It's day 17(Dec9) and my leaves have a strange discoloration. I can't seem to find out the problem. I have uploaded a picture of how it looks in detail Under week3. Only the older leaves have it with the oldest having the most discoloration.

Too much light or other deficiency
Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

Eagers
Twisted/mottled growth
Not a happy plant, was on a windowsill in 30c back 6 days ago and think the roots were overheated? Transplanted to final pot and have been foliar feeding since but no improvements (gained about 3cm in height!) Found caterpillars yesterday so removed leaves. Will she bounce back?
