One of my plants is sick anyone got any suggestions

They started showing me theses spots this morning... :/

Hopefully just a minor deficiency/toxicity but unfortunately it could also be spider mites(which is less likely due to you being in hydro, but still good possibility). Do you also have any soil grows nearby? I just had plants this summer that had very similar looking spotted leaves and I thought it was a deficiency but then ended up finding out it was spider mites when they webbed over a cola. Check underneath your leaves and look for spider mites. Do some research on em to know what to look for

If its not spider mites, then prolly nute problem. Whats ur PH and PPM/EC readings?

Best of luck man, hope its not spider mites, fuck those little fuckers!!!!

I found out it was a nute problem... I'm a noob to dwc and hydro in general I was way under feeding them on nutes. and yeah I was afraid of mites as well but new leaves are looking good and I checked under leaves very closely no sign of mites

How they are doing at the moment. This is at 1.5 weeks in

They should turn out nice for you. Good luck man!
