1st Grow: Jumping Into The Deep End, DWC

They will start to slow down drinking near the end - you could reduce the nutrients at that point, or just decide to do it about a week before harvest.

@FelipeBlu Fantastic information. I will watch the water consumption for clues to reduce the nutrients.
FelipeBlu said:
Yes, the pH will fall if the plants are consuming more cations (K, Ca, and Mg) than anions (NO3, P, and S). At this point, they are probably eating a lot of K.

No need to flush. Studies have shown that it isn’t possible to remove nutrients from the flowers. Just look in @InTheShed ’s signature.

When you say no need to flush, so you mean there is no need to use the Flawless Finish 24 hours before harvest to as I described above? Should I skip that and just continue with nutrients until the chop? I understand that flushing for weeks to clear nutrients from the flowers is a flawed concept, but thought for hydro there would be some benefit to flushing the roots 24 hours prior to chop.

You’re doing very well - there’s just a few things to learn when you start lol

Thanks again for all of your help. I just started growing in September, and researched quite a bit before starting a DWC grow. I joined several forums. At this point, this is the only forum I go to. Unlike most other forums I have seen, this place is filled with kind and thoughtful people that are just trying to grow their medicine and help others do the same. I hope to one day be able to pay it back by helping others the way you guys have help me.:yummy:

Flower tent week of 12/7


Well, I added Epsom salt to Demeter and Alice, and they were still getting worse. So, everyone got a bucket change with the 4-4-4 recommended nutrients. I learned from this that I do not know enough yet to start creating a custom nutrient blend. Thanks to the members of this site and FelipeBlu, at least I have a better idea of what I need to learn before attempting it in the future. For this grow, however, I just went back to 4-4-4.

As soon as they invent a way to get that across the internet, this forum is gonna have to upgrade some servers. In the mean time, those pics do an awesome job to bridge the gap :yummy:

@PlanetJ if you get smell-a-vision, then you need to get smoke-a-vision. Then we can get this party started!:passitleft:

Temps 12/13

With the weather turning cooler (mostly), I am keeping the daytime temperatures at 75 with night temperatures down to 66. Humidity is staying in the 40s, except for a incident on Saturday. I went down to the basement to mix some nutes, and started filling my 20gal water tank. Well, I forgot about the tank and went back upstairs. A couple of minutes later, I hear a siren and my phone starts going crazy with alerts. It was my Govee water alarm.

I have two in the basement; one in the tent with DWC, and one under the sink/water tank. They definitely paid for themselves this weekend. I ran downstairs and turned off the water, and then cleaned up the spill. Without the alarm, though, the water could have been running for hours. The spill bumped up the humidity in the basement for a few hours, but then dried out.

I took a bunch of pictures last night, including some trichrome shots. I have a little microscope that attaches to my phone. Boy, those things are hard to use. Or my hands are not steady at all. Both? I took about fifty shots, and the 5 decent ones are below. It looks like I am getting some amber on the sugar leaves, but still mostly clear on the buds. I will try to get some better shots tonight of each plant.

Alice and Demeter, the white widows, are showing their Mg deficiency. Neither are getting any worse at this point so I am hoping they finish off strong. Kini ended up way to crowded/bushy. She has some good buds, but everything is packed in there together. Lorraine has the prettiest buds, and had the biggest stretch.

This last two weeks seem like the longest. There is less visible progress on a day-to-day basis. Sure, I can see the buds getting bigger and fatter, but it seems to be going SO SLOW. I feel like a little kid the week before Christmas :) Just a little longer...

It looks like this grow is coming into the final stretch. I switched to 12/12 on Oct 22nd (10/22), 8 weeks ago this Friday. I am starting to see more orange hairs on the buds, the smell is increasing, and it looks like I am getting more color in the trichomes.

Being my first grow, I have some questions I was hoping someone could help me with:

- At what point can I start cleaning up fan leaves? I would like to get more light to the lower buds, especially in the week or two. Does it make sense to start cleaning up some fan leaves now? Should I wait to remove any fan leaves until harvest?

- How low should I try to get the humidity? I have been lowering as I go through flower, and am currently down to 40%. Should I try to go down to 35% for the last week or two? Lower?

- About 24 hours before harvest, I am planning to flush the roots with AN Flawless Finish. I will mix up a bucket pH'ed flawless finish then pour through the hydroton to attempt to flush as many mineral salts out of the substrate and the roots. I will let the plant sit in the flawless finish for about 4 hours, then do the same thing with plain pHed water. 18 or so hours later, I will harvest. Is this needed? Will this do any harm?

- And, of course, any idea on how much longer I have? 420 says the Hindu Kush flowers for 7-8 weeks, and the White Widow for 8-9 weeks. For these strains, I am hoping to harvest:
- White Widow (60% Indica, 40% Sativa) - I am hoping for this to be a good daytime high, known for inspiring creative bursts of energy and euphoric open-mindedness. I think I am looking to harvest at as close to 100% cloudy as I can.
- Hindu Kush (100% Indica) - This is to be used mostly for insomnia and pain management. My wife, mother, father, father-on-law, and mother-in-law all take edibles to relieve pain and aid with sleep. I think that a little more on the amber side will help with that, but am not really sure. I have also read that if you are growing mostly Indica hybrids, it is better to harvest your plants when the resin glands are completely developed but not fully ripen - before they turn amber - unless you want to be glued to your sofa.

Any guidance on what I should be concentrating on to determine when to harvest? Any guesses as to how much longer on these ladies?

Good day @LKABudMan beautiful ladies.
Hope you are well today my friend.
I'd say could be up to 2 weeks as a guess. :Namaste:
See all those white pistols they have to turn red and crinkle in before she is finished flowering and building for you.
Once they have turned red then you go by your tric's.
Clear / Cloudy energetic feeling.
Cloudy / Amber relaxed feeling.
Keep an eye on the pistols, when you get closer we can help.

Stay safe
Bill
 
Thanks @Bill284 That sounds good, I look forward to two more weeks of buds swelling! Do you think I should clean out some of the fan leaves? I think I have good airflow in the tent, but am still worried that the middle of these plants are too bushy. Should I remove some fans, or wait until harvest?

I would leave them :passitleft:
 
Thanks @FelipeBlu for all of your help on this grow. I have seen so many pictures of plants at the end with no fan leaves, I thought it was helpful to remove them to let the buds get more light. I will keep them on, though, through the end of the grow. Man, these last few weeks of my first grow really shows that time is relative ;)

Happy Growing.

I'm not a fan of plucking fans,hehe. :rofl:
Sorry couldn't resist.
I'm a firm believer that they need them to build buds.
Fans do photosynthesis not buds.
Make sure you have good air circulation.
Try and drop rh below 60 if possible and feed them till the end.
Just let them be and they will reward you. :love:

Stay safe

Thanks guys. OK, I think I get it now. I need to STOP trying to mess with the plants and let them finish. I have the humidity in the 40s and I have good airflow in the tent. Now is the time to be patient. Even though I really hate patience sometimes ;) I hated it when homebrewing and I hate it now. However, I have found that patience is usually rewarded :) So I will be patient.:meditate:

Temps week of 12/17

It has gotten unseasonably warm outside in the last couple of days but that will change in the next day or so. You can see where I went down at 6am this morning and opened the screen door in the basement to cool it down a couple of degrees. The humidity has stayed in the 40s so I don't see any issues.

Lorraine is still my star. I am not sure why, but since the stretch she has grown more than the others. It may be because she was LSTed and defoliated the most and she has better airflow. It seemed early on that Kini, the other Hindu Kush, was growing faster and bigger than all the others. Through the stretch, though, Lorraine really took off and Kini not so much. I think Kini just has too many buds in a small space and was not quite defoliated enough. Other than airflow, everything else has been as even as I can make it. Both of the kushs are looking green and healthy and drinking 2-3L a day. Kini seems to be a bit further along with more orange hairs. Lorraine is still all white and putting on weight.

The White Widows look to be struggling. I went back to the 4-4-4 AN pH perfect, but it looks like they are still having problems. Both are only drinking about 1-1.5L per day. Alice is worse right now but Demeter is right behind her. I am not sure what to do about it, though, and not sure how much it matters this late in the game. Both are due for bucket changes this weekend, and I plan on cutting the nutes down to 50%.

Happy Growing.
 
Hmm I'm not certain. I'd give them that fresh reservoir soon as you can if your having uptake issues. You can also pour some RO water over the roots to give them a rinse.

What's your cal mag feeding level? (Do you know it in PPM roughly?)

I will say- that photo of all 4 looks sweet buddy!
 
Thanks @Rexer right now they are all on the AN schedule, with no additional cal-mag. I tried to change the AN from 4-4-4 to 4-1-4 (reduce grow), and that seems to be what started the issue (Mg def?). I went back to 4-4-4 hoping it would correct the issue. It may have helped, but the issue is still progressing. Not sure if I need cal-mag (mine has N), or jsut Epsom salts. Here is Alice's nutrient schedule through week 8 of flower.

I plan to mix up both Alice and Demeter a fresh bucket today or tomorrow. I was hoping to get some feedback first, though.

I agree that the tent picture is a thing of beauty. I open up my Wyze app just to gaze at them frequently :) For my first grow I am super excited just to be harvesting four plants. Sure, there are a lot of things I would do differently, but I have really enjoyed the process.

Happy Growing.

Both are due for bucket changes this weekend, and I plan on cutting the nutes down to 50%.

I think I remember reading somewhere that WWs are heavy feeders - and yours do look hungry. I wouldn’t cut their dose by 50% unless you are within a week of harvest.

What's the NPK of your cal mag? I think if it's not high crazy high in N, it may be just what's needed.

For your first grow, they're spectacular!

Yeah me too, heavy on the cal mag from what I've read. And I remember the one time I grew one I kept getting mg deficiencies. What's your thoughts on some cal mag?
