browning of the tips is usually heat stress. move your lights a bit further away and add a fan so its got constent air circulation.

Nute burn usualy starts on the edges of the leafs.

So I am doing an indoor grow, my growlog is in my sig, but to bring everyone up to speed here is where im at: 2 girls, lowryders, day 30, both have been looking really really good so far. im feeding with watered mixed with pure blend pro bloom for soil. and i am also using a bit of molasses. pH of my water is around 6.6 or so. temps are at 78°F, humidity at 40-50%. For a little while ive noticed a few leafs starting to brown just at the very tip of the leaf. the Rating: 5
