Hmm it doesn’t look that big but I’m sure you know
No clue on your soil mix
I’ll still say that thing looks to big for its pot
What are you doing for lights and how long has she been vegging ?

honestly i do everything the same all the time, except for some training i experiment sometimes, and it's all gone well with pretty good yields but this time it all seems to be going wrong and i don't know why .. it's been in vegetative state for 50 days and i usually first 2 months with pre-fertilized soil and from the first day of flowering I start with the advanced nutrient fertilizers .. I wanted to send them to bloom tomorrow but I'm afraid that if I leave now that they have problems I will have a bad yield. Mars Hydro Tsw2000 18/6 38cm above the tips

That’s a good root trimming pot
Are the others the same type?
Blackketch

yes the same but the latter has only 2/3 liters more capacity .. however you think it is normal that the tops are so light / yellow? I have always noticed that the new buds have this color but this time they are worrying me .. and I don't understand a thing, if it were a deficiency it shouldn't start from the lowest leaves? here it seems that the others are dark green and those at the top light green

This is just a guess but
My experience with those pots is they are hard to water thoroughly as the roots buildup
Mine won’t even fit in a five gallon bucket , so water keeps coming out the sides rather than soaking all medium
That is my only thought that you may not be soaking the pot thoroughly

oh yes, unfortunately these pots have this problem but I can still solve it by watering very slowly! however I assure you that the plants receive water homogeneously throughout the soil

This is a pretty good site.
If it's new growth its possible zinc or iron according to what is posted.
The one I started 2 months ago had lighter colored leaves starting with the second set of new growth. I noticed they were not as green.
