Happy to try and help but I need some info:
1. Strain
2. medium
3. fertilizer ppm and pH
4. temps and humidity
5. watering how often and how much
And anything else you can think of. The more you give me, the better suggestions I'll have. I'll help you up to a point, but this appears to be a big operation and your best bet is bringing someone in quickly to advise you before you lose the crop.
But know, these LED's push plants hard, so if you're not dialed in, issues will be more pronounced. I'm thinking you probably have the same issues under the other lights, just milder at this point.
So you started with 18 Gavita's??????? OK then. LOL I'm restraining myself from saying anything negative.
1. Promix1. You mean just regular dirt? As in soil, or soiless soil like pro mix?
2. I don't know the strain, is it indica/sativa/hybrid?
3. How old are they?
4. Did you get the clones in rockwool cubes or dirt or whatever?
5. So you watered 3x in 5 days?????
6. When did you first spot issues?
If I have to play 50 questions, you're plants will be dead by the time I understand everything and can help. Is this your first crop, how long have you been growing, have you had success before, etc., etc.
I’ll post some close ups tomorrowI'll need some close up pic's, the leaf clawing is usually caused by over watering. It could be many thing right now, including insects.
Thanks for the input man. Just stopped the co2. I didn’t think it was the LED but that’s really the only difference between the two rooms other than the type of AC unit. Will raise the pH to 6.3. Using aptus nutrients. Water source is Well water run through RO. Did not add CalMag to buffer because research I did on the forum the nutes said the Aptus massboost basically replaces the need for CalMag. Got any thoughts on that?First off, it's not the LED's, especially if you are runninng them at 55%....... get that out of your head. No doubt you are in trouble, and if it was me- I would ditch the grow and start over. But lets assume you want to push forward with the hopes of things improving. One thing you'll learn over time is once a grow has issues, yield tends to suffer in the end. I just chucked a whole room of 24 seedlings because I didn't like the way they looked and had no vigor- sometimes it's best to just move on.
When you transplant and introduce new things, plants need time to adjust to their new situation. They are stressed, and showing some ill affects. I've run Pro-Mix everywhere between 6.1-6.5 and 6.3 is ideal I believe so raise the pH up. Stop the co2, until they are healthy- you are pushing them which is making thing worse.
Post some closeups, let me take a look at the leaves and we'll go from there. Also, what kind of fertilizer are you using and are you adding Cal/Mag? Also, what's your water source?
This guy is having plant problems........ you don't want to push these sick plants with high intensity until they recover some.
Also, regarding that chart- is that with or without co2? I run lower than the humidity stated, as I'd
Its a vpd chart. Doesnt matter about co2.This guy is having plant problems........ you don't want to push these sick plants with high intensity until they recover some.
Also, regarding that chart- is that with or without co2? I run lower than the humidity stated, as I'd worry about mold and droop. I generally won't run above 60%.........
Only way you get mold is if your humidity swing from day to night is more than 5%. As long as you can control your humidity spike your good. No mold.
Leds are not intensive by the way. Hid lights are.
An nowhere on this thread states to check runoff? Hmm how are you supposed to diagnose a sick plant without reading runoff?
Absolutely agree with @sshz you do NOT want to blast sick or struggling plants with light.... it will only make them worse.If your leds are 3ft away u should be cranked up to 100%. Strains that are not used to leds tend get used to intesity which leds have none of. Also read your runoff. Maybe they just need a good flush.
