These are plant #1 from previous post, about 1/2 inch taller(3.5 total). The damage has been done, its new growth and general growth has red around the margins of the blades on each tip. #4 same deal.

These 2 pictures are from plant #4 from previous post. This one bottom leaves are turning light green and this one also has red tips on the margins of the blades. This one grew about an inch since last pictures(5.5 total). It looks real droopy, parts of the tops of the roots are dried where they stick out the rockwool but as they go to the bottom into the rocks they moist and white, this bad?

Moby dick, MK ultra, bag seed and one of those on the tray is another attitude freebie.
Things im doing differently this time:
Letting the water bubble with the lid off for 24hrs. Then PHing of the water, and then putting the rocks in that I buffered and h2o2 sterilized prior, then I ran it with the rocks and then PHed the water after an hour since I notice a huge PH rise when I first put new rocks in and I want to counteract that as best as possible.
Doing swings now, not starting at 5.8 and keeping it there, going from 5.6-5.8, 6.0 the highest. I'm also starting them in the rocks while only one root is sticking out, it's still white, while all the others had been tanish in color(probably the reason #2 and 3 didn't take root in the buckets).
Things I plan on doing differently:
Starting nutes soft at about 50ppm and working up about maybe 10ppm a day to see how it takes it, I think the pictures above show some burn. Running 300ppm of nutes, total ppm is about 380-390. This too much?
I bought rapid rooters and would like some advice on it from people who use it, but then again I kind of wanna just stick with RW because im switching up too many things and I need to get set with one thing. But then people who I consider skilled growers say they have had issues with RW and switched to a similar-to-rapid-rooters product with great success.
Well thanks for reading and hopefully advising. Or let me suffer and figure it out on my own like you may have had to.
