Hi 1st time grower here. Using Tupur Royal Gold, General Hydroponics nutes at ppm 400 and 6.2 PH. I noticed that the new growth appears to be kinda lighter ( more yellow) and my 1st set of leaves are twisting on one. I am running a SF4000 at 20 inches at about 15%<90watts (turned it up to 115watts yesterday(²⁰%) and when I got home noticed that my leaf edges were curling upward slightly so turn it back down.
Deficiencies or paranoia
