Hello,

I was wanting to see if someone could help me with my plants, I am growing them under a 400w hortilux on an ebb and flow table in 6x6 rockwool cubes. They were bunched up together (solved that problem) and I water them twice a day. thanks

More fresh air

have you ran your ebb/flow with rockwool before? it looks to me like they might be getting too much water. does the medium get a chance to dry out a bit before it soaks again?

What's the RH%, PH, Temps, airflow and nute levels (and which nutes)?

looks liek maybe too much N? maybe even some ph issues

temps around 70 Degrees, airflow should be good, i have a vent that brings in fresh air and a fan, ph, trying to keep around 5.2/5.8 range but it does fluctuate rapidly it seems, I can adjust it one day to a perfect ph, then the next day when I test it is way out of whack. I was using Advanced nutrients micro, grow, bloom with an assortment of other mad scientist additive, but switch to AN Iguana Juice and all organic additives and staying a little below the recommended schedule on the Advanced Nutrients Calculator from there website. I am suspecting that it may be due to PH. thanks for your help, and I appreciate any other recommendations.

Im with THC...That looks like overwatering to me. How many times are you watering per day and for what duration? 5, 15, or 30 minutes? My tables flood 4times per 12 hour cycle. Each feeding is 20 minutes. Once before lights come on, 2 in between and once again before lights go off. Thats just me and the thirsty strain i have likes it. I would recomend less for you untill see improvement.

Hey THC, good luck on POTM, awesome pic man!
