What do do you see here ?

Looks like some standard leaf mutations in the first one. not all leaves are perfect. The 2nd one looks like it has dirt on the leaves and they both spear to be frosty. Looks nice, plants do this in times of stress if its not really their normal go to. My outdoors plants always get extra frosty from the bugs attacking them. They almost always get a bit of aphids and it makes em bulk up in trichomes. avoid neem on things you want to consume. its not great. and most neem have the active ingredient removed as its hazardous. Use BTi for contoral of gnats and thrips. can also spray it on the leaves if you want. but don't spray when lights are on or if you do. difuse the light and dim it till its dry.

Just had a quick look and yeah uv been spraying with neemoil, probably while the lights are on aswell.. that's your problem

What I see is your plants under serious stress. I’d just observe and let them grow out a bit. Water correctly and do a light feeding until some leaves have developed and it starts growing again. These stress related problems will slowly work themself out.

I would say you have a very dry and or hot grow area and I would say you have sprayed spilt or watered over foliage, it's damaged anyway. Human error I think.

k-def, p-tox? too early to tell from leaf symptoms. You aren't spraying your plantn with some bro-science nonsense, eh? Is the first leaf pictured one of the first few sets? might explain the blemishes. those don't seem to be occurring on new growth of 2nd picture provided. I'd wager something is too high or being inhibited (mulder's chart can help). May need to let this prgress a bit further to avoid compounding the problem with a bad guess and wrong reaction. yeah, that first picture looks to have trichomes. trichomes on fan leavs may correlate to something good but in and of itseld doesn't really mean much.
