the problem i see is that hose bottom leaves are touching the soil top, and the sides of the pot, i would suggest taking off those lower leaves and
make sure none touch the top of the soil.
so if you cut them off you will prob. start seeing improvements with in the week.
when the leaves touch the top of the grow medium all kinds of funky stuff happens to the plant, it is no good.
so cut them of and keep an eye on things, but your grow will improve. hopew this helps. happy growing
