Spectrum king 400+ FoxFarms Ocean Forest RO DI water 0tds, 0ec, 5.9ph RH is 50to84% 65to75*F Blueberry F2 I just lowered the light from 36" to 12" and reduced 2hrs to 15/9. Reduced my fan from high to low. 1st plant is doing great snd had a nice 2" growth spurt in 2 days. Has leaves twisting sideways. 2nd plant is doing so so. The 3rd is still kinda struggling. At first I thought nitrogen toxicity as the plants were dark green. Then lower leaves died, next all the leaves curled like tacos.
Bummer about #3, good luck on the rest your grow op dude. Sent from my iPhone using Grasscity Forum mobile app
FFOF is seriously hot..then you make it hotter by adding even more nutes ...(OK) flush with 3 times the volume oif the bag add 30% more perlite no nutes until you see some action even then 50% less good luck
I was using good robwater untill today. I just mixed up a weak batch of botanicare nutes. Yesterday I reduced 1 light to 10". Added two more fans so they blow heat off the lights. Added a circulation fan. Canopy temps are a stable 70*F day and night. It looks like they're asking for more nitrogen & phosphorus right now. Do you agree?

Deffinately light bleaching starting to happen. Bumped lights up to 13.5" inches. Moved a wall fan down and center just for the lights. Now my top canopy temp is 68* and lower leaves are 66* ac target temp.
