UNKNOWN STRAIN DID I FIND GOOD SEEDS?

Hey guys this is my first coco grow.
Found 6 seeds from what me and my gf believe 3 diff type of oz bags. 3 germ 3 died. Turn s out got 3 females from them.

14th March from seed. Here they are. 7th week from 12/12 say about 5th week into flowering. I didn't have Ph or ec tds meters so I was in dark with what was going in. Just got meters last week.
So now I can Ph and ppm them.
Plants are 40inchs tall.

Made one into a mother and clones.... rooted in 10 days.
150w cfl.
600hps.
Canna A+B and just brought pk 13/14.

Buds look kind of small for 6+ weeks of 12/12, I'm guessing you have a light leak.

and or root bound

I have light leak from other room do U think it is the problem.? The one with heaps of heads popping out is 2 weeks younger then the stockier one. Its suffered toxicity coz I didn't have ec ppm or Ph meter.
But have worried about this light leak shit.... hmmmmm

Should I remove mother clone room light completely out of flower room? The buds haven't grown on that one plant been same 2 weeks now but the other one has grown.... wtf....... pots are 8 litres or 2gallon.... in ur country.

What should I do prepare for new lot of babies coming in after this.I might upgrade to 3gallon.pots. and complete relocate my mother n clones any tips?

A cannabis plant can handle light slightly brighter than the full moon without revegging, it will slowdown growth though. Just get it as best you can.

I'm kind of a newb but I was just researching pot sizes for myself and I would say they are too small. One basic way to tell is 1 gallon per month. So your at 3 months now I would go at least 3 gallon, but personally I would use 5 gallon pails.

you need to transplant those to a 5 gal pot atleast. Coco can be done in 2 gallon fabric containers but they will quickly become rootbound in a plastic pot that small after 2 months. Rootbound plants bud production is stunted.
