I have 8 plants. All autoflowers in DWC. 6X4 grow box. 2/1000w leds. Flora gro series. All on week 5 of veg.

I was trimming the lower canopy and found 3 leaves that concern me. All from different plants. Can anyone tell me what might cause these issues.

First pic has dark discolouration on tip of leaf and it is curling


Second picture the stem has split vertically


Third pic looks like something has been eating the leaf. But I am using DWC and I thought bugs and such were much less of a worry without soil. Is there a bug I need to be looking for?

Any help is greatly appreciated.

Bugs like plants period they don't care what they're grown in.

Next time scrog or at least LST that strain - lowers would have been able to get better light.

I wouldn’t hyper focus on three leaves … as long as it is not a systemic plant wide issue . Twisted / torn / partial repair to itself / etc. happens to leaf especially in the bottom shadowy areas .

I would try to “ supplement “ some lower lighting and give those lowers a chance - say NO TO LARF

Right on. Trust me I never intended to grow too many plants for my box, but that's what's going on right now. I have the one in bloom that has about 4 weeks left. The other 8 are in mid-late veg. This is a 6 plant box going forward, but there's 9 now and so I have to deal with it. I barely stressed trained that forst plant because it was my first grow ever and I still don't know what I'm doing to be honest. But with the 8 new ones I attempted to lst better (with little luck) and I'm trimming the lower canopies because it's basically a sog in there and there's just no way they are getting light and they're about to bush up anyway. I don't want another monster plant with 50 little colas again. I'd like the new plants to focus more on fewer colas.

Also those leaves are from 3 of the smaller plants. I have.other issues with the big one I'm trying to remedy, but that's in a different thread.
