dont take as offence, but i see lots off mistakes ;)
keep room as tidy and as empty as you can, better and more air and circulation
never plant two plants in one pot. solution - transplant while its not too late.
never use light transparent ( in your case white ) pots, roots dont see light, you will stress plant. cover with black duck tape, use dark paint or something.
more holes in plastic buckets, better drainage. drill way more on bottom sides and bottom.
pots should always be filled till verge, better air, no stagnant or mouldy air pocket . i would take all out, add on bottom, that way height would even up. with fabric pots ( which are cheap and works amazing ) you would just roll down as sock...
by colour they look heavily fed, pro mix is very potent, plus you boosted it with worm castings, pure phed water diet for 2-3 weeks, aka no feeding ;)
2.5 g from 1W is Gods mode btw, so thats your max posible, wish you to be very close !
