This is my first round with some OG Kush. I am only veging now but want to flower soon. They have started looking a little funky. Can anybody tell me whats going on here? Plants are almost 3' tall in 3gal pots. I am growing in coco/perlite in a sealed room under a 400w hps. AC is on at 74 degrees. Its about 60% humidity. Im watering every couple days or so at about 800ppm using RO water, 200ppm calmag, 100ppm liquid karma, 500ppm fox farm grow big. Ph of nutrients is 5.8-6.0. Runoff has started coming out around 5.3 ph. No Co2 yet but its coming soon. I had spidermites a little but killed them with a fogger. Please Help.
Nutrient uptake of P and Mg is locked out. Run-off PH should be 5.6 to 5.8 and make sure Mn is in the mix.
I flushed with at least 12 gallons and I can't get it above 5.5. I even tried flushing with some 350ppm solution at 6.9 towards the end and the runoff actually went back down to 5.3. It's only in a 3 gal pot. I can't figure it out. I checked my meter and everything. I guess I will try again tomorrow.
whats ur ph supposed to be for a 50% coco & 50% promix hp with worm castings & cow manure..What should the ph water going in & coming out thanks
