Yellow Leaf Tips

hey all you gurus out there let me pick your brains -


I am about four weeks into flowering and on most fronts the plants are fine. Green and healthy, thick stems and good buds.

But many of the tips of the leaves - the very very tips - are yellowing.

From what Ive read, this could mean two very different things. On the one hand, it could be a K deficiency. On the other hand, it could be over-fertilizing, with excess evaporation drying out the tips.

But I am inclined to think its the K deficiency, because it seems to me the drying out from over-nuting occurs around the entire leaf, whereas this yellowing is only happening at the very tips of the leaves. Otherwise, the plants are happy.

Any thoughts? (sorry no photo but not at home now)

Thanks!

you seem to have solved the prob yourself if it was a over nute prob then usualy it yellows right along the serated edge of the leave and not just the tip.i have seen it begin at the tip but if the tip has been like this longer than a few days its probibaly a k deficiency.hope this helps the postman.

Remember, leaves often fall off into late flowering aswell. If the leaves start yellowing and dying from the bottom up, then thats fine. If it starts all over the plant though, its probably a deficiency of some kind.
