What is wrong?

About 2 months old. Transplanted late. Super cropped, topped & LST. Help explain deficiencies also ?

Its a bad idea to plant multiple girls in one pot. Did you mix your soil or buy it? Do you pH it looks a bit like ph outta whack...slight N deficiency..

One looks burnt

Looks like heat stress, are they outside?

Yes there outside . I only put them together because I didn't have no more soil or buckets and my budget is low right now until I crop out . Yes I've had a heat wave for a week and kno ph meter I got a cheap one today I'm going to water proof it. there all bag seeds I'm going to get some auto flowers hopefully I can finish up outside it's my first time but I've be reading about this for years but I need some advice also I'm using a cheap fert ozmokote or some shit like that but two of them showing sex already one has white hairs other is swollen below the nodes so I think it's male shud I rip it out ? Thanks guys

O my soil mixture is miracle grow moisture control mixed with sand clay and rocks I don't know if this was a bad idea but you live and you learn

I just don't know how it could be heat when none of the other plants showed signs of being burnt
