HELP! Plant leaves going yellow stopped growing????

soil too hot or/and root rot

can't imagine that soil of yours draining....add some perlite (I use 1/3 perlite makes for good root growth)

edit: never owned or checked ph on any soil grow in last 30 years. But can't use local water (too hard....high alkaline) so I buy Walmart spring water and use collected rainwater when possible.

Okay great, thanks, yeah i'm getting it from my taps and standing it for a while before watering, i'll grab some of that thats what i suspected, though 1 of my plants are sky rocketing and the rest seem a bit stressed i guess.

Have a look...
