Nutrient burn, Ove-watering, or both?

I have 6 plants... transferred them all to large pots with pretty much the same soil mix.... 2 are going great, 2 not so great, and 2 are shit house.. this is my best and worst... any help on how to get them all pumping?

Dat first one looks like nute burn and over water, second one looks pretty good, the soil should have enough nutes in it already providing it's good soil( not that miracle grow crap.) I'd say let the soil dry out and only water wit just water, also patience is key, try to keep ur mind off of em and don't smother ur babies

I'd say both over watering and nute burn, leave it to dry out properly, give it ph'd water for few weeks, your soil should have enough nutes in to last u about a month

What is your soil mix?
