1st day into flower, Please let me know whats this DEF, HD pic attached

Details:
CFL Lights 60 watts per plant,
Growing with soil Mix 30% perlite,
feeding at every watering with 1/4 strength 20:20:20 + TE and 1/2 spoon Epsom salt.
I just flipped the lights yesterday, woke up to see this yellow new grow !!!!!! is this bcz they where used to 20 hours of light ? and they need time to get used to the 12/12 cycle ?

Plant 1:




Plant 2:

It doesn't look like any sort of def. to me. It looks relatively healthy to me.

Good Luck!

i wouldn't feed them so much yet.

i started to feed 2 weeks ago, they where dying before i started to feed
Before feed :

Are you watering with pH'd water ?
Are your lights still 60 watts / plant ? there're much bigger now, switch light to stronger ones and check out this pic :View attachment 2999379

thank you for your replies guys, i think that happened cz the plant had no light all over the night and it might turn back green if the lights stay on for the next 12 hours i will leave it for couple of days and then i will update you guys on this situation.

Chlorophyll is manufactured from light, low light= minimal photosynthesis and minimal metabolic rates, leaves a lack of pigment (green color). Increase light and also fertilizer appropriately. Also most likely a lack of iron
and/or sulfur. Ca,Mg,Su are your secondary nutrients and they are needed slightly less than your primary (N-P-K).

Whats the soil mix? Im questioning the soils CEC ratio, and also in relation to the rate of drainage.

Keeping lights is not the solution ! I find 60 watts very low for such plants !!

I will keep the lights on 12/12, my grow area is 3' Square foot and i will add more lights to have:

4X36 watts tubes 6500
7X36 watts CFL 2700

so total of 400 watts, is that fine ?
