I unfortunately cannot grow all those awesome strains you guys can get but by luck we have aquired some really fun things to grow.
(this is the only thing I have no Idea even as to what your talking about,I wont mind if you tell me either.)Well it appears as though I'm still having issues. I'm super bummed. The upper canopy growth seems to have improved since I flushed everything, but I'm still losing lower leaves at an alarming rate. I'm 2 weeks into flower now and stretch is slowing and healthy bud growth has begun. New leaf growth is still a little "neon green" but these leaves do appear to be darkening quicker than before. The pictures included below are all leaves that came off the plant today right before I watered. I'm very concerned that the rate of lower leaf drop I'm seeing will have a substantial impact on yield.
Here is a breakdown of what I've done in an attempt to solve the problem:
So I'm still having issues. Here are the remaining suspicions I have:
- Flushed each 2 gallon Air-Pot with 6 gallons of water. Runoff pH to 6.5. (0 days passed)
- Waited for soil to dry partially, Fed with 3ml PBP Grow, 10ml PBP Bloom, 5ml Liquid Karma, pH to 6.5 (3 days passed)
- Treated with Spinosad for small thrip issue (3 days passed)
- Thrip treatment successful, no moving thrips visible (5 days passed)
- Waited for soil to dry fully, fed with 5ml PBP Grow, 15ml PBP Bloom, 2.5ml Silica Blast, pH to 6.5 (6 days passed)
Looking forward to hearing your opinions. I've been very careful with this grow and I'm quickly losing confidence so your help is much appreciated!
- I am underfeeding
- I have bad water
- Plants are rootbound in 2 gallon airpots and thusly can't sustain lower leaf growth
- Pots drying out too quickly
- Lower leaves not receiving enough light through thick scrog canopy
- I didn't flush enough
- I'm experiencing tent off-gassing (seriously hope not)
..[1]I am underfeeding, (Maybe? but not your fault,PH of run off?)
PH run off was 6.4
[2]I have bad water (boil it then its good again,maybe twice)
I may give this a shot before I think about investing in RO.
[3]Plants are rootbound in 2 gallon airpots and thusly can't sustain lower leaf growth (try and see if this is the case,I doubt it though)
I doubt this as well, but it's pretty easy to check with the airpots so I will take a look tonight.
[4]Pots drying out too quickly (Water more often)
hehe
[5]Lower leaves not receiving enough light through thick scrog canopy
(If you are scroging this is probably most definitely the case,and to be honest I wouldn't worry to much,if you look at my DWC grow,I removed the bottom leaves myself because they were only restricting air and doing nothing else, If they cannot recieve light,what is thier purpose anyways, Scrog as far as Im concerned you are supposed to focus on the canopy,I would trim the "Trash" and focus on the flowers.)
Well I can say all the leaves that are dying are definitely not receiving any direct light. The canopy is very thick as my growing space is only 2x4 so I'm packing it in tight. No direct light gets down there in the abyss. I did not think the leaves not receiving light would cause them to die like this. Am I wrong with that assumption? Why I'm concerned about these dying leaves is that I'm still losing useful energy the plant could be using. Every time I see a leaf drop I think to myself that is that much less power going into the buds.
[6] I didn't flush enough]
(if the water ran clear your good for flushing)
[7] I'm experiencing tent off-gassing (seriously hope not),,
Some of the grow tents are lined with materials that give off toxic gases that make their way into the plants. I thought I bought the right kind of tent with the silver non-pvc lining, but maybe even some of those are bad. The pictures I've seen of off-gassing look similar to my plant. There is a big thread stickied in the forum. I am going to post there to see if I can get some opinions.
Just my thoughts,Use it dont use it,
I wish you all the luck because it sounds as if all your time and effort feels like its going to waste,I know the feeling.
Namaste!!
wow, im really surprised at how many growers recently have hit this wall. Even some experienced growers i know are having trouble dealing with it. you need to get back on track asap.
1. You've identified Thrips as a pest and used spinosad to treat.(thumbs up)
Word, felt pretty good about that!
2. Everyone's first reaction here is adjust pH and flush. Personally, with all the cases recently, i think the problem goes alot further than this.
I've been pretty careful with nutes and I've tried 2 different brands now with the exact same results. Unless my buffered ph pen is way off I also feel pretty confident in how I've been managing ph. I have some strips I'll use to verify.
3. Something in your water ? very well could be, some cases of pythium are popping up around at this time. I tried saving the file to zoom in but it was all blurry on my screen(water quality info). If you have access to RO water, use this for your flush.
I don't have access to RO water and with the failure rate I'm experiencing at this point I'm hesitant to invest in $300+ pieces of equipment.
4. Your tent isn't the only source of out gassing. Many products in found in and around our homes are made of materials that will out gas. I see your scrog net has some type of frame to it. Is this made of PVC pipe ? If so, it must be removed immediately.
The tent is indeed made of PVC pipe although I was under the impression it was only soft PVC tubing and liners that were causing problems athough it would make sense because PVC is, well, PVC I guess?
Keep us updated because if you beat the problem its better than giving up. It wont be easy to identify and fix this problem, but hang in there, dont stress we will figure something out
I will definitely keep you updated. I'm definitely frustrated, but not ready to give up yet. Thanks for your thoughts!
