Welcome to RIU bucketgirl.......
"the claw" its an over nute.
your ph is a bit high as well, i'd drop it down to around 6 so it has room to drift on you. 6.5 is the high mark for hydro, you dont want to be any higher than that to be safe.
ive heard hydro between 5.5 & 6.5, im around 6 in coco, i adjust when it hits 6.5, and all is well. i like to sit right at 6 for my ph, im passive hydro as well - 1 gal pots, hand watering.
5.5 to 5.8 doesnt give you mush leeway for drift and might be difficult to keep it there as your nutes are being eaten up, and the salts are building up.
soil 5.8 to 6.8...ive run up to 7 for soil with only light nitrate lockouts fixed with a flush.
i would flush real good, then start my nutes up at 1/4 strength.....monitor, then up your nutes gradually. you are going to want to flush once a week to remove the salt buildup from the nutes before they become toxic to your babies.
disclaimer: i use coco, this is my first run with coco. it is a bit different from perlite and vermiculite so use my post as reference....its all trial and error, whatever works for you and your system. but there are a few general rules to follow overall, just keep your ph under control, watch your plants and see what they are saying to you. going to take some close calls until you learn all the ins and outs of what issues look like. any sign of issues get back here and do your research, and ask many people. you will find contradicting info, but with some conversations you can generally get to the bottom of whats going on. RIU rocks, the people here are freaking awsome!
again welcome and good luck, hope this helps you out a bit.
