Grow #1: (WhiteGrape X FruitPunch)

Things are not going well. I assume i fucked up the flush. I think my ph surged high again and is slowly being dropped back down. Its 6.5 at the start of the week in the pots and 5.5 in the res. The plants have stopped growing mostly and All are showing yellow leafs at the bottom of the plant. One plant is so puny I don't think it is worth keeping. I hope I am being super critical, but all that yellowing is very worrying. Things are not improving. The res is back to 7+ again 😑 so are the aquapots. I feel like i'm just DUMPING PH down into the res. Gonna try and lower it again tonight. But I think the plants have been locked out for to long. they are eating themselves from the bottom up now. So much yellowing and now browning. I plucked off sever all the worst ones, but its on all the plants with no end in sight. My top right plant is a joke at this point. pretty discouraging, but trying to see it through and learn to get the ph under control before i move on. Well i feel like there has been some movement over the past few days. i did some LST and it made me realize how much! I have the nuets down to acceptable levels, and will change tomorrow. I'm gonna cut the feed in half for a week and heavily monitor PH and see what happens. I think the back right plant is dead though. Ph is 5.8 in res and holding for past few days. pots are 6.4 ish. trying to get lower. plants still got yellow creep, but also showing lots of bud sites
