I this is big is it gets in this pot?

My plants are about 14-16 inches tall after 2 months they are in 8" pots did they stop because they are out of root space?

Those pots are more than enough...Looks like you've used too much nutes or something...somethings not right. Flush 'em and leave 'em be for awhile, they'll bounce back.

They should be a lot healthier, they should be dark green. What soil, nutes, pH of the water, how often do you water?

i think we need all the information you can give. strain, what feed and how often, what growing medium, what lights. tell us more and did you cut the fans off.?

They look over fertilized and over watered. The pots can certainly support larger plants than that.

def bad soil IMO look at the seedlings even. nut burn IMO. switchem to diffrent soil or hope a good flush will work

hmm wouldnt have used nute's at all atleast until putting them into 12/12...just seems to make peoples plats go yellow and look shit also with stunted growth just seems a waste of time .. the most healthy plant ive seen was @ 3weeks old and was watered with tap water.was very very bushy and like 12inch's tall

im guessing he used a MG or other nut rich soil which is burning the seedlings.
