Help to identify please

Hello everyone,

I'm back up and rolling after the move ,!

Super excited, I used sen extra cash to get a few LED lightsnn gna document that soon enough (3 solar system type or sme like that)

Anyway I want run them with nice healthy plants and that is where my problem is at the moment ...

I'll attach a photo but basically idk if it's the clones I got from store or if it's the dirt but I ended up with little flying bugs that I think are aphids so I used some stuff called promis and didn't effect any of the Harlox strain buyout the death star looks like it got some bad nute burn or salt build-up or smp.

It's been about two weeks feeding nothing but straight water and the new growth still looks gnarly and so I wanted to see if anyone had any ideas on this .. maybe it is sme sort of nute deficiency

Never grown death star so it may be a sensitive strain cuz the Harlox is looks great .. newly me help or ideas ?

Solar system 550s

Knocked the aphids back too, there isn't much of nothing on the sticky traps and I wana do a root dunk to keep it that way but worried about these guys so I've been holding off ...

If you're watering too often you can attract gnats. Let your soil dry up a good 3-4 cm from the surface before giving another drink. Also. Keep your water/feed pH to 6.5 if doing soil.

You can add in predators of aphids if you wish. Lady bugs will do it.

You could also sprinkle your medium with food grade Diatomaceous earth. That stuff is like broken glass to most insect larvae.

Your other option is to place yellow sticky traps around the area. This will notify you of an outbreak of any flying critters in your op.
