Things are moving along nicely. Only issue is some yellow tipping so moved the lights up to 21" still at 80% power. I thought maybe nut burn?? Noticing there is ALOT of cannabis troubleshooting tips available but overall plants look great so moved the light bit. Alternating between plain tap water and the Fox Farm nutritions. Did LST during week 3 and 4 and now plants are really taking shape!
