what's guys and fems lol having a little issue with my white widow fem seed grow, she's now in week 2 of veg and is starting to get black leaf tips and they are curling downward, need to know if anybody knows what exactly is wrong and what i can do to fix the issue. running my grow in FFOF, FF nutes , 250w CFL 650K, just to give some general info as well. room temp normally stays around 88F and falls to as low as 78F at night .
yes i have been adding nutes, but ok just flush and let it chill a few days no water or anything ? after that i just pick up where i left off as far as my nute schedule ?
