Help, my leaves are turning yellow then almost white.the tips are then dying and curling up. the veins are staying greenish. but i cant see any other discoloring of the leaf, ie blue or purple. but the stems have the red coloring.
possibly iron, but im not to confident...

My guess is a sulfur deficency. With a iron deficency it starts at the other end of the leaves. Lower your ph to 5.5 to 6.0 and add sulfur to a fert with magnesium sulfate in it. (epsom salts) Deficencys occur when the ph is too high or when execessive calium is present!

Looks like nute burn on many leaves tips to me.
Possibly over nuted,maybe rooms temps are to cold during the lights of period.
Best of luck :weed:

Dsmn son!! That'd burn my ass!*s* I use Fox Farm, but I only feed every other watering. Go to the FF page and look at their feeding schedule, or search for feeding forums here. To add sulfur I use molasses.. it'll also aid in taste...yummy.
