than the PM issue, the plants look good and the buds just keep getting thicker. They are clearly going to finish at different times, the taller ones are actually behind the shorter ones in terms of trichs.

I'll post some pics later.

My plants are like that aswell my 3ft plant barely has any yet mostly in past two days but my smallest 11 inch plant thats struggled its whole life for unknown reasons is covered with trichs.

Goodluck fighting that pm I hope the treatment works.

Thanks! If nothing else, at least I seem to be keeping it under control. The 2nd grow has one plant that looks like it need another treatment, but it's hard to see where it's at, I'll have to pull it out for a closer look.

One problem is that the treatment leaves a residue on the leaves and it's hard to tell if what I'm looking at is residue or new PM. I might be over reacting, but with an organic treatment, it's shouldn't do any harm.

Do you have leaves that are turning yellow and falling off? I'm nearly 5 weeks into flowering, so probably 2.5 weeks or so from harvest. I thought I read where leaves dying off was normal as the buds thicken and mature.
 
Not really im around 45-50 days into flower and besides what i think was heat burn ive only had a hadfull of dead leaves and pretty much no yellowing at all Yet. But alll cloudy trichhs on my shorty(lleaves have been yellow and brown from seedling?) and my middle plant too But still no yellowing.

Maybe the PM treatments were too much for some of the leaves. IDK. The buds look healthy, so maybe I'm ok.

you didnt need thos leave anyways ; p they were just blocking ur bud's light ; P
 
have a question about the days of flower you guys discuss - do you count from when you first notice flowers? or is this days in 12/12 lighting setup? I am trying to figure out when mine will be finishing and establishing a little work-calendar for myself - figuring when i should be stopping with feeding and just flushing them out, prepping for harvest. they are growing well and it's my first time so really excited to see it finish well!

So days since flowers appeared? or days in 12/12?

thanks guys!

thanks guys!

Some count one way, some the other, it's kinda tricky given the number of variables present. When you're working with one strain, grown it a few times, you get to know it and can become very accurate estimating timing. Off the cuff, I time em when I flip, and it usually takes a little longer. The main idea is this, let the plants tell you when it's time, this way you're sure to nail it. We'll help you to decide.....you decide.

try to start counting when you switch lights over, im veging right now and they are starting to show flowers because im tapering there daylight back, normal plants take anywhere from 65-90 days common to finish around 70 days. you want to start to stop feeding about 2 weeks before and only use certain nutes to help them finish or flush out better.
 
I was talking about from when I switched to 12/12. I think it was about 1 week or maybe 10 days before I noticed the hairs. I'd have to go back and check the pictures to be sure.

This is an interesting point. I'm _GUESSING_ that once I start to see a certain amount of amber trichs I was thinking that would be about the right time to start the process. I don't know if you can just say "X weeks" from flowering. My clones didn't show anything but nubes after 1 week, then about 10 days they had huge roots... Others seemed to have nice roots showing after 1 week.

My point is that I think it's more up to the plant than anything else. It goes thru it's process on it's timeline. All the plants in my 1st grow were treated the same. Yet some are MUCH more 'frosty' than others. Some buds are looking MUCH further along than others.

The taller ones seem to be behind by about a week or so.

If I just went by the 'number of weeks', I'd harvest all on the same day. I don't think there is any chance of all these plants being harvested on the same day.

I think the bigger/better question is how do you guess when it's 1 week away? If you see 60% amber? 70%? Is it better to start flushing early?

We're trying to get the nutes out of the buds, and then reduce the amount of water a bit to shorten the drying time, but if you miss by 2 days, does that really matter?

IDK.

I understand at the point of harvest, the plant is entering or has entered the 'dying process' So if you stop the nutes (start flushing) 3 days too soon, would that matter?

Maybe someone has better info and can chime in.

My guess is when you see about 30~40% amber, you'd have about a week left. Assuming you want 80+% amber. Maybe watch on a day by day basis and see how fast they are going amber?
 
I feel you on that and hopfully someone more experianced in flower can jump on thos questions because i would inquire to know about that.

I think it is more about, "Hey i want to cut you down in 2 weeks, you only get water now woman!" :surf:

2 weeks? ok, that makes it more of a problem to predict. I'm probably close to 2 weeks now! I was just about to add some more nutes with my new 'bloom' helper.

So what's the downside of adding nutes too late. Is it just flavor or is there danger involved or more/less yield?

My understanding is that if you miss time the clear water, you just have a longer cure/dry out time, but no damage.
