they look underfed. What are you feeding them with? I will help you if you respond.
Running floraflex as nutrients. I have them WAY down on ec and ppm currently because i was batting root issues and possible lockout. The new leaves look very well and growth has restarted.
As advised by a few others on this thread i have gonae to using pool shock to run a sterile system and that has cleared the root issues and smell completely (its wasnt ever THAT bad, so it was caught earlyish). When i was feeding at 1.4 ec plants were stunted and not eating or drinking. Dropped to .6 ec plants leached raising ec. Dropped to .4 and plants are drinking light amounts of water and have rose ec by .02 over the last 2 days. Ph is rising frlm 5.8-6.1 over a 24 hr peroid. It has never dropped below 5.7 nor been above 6.2
Water temps are consistant at 67° rooms temps i am boosting at lights on today to 82° as im running LEDS and im suspiciouse my Leaf surface temps are not htting what they should be (buying ir gun tomorrow). Temps before were 78° lights on and 68-70° lights of. RH is 65%.
Room is 400 sq ft, 6 oscillating fans with none blowing direct onto plants. Lights are now 4.5 ft above plants running at 60%.
