leaf tips curling down?

These plants are mostly healthy (I am in the middle of treating for Thrips). They are just finishing up week one of flower and i notice the tips of some of the leaves are drooping and curling under. My soil is moist (but i let it dry between waterings)
humidity 20-30 heat anywhere from 25c-30c in light and down to 20c during dark periods.
any ideas?

Hi there i seem to have a similar problem, is there some kind of natural way of killing root bugs? I don't know what I have but when i watered last night hundreds were flushed out, only some of the leaves are curling down, sounds similar to the problem you're having. You haven't overfed, you haven't over watered but the leaves still curl. I look forward to finding a solution to this problem as well.

I found this sticky very helpful for dealing with bugs (along with help from other forum users), hope it helps out your problem! hope mine isn't too serious!

I've had thrips, so I feel your pain. I found HotShots Pest strips to work great. Just thought I'd share. Your plants look just fine to me btw.

Thanks for the input! I've got some pest strips in there and am also spraying once a week so I'm hoping to be rid of the thrips soon! Not to worry about the leaf curl then?

Its not so much a pest strip. It emits a vapor that kills insects. I've found no ill effects from them on my plants either. A little leaf curl is nothing to worry about. Your garden looks great.

oh ok! thanks again

Here's an interesting little link i found whilst searching for pests, maybe you could use some of these tips as well as the strips?
