Any ideas ?

Morning all. I have 24 strawberry fire alien Mac and 24 peanut butter breathe in the same ebb and grow sharing a res. I noticed a few leaves on the sfam with this but none on pbb. 6.0 ph , 1000 ppm, 1500ppm co2, end of wk1 flower. Advanced nutes , enzymes komplete. I don’t think it’s light related as a few leaves are down low . I looked through scope and can’t see anything moving on the surface . Thanks in advance!

I'm thinking it's got to be pest related.

Looks like russet or broad mite damage better get a better scope at least a 60X. Were these clones that were brought in?

No I started these from seed . I do keep a couple thousand lady bugs in there most of the time as well

Looks like caterpillar damage.

You need to look again.. That's pest damage..

Thanks for your input y’all. I’ll check when I get over to the shop in the morning . I did do some reading and saw lady’s won’t work on them being they are too small. I do have some nematode beads from arbico so I’ll water those in regardless. I read topical sulfur is a good treatment too . Just a little concerned being that I’m in flower. I feel like week 1 is safe to apply it but not sure about that. I try to use natural products and not go nuclear . Anyone have any products that you had good success with? I have some pure crop 1 which is great but not crazy strong . Also have some suffoil x which I have not opened yet or tried . Anyone ever try it ? Both are from arbico
