Indoor Growing Scrog

Grodan rockwool starter blocks, inserted in 4" rock wool cubes, after having been soaked in distilled water with zero EC, pH-downed to 5.5, reads about 550 EC. Hmm. Start nutrient ramp ups from 550 EC?
By Day 11, I try to aim for an EC of 1.1 by Day 22, 1.3 and then keep it at that for the entire cycle. If you think the plants can handle it, up this to 1.6-1.8max for the last three weeks of flower.
 
Day 13 sour diesel auto. Should I wait for day 15-16 to bend the top?

I would try introducing a bend, and see how the plant reacts. It's a little hard to tell from the photos for me, but looks like you're on about 5/6 nodes at the time these were taken. My personal philosophy is to wait until you're around 7/8 node sites to bend unless a plant is taking longer than around days 15-17 to get that far. Those lower laterals will be super thankful for the extra light!

Made the bend this morning.

( If your main stem bends too much near the base, a second wire, straight, inserted near stem base, can be helpful. Use a plant tie to secure the main stem to the straight wire, an inch or two above dirt level. Then you have the curve of the stem where you want/need it. )
 
I went ahead and just stripped and flattened her out today and figured that any additional growth from the tops I can tuck and weave. 😎

22” across the canopy in any given direction and they are looking like over 100 bud sites (but It gets real hard to count 😅)

One week later (after a serious defoliation already)

I think this is basically the same idea. I run a wire from the base of the plant to the pot as an "anchor" taking load off the roots. Then make my bend going the other direction. You can see it at the bottom of this pic of different plant.

Edit. I didn't on the sour because the stem was much bigger than my previous plants.
