Hi, my plant started turning yellow a few weeks ago when i changed from cfl (285w) to hid (600w) and i thought i had scorched it at first like the other one which has burns on it. Changed back to cfl, no change. Leaves turned as yellow at the bottom as at the top.

She turned totally yellow very quickly.

This is a pic of the burnt one (brown nobbles on upper leaves) with the lower leaves turning brown since changed back to cfl, so not heat.
