Charbud Reviewed by Charbud on . leaf issues 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. Rating: 5
