MaxGrow No.1 - Denial and Error

Switched to GH flora 3 part. Playing around with flood times. The are taking up water at an exponential rate. Started with 3, 3 minute floods, up to 6, 4 minute floods and they're still drying up the puddles within an hour. Plant 1 is ahead of plant 2 by a day but it is half the size🤷‍♂️ Topped day 16. Not obvious in the photos as I had hoped but they bounced back within minutes Thank to evryone who gave their input, every little bit helps🙌 After all your suggestions, I've, backed off the light, backed off the flood time and count. We will see if these girls perk up a little more👍 Day 17 I noticed progression of what I believe to be a calcium deficiency? That's on me, forgot the calmag originally🤦‍♂️ another thing I decided to look into was the twisting of the leaves as the plant 1 is also starting to show. Could my ph be alot higher than I think? 4 gal res I added a couple ml of phosphoric acid at the start and about 1ml a day since(I didnt prep my cube as well as I should of) seems like alot to me. The system would rise from 5.3 to 6.3 throughout the day. A flood cycle doesnt seem to affect the ph, more over time. I am constantly stirring the mix and no my meter is not yet calibrated. I have ordered what I need but I'm considering calibrating with the chemicals I have and doing a res change. Good news is, they do seem a little more lifelike after implementing all your suggestions. Okay drained and rinsed my res, ro water into the tank was holding 6.97ph, good enough for the girls I go out with🤷‍♂️ gonna mix up a batch, do a top feed to waste, and see what happens. It has been nearly 24h since my last flood. Also, struggling with lows of 30% humidity sometimes. Dont know if that plays a role here. Okay something was off.. I did a top feed to waste with fresh 5.3 nutes and the runoff came out at 7.5.. so I did it again...and again...maybe a half doesnt times to each block with no change. I started to reuse the runoff as I wrote off the batch at this point. I then switched to a pump and did recirc feed to each block aprox 20 litres at a time, stopping to rebalance. Literally 100s of litres later I am stable at 5.5....going to drain rinse and refill. The interesting part is that what ever was saturated in those blocks is non conductive, the ec didnt change the entire time🤷‍♂️ Spent the next couple days recovering. Looking better now. Sardine catcher installed.
