I messed up please help!

This is my first grow ever and im really bad at it. I have 4 plants under 4 23 w clf. The problems originated from the start with using the wrong soil. I am used the MG Potting mix that feed plants for 3 months. Ive been having problems with browning leaves for a wile now. I messed up a few days ago and forgot to water the plants they looked so horable after that. they did revive once i watered them though just with the leaves looking bad but they have grown alot. I just want any advice you can give me.

Do you think i should change and transport to a different soil mix? What about the lights should i add more or wait? I think im around 20 days into the grow.

Im no pro but i think u should transplant them into a bigger pot , flush them then give them 1/4 nutes and see how they respond. I hear the more light the better but its up to you they look fine beside the minor issuses.. Good luck and Happy growing!

doesn't look like you're doing too badly. I would def flush and depending on your root growth, transplant into what you want to stick with. How long have they been in that soil?

I c some nut burn....Use flush with fresh water no nuts add.....3 times
