Rifleman's Roost Open 24/7: Perpetually Perplexed

I should of added that I use dolomitic limestone powder in my compost. It adds cal and mag. Do not breath the stuff wear a mask. Its basically limestone dust and can give you a nasty nose bleed. ( And yes I learned that the hard way. Ha! Actually a couple of times, we hillbillies can be stubborn learners just ask Bride of Holler) Also I also occasionally add triple super phosphate to my pile about this time of year. It also takes time to breakdown and become available. Also phosphates are not very translocatable so by mixing it into my compost it is evenly distributed through my soil mix. If you want monster size colas outside during the season it is hard to beat triple super phosphate when back filling your hole. Again I stress low input cost production methods because I am a skin flint old farmer. I get 50 lb bags of triple super phosphate for around 27 bucks. Hey Lucas sorry to get windy here but you know me. Us country folk have a way of getting straight to the point in a round about way! As always, best of luck in all you grow!

First thing, Never feel bad or hesitant to post in The Roost. I might have started the thread, but it belongs to all of us. :) That goes for cannabis, monkeys, hot rods, or life observations. Off topic shit is especially welcome as it helps put deapth to the characters I know as Laz, Tead, UPH, etc. One can not grow if one does not seek out the differences in life. Nuff said, y'all post when and what you want here. :thumb:

UPH, I tried to grow tomatoes on my patio last year. First time in containers instead of the ground. Took me half the season to discover why I had blossom end rot. :biglaugh: I hammered them with calmag at every watering after that. Finally did get some real nice Cherokee Purples by the end of August. Started a rubbermaid tote of soil and kitchen waste in November, and have been adding all my egg shells and vegetable waste to it since. Maybe this year I can get by with just water. :)

Stay tuned folks. I'll be back later today with a few photos and comments documenting the next grow which started germination Friday. :Namaste:
 
Four beans down ! Two Short Stuff Auto Jedi Kush and two Sweet and Sour Devil's Crack. I'll be vegging them under the HPS at 600w. Nutrient feed is going to be starting at 1ml/L or 15ml Advanced Nutrients pH Perfect MGB and some Hydroguard. I'll start counting days and assign plant numbers when they break ground. :Namaste:






 
Do you start your 1ml/l feed when they break ground or do you give them a week or two of just water and hydroguard? Just curious. Im sure you've said before i am just being lazy, lol. And if'n you wouldnt mind, im going to put up a new pic or two of my situation later, so you can see and maybe give some advice. My girls are starting to worry me. Sigh

They are at 1ml/L right now as seeds with tiny tap roots. I'll top water until I get a rootlet into the solution. Then I will check pH, ppm again, and likely add some Voodoo Juice. I'll run that reservoir for 10 to 14 days past that. That's about as far as my plans go for now. I don't want to get too far ahead, it makes it difficult because I have too much time to wonder..."what if". :rofl:



Edit....feel free to post photos Laz. Hopefully one of the readers will have a solution for you. :)
 
If I were just switching to AN and we're still in the habit of checking pH this would drive me mad. With a couple dozen plants under my belt with AN it doesn't bother me as much anymore.

Here's what I'm talking about. 24hrs ago before adding any nutrients my tap water, which had been sitting in buckets for days, had a pH of 7.7 I added the recommended dose AN for seedlings, 1ml/L. After setting a while pH was 6.7 in all buckets. Today, 24 hrs later, buckets have been sitting with air being injected, no roots out of the rooter plug much less in the reservoir. Remember I just planted them yesterday. pH now reads 7.6 in each bucket at 75°F (yes 75, that's why I use hydroguard heavily). WTH? :rofl:

If you are new to dwc and using small reservoirs such as a 15L, do yourself a favor; Buy pH buffered nutrients, save your money on the pen, and forget you ever heard the term pH.

I am going to monitor pH for a few weeks, or until the plants make it a PITA. For no other reason than I'm curious. It's not going to change how I feed or grow, and I'm not going to adjust it at all. I'm just curious how much it actually swings with the AN.


 
Drive-by photo drop. Went up into the hills with another guest, a native Jamaican, to meet the man who's keeping him supplied. This was a cross he did of White Widow x Durbin Poison.

You grow circles around anyone down here Lucas. :battingeyelashes: :Love:

Correct me if I'm wrong, but wasn't Jamaican supposed to be really good pot? If I hadn't been treated to Doc Bud's personal stock of Tangie I'd be a little disappointed. As it is, I'm having a blast and a half.

Wish you were here. :hugs::hugs::hugs:
 
I've been having swings in ph down into the 4s. Its happened more than once now and i think it is causing my problems. It first happened at the end of my last grow and i thought maybe it was because the bottles were old and almost empty. But these are brand new bottles. I cant figure out what is causing the swing to be so great. Im not doing anything different than usual.

I will be interested in how much or little your pH swings. I use AN with distilled water and it almost always starts out around 5.8 when mixed up but creeps up every day. In just two days, in my gravity reservoir I have seen it jump up to seven. I rarely have to use pH up, always pH down, I will let it go to 6.5 then drop it back down to 5.5.
 
If my understanding is correct...and please correct me if Im way off base here...most nutes bring the pH down. If your pH is dropping in DWC that would mean that the plant is taking more water than nutes and the lower pH is a result of nute build up in the reservoir...ie. feed less. If the pH goes up, the plant is taking more nutes so add more to next feed? I know buffered nutes dont play by the same rules, so this question is just about unbuffered.

Just looking for the science here :)

Not sure if you can see it in the last pic but im getting some minor curling on the back edges of some of my sugar leaves. This spotting is all through the plants where the light hits the leaves. No brown spotting on underbrush.
I changed my rez on friday and the ph was 5.5. When i checked it last night it was 5.6. They have each drank 4 liters of water. Im going to check my ph and ppms a little later and see what its been up to during lights out.
Anyone have any ideas?
Update: just checked both my buckets... My ppms went up and my ph once again dropped to 4.4. Pretty sure the feeds that AN recommended when i contacted them is too damn hot. I added ph'd water and brought it back up to 5.5. That swing is insane. Im going back to 2ml/l next change out. Thinking about getting my money back from them just on the basis of their advice. Lol

Back when I was using Humboldt nutrients I had a similar thing happen but it was as they started to bloom. With my tap water the way it is I just added enough to bring pH up. I now have a chart in my blog the explains most of it.

AN strongly advised me not to adjust, just trust. When I have adjusted it simply rebounded back to where it was or slightly above. <shrug>

That's part of it Mouser when you're not using buffered nutrients. Water level, ec, pH, all have to be taken into consideration. With the buffered AN my best advice is just go with it. :biglaugh:


FYI, in my blog entries there is an entry with charts and photos for pest and problem diagnosing. Near the bottom of that entry is a chart that tells the different conditions in dwc and what to do in each situation. If you check and adjust pH it might be helpful.

Your photos look all too familiar Laz. Mainly the leaves that get the light, like they are working overtime huh? Let me ask...early on your roots were pearly white and glowing ? Now they are apparently stained brown from nutrients on top and more cream color below? If so we're paddling the same boat.

I'd say look at the blog entry I mentioned above, but it hasn't helped me. My guy at the local hydro store said he had the same problems I'm having with AN. He believes it is a buildup of salts during the grow. Since tomorrow is water change on the DD and I just happen to have some Z7 ...:) ...I'm going to treat them and see what happens. I never have been one to take another's word if something works or not, but y'all can trust me. :smokin: I'll let you know what I find out.

Going to stick my nose under the tent and say I think your plants are not getting Magnesium nor enough Phosphorus. It may be available, but they can't pull those two nutrients from the solution unless the PH is above 5.9, and from what you have detailed your PH is staying too low.

Many including myself advocate a gradual PH swing weekly from 6.2 down to 5.6, the reason being the plants need both ends of the PH range to be able to properly absorb different critical nutrients. A helpful way to view the PH thing is they need to hit both those readings at least every week to get a balanced diet.

At this point it's probably not recoverable as far as the spots go, but it's probably not going to hurt your results because you're almost done and if you get the reservoir up to 6.2-6.3 for a day your plants will pick up the P and Mg they need and be okay growth wise.

Buds looking frosty. Keep it up.

Peace, Hyena
 
Nutrient company's feed charts are based on a healthy 1000w garden. A week one seedling may demand 75ppm under 1000w (just an example, never use a 1000w on a seedling) That same seeding under a 600w would be 50ppm, 400w is 25ppm. All nutrients are pretty much the same and all work if properly used. On the periodic table, there's only one symbol for Nitrogen. So most deficiencies are usually micro related unless you are leaving a part of the 2 or 3 part nutrient out. Reservoir water temps can alter pH greatly. Warmer room temps make a plant drink more to cool, which a regular person keeps topping up the water level, mixing in fresh nutes, causing too many nutrients. Salt keeps building up. Not allowing the plant to take up what it needs into its vascular structure. As long as you keep your Ph between 5 and 7,
"pH and Nutrient lockout " are mostly just caused by too many nutrients and over watering.

Thanks gents. I have recently purchased Z7 to try out and i think I'm going to flush the medium with it and give them fresh nutes at a lower concentration.
Rifleman, my roots were pearly white and have faded to cream colored but i used Z7 on my lest rez changebon friday and my roots are getting pearly white again. Time will tell but so far it seems like its doing what it said it would.

I'm glad to hear that about the roots and z7 Laz. I'm working on a theory and having my plants spread out in development is going to help in figuring it out.

Tomorrow ends week ten since sprouting. It snuck up on me. :) DD4 will be switched from Big Bud to Overdrive. Due to the water change not happening until the afternoon I'll have some extra time in the morning to use the tripod and attempt some macro shots of the trichomes. With 90% of the pistils turned I'm sure harvest is close. :) Y'all check back after brunch and we'll see what I can come up with. :bongrip:
