Make sure your water temp is lower like add ice to it to cool it down as if it’s to hot you will start to get root rot causing loss of growth leafs turning brown and falling off = dead plant

@DrDime Hi mate looks like ph fluctuations to me Ideally in hydro you want that ph below 6 preferably 5.5-5.9 Hope this helps

Hey there, those spots could be one of two things. Either pests, and just to make sure , check underneath the leafs : if you see microscopic black spots under the leafs, i'm sorry to say you might have spidermites . If that's the case try BT, that's what works for me, and it's bio. What i think is more likely is that you're seeing the first signs of calcium deficiency : you can tell by the scaterred rust spots on the leafs. Try adding more calmag to your feed or making a foliar spray with 3ml/L twice to three times a week just before lights on. The problem should stop spreading and the plant should recover in 7 to ten days. Hope this helps ! 🚀

I would suspect a pH issue from the look of it. If you have had any fluctuations far out of range it could be the cause.
