leaf issues

[highroller99]

I am having a couple of leaf issues with a plant. The leag fringes seem to be browning and bending upwards on this plant. This is happening on leaves about mid way up the plant I have included pics. I am growing under 400w hps in a soil mix of 5 parts potting soil, 5 parts vermiculite, and 2 parts composted chicken manure. These clones are of Querkle indica strain vegging for 15 days.

Looks like heat stress as the leaves look dry and curling.

Yes it does look like heat stress, however this will only make the leaves closest to the lamp have the problem. If the lower leaves are still healthy looking (hard to tell for sure from your pic), then the next thing I would is make sure your ph is 6.3-6.8
