At a glance, it looks like thrips damage. Go get Captain Jack's Deadbug Brew. Should be available in Home Depot, Lowes, Walmart, some local hardware stores... It's a safe foliar spray. 3 applications 3-4 days apart, and problem solved.
Oooh, didn't know Captain's was so good that aphids died too. I knew I loved the stuff. It just went even higher in my regard, though.
Doesn't say aphids on the label, but I have used it outdoors on veggies and it works on them!! Contains Neem oil too
Well first hit them with something that will kill them on contact , than spray with a mix of neem oil and all natural soap ( not detergent ) for two weeks to cut the lifecycle .
You mean like spraying with the Captain Jack's that we've recommended? Since it's an all-in-one solution without scary chemicals? And 3 applications kills the lifecycle, so no need for neem and soap. Just the one thing.
I don't have Captain Jack's at my country, but maybe you know something else that could kill them? Soap water foliar spray?
Scary chemicals I never suggested any chemicals??? Wtf lol I said neem and soap and something to kill on contact . Like insecticidal soap .
In many, many years of experience in a retail greenhouse (just houseplants, annuals, perennials, boring stuff), neem and soap have never once worked on thrips OR aphids. Neither does insecticidal soap. The Captain Jack *DOES* work. Without knowing what country OP is in, I can't recommend an alternative, but there may be an alternative brand. You're looking for any brand of spinosad.
Actually you are right , thrips are a bitch when it comes to neem . But soaps will kill them , but spinosad is a great product for thrips .
id throw some sticky traps in there. like fly paper... and mix a strong soapy water solution,,, use DAWN dishsoap...for killing bugs dawn is the best. and on your next grow. since you now know you could have a future bug problem.. use a SYSTEMIC poision.. at about the first 4 true leaves. and you'll never have to spray for the rest of the grow, a systemic poision stays in the plant thru it's whole life.
