HEy all, been having this problem for a while but only recently got the time to take pix and post.
So heres the Skinny....
3 plants of unknown strain all on day 22 of flower.
the tips of one are starting to curl as shown in this pic:


Next problem is focused more so on the remaining two plants. these guys are beginning to curl a bit as well, but more worrysome is the fact that some of the tips are brown and withered...they look completely DEAD, i dont even know if its possible to bring them back, but i would like to prevent the spread. any info would be greatly appreciated.


PS. ive got them on Miracle grow bloombooster and the temps are steady around 75. 80 at tops.

thx for any info

Cinci could be right. It looks a bit like a nutrient imbalance. I would snip off the dead parts of the leaves. No worries, it won't hurt your plant. In fact, it makes it much easier for the plant to cope, as opposed to just leaving dead matter that won't heal on there. Give the leaves a nice daily misting. Maybe even a very light foliar feeding every now and then.

From the pictures, I really can't tell what the problem is. Your plant could be root-bound, and thus wouldn't metabolize the nutrients properly. It may be underfed. I don't know what you're using, or what your feeding schedule is. But from my personal experience, it looks like you might have overdone it with nutes. Are you sure that the leaf tips didn't touch any lights, hot surfaces, or was exposed to excessive heat? Because those will cause damage exactly like what appears here. If not, then just regulate the nutes, transpant if you think the roots are feeling a bit claustorphobic, trim the leaves, and mist daily. Your plants look fine, overall... I'd just give them a little bit of extra attention.

I'm sure Mogie or one of the veterans around here who know what specific nutrient difficiencies or toxicities look like could help you out a bit more.

Skinny is over-fertilised. The next two could be the same or could be nutrient deficient - hard to say without more information.

Soil type? Fertiliser NPK? Feed schedule? Plant pot size and length of time in pots?
