The color of the leaves is yellow and wilting

Hello
I'm having some problems
I have 2 plants with problems
The first one suffers from yellowing of the lower leaves. I don’t know whether it is nitrogen deficiency or what
The second suffers from wilt or prolapse
Illumination: led king plus 1200w
The height of the light above the plant : 40cm
the soil : bitmos + perlite 35%
Water pH: 6.5
Compost: I have not used fertilizer yet

Is the soil dry or too wet? How is the humidity?

pH is good so that's not the problem.

Do a run off/out test and see what PPM water comes out.
Pay attention to what PH goes in and what the PH it comes out as.

Maybe a pic under a white light.
Some plants just go crazy for whatever reason under those colored LED's.
I could be that......

40 cm seems close for a 1200w led
What’s that like 20”
LED is not my forte really but I’d suggest raising the light another 20 cm or so see if that helps at all.

40cm is closer to 16 inches.

Remember the lower leaves are the oldest, and if one gets funky its ok.
The lower leaves easily get starved for light, touch the media, rub on a support object etc. All of which can make a leaf look funky.

How is the top 2 set of leaves doing? They would be a better indicator of health.
If the plants are not thirsty, then how hot is it at the top leaves? If its too hot for your hand it too hot for the girls.
