Need help with first hydro grow.

Don't give up man.. I ran DWC outta totes my first run or two and it was a piece of cake. Thought I had it down, and everytime since I have run into issues.. Its a tough medium sometimes. I mainly do coco now and soilless mediums, but theres nothing like that water culture growth when you dial everything in. So first off, I would tone down the nutes. I also run GH flora trio. I would bring those main three down to like 2.5-3 ML each and see how that does. If I was in your shoes now I'd probably do something like 3mL micro, 3 mL grow, 2 mL bloom. I'll add a link for their feed charts to give you an idea of ratios you want to run but the whole chart is made for photoperiods and youre running autos so you will want to reduce feed to account for that. I would remove the Recharge product from your regimen, theres good similar products you can find that are more suitable for hydroponics - "photosynthesis plus" comes to mind. check them out. If you wanna just test things without a whole res change, just empty some out and fill back with water and pH back to where you want it. On the subject of pH - try to be right at 5.8 , it can dip as low as 5.5 or 5.6 , but you dont wanna be above 6 ideally. hope this helps man, heres GH feed chart.. again, its for photos, not autos so you have to keep that in mind. https://edge.generalhydroponics.com/www/uploads/20210121184300/FloraSeries-Basic-Feed-Charts.pdf
