My plants do not growing

Imo, extra calcium mainly, some magnesium, perhaps some phosphor, micronutrients. Fishmix stuff is good, but I dunno about typical calmag supplements (imo too heavy on magnesium, when people use like coco, perlite, etc...they OFTEN lack calcium, relatively).

@HighRoller909 Thank you! I will start watering with fertilizer from the next watering. Hope this solves the problem!

Thank you so much! How much do you recommend feeding the plants? Gorilla Cookies Automatic. I have an Atami clamag. And the Biobiz startup package. @HighRoller909

nice triplet. you see those first leaves becoming very pale as well as newer growth,turning pale. coco + perlite is a very aerated medium,coco itself is already well aerated for explosive growth.But, keep in mind, you are growing in an inert medium which means it doesn't contain nutrients,especially it is lacking calcium and magnesium. I'm growing in coco as well.I have to start feeding right away otherwise it'll pull energy from its tiny leaves,result is this.At week 2,you should start feeding asap. Coco looks like soil physically but has totally different needs. Feed every watering unless you have serious nute burn , feed very often because yours have perlite in it which makes it super aerated tends to dry quick.those babies are starving for sure.don't forget to adjust pH when feeding,set it somewhere between 5.8-6.2

They look fine. Look up other diaries of the same strain, may give you some information.

I give them all possible conditions. Full spectrum LED lamp (18/6), closed growing cabinet with ventilation, water with balanced PH, coconut substrate and perlite. All I can give them I give them and something does not go to me. I brought the seeds from FASTBUDS.
