That first pic looks like mine when my PH is locked up. I notice it takes a few waterings to get it back on track (you didn't say if you flushed, or just watered). If it were me, which it has been twice in my first grow, I would continue to water with R/O water until you get that PH tester. I got mine in the pool/hot tub chemical section for 10.00. Good Luck, :jointsmile: Bree.
