First Grow - Purple leaves issues

Hey guys, almost two months in and 3 weeks into flower.

One of my Mimosa Evo's has gone very purple, the edges of the leaves and stalks. The others just have purplish stalks but I think that's genetics when flowering. The problem plant is very droopy as well as purple leaves. There is nothing different about that plant other than its positioned next to the intake where the heat comes in. Any thoughts?

The other pics are 1x Northern Lights Auto (1 week younger than the rest) and the rest Mimosa Evo photo period. The auto has been on a 12/12 for 3 weeks and looks and smells great

Last pic is a caterpillar I found outside the tent which is odd as the tent is indoors

I made a tea using boiled banana skins, sugar and honey and fed it to the front row and not the back row to see if I can notice and difference

Any idea why it would affect 1 out of 4 plants under the same conditions?

Possibly root issues. Not there to see.

Thanks for the reply, boring question for you;

I potted these in 5gal pots but didn't put enough soul in. Come week 4 I realised this and rather than repot I slit the pots sides and folded them down to allow the lower leaves to get light. That particular plant has the lowest soul, I'd say 2.5gal, possible too much nutes given the low soil content?

Bananas and sugar tea is completely unnecessary and is more likely to cause issues rather than fix anything

Very possible. Rootbound is a possibility in a container with that small amount of medium.

Is it too late to repot?

Just cut the bottom of the bag out and set it on a container with your medium.

Plants will not reach full potential on just calmag, bat turds, and boiled banana peels. What type of medium are you growing in?

A simple well-balanced feed with all required nutrients would be a better option

I prefer Maxi Gro/Bloom but there are many viable options

BTW - that O2 bag adds nothing in a tent setting. Also, that light mix will tap out sooner than later ( think of it more like a starter mix ).
You need a complete feed vs. banana water. Look to simple to part nute lines like GH MAXIGROW / MAXIBLOOM powder .

Simple to mix and use .
