Is it too late for LST or topping? | Also, wilting concerns

[Bukk]

Hello all!
I am 4 weeks into veg and am just wondering if there’s still time for LST, topping, lollipopping, etc. I’m doing RDWC- 2 plants in a 4x4 and 2 plants in a 3x3. Did I wait too long to start to Scrog? Doing a scrog along with other training methods is my ultimate goal, but I’m not sure if it’s too late. Also I’m not sure why my one plant is like half the size of the other one and wilting. I’m a noob at all this (first grow), but I’m eager to learn more! Any advice is always appreciated!

It's not too late for LST or topping, but you are right to be concerned about the plant health, something looks off. What is the pH and EC in the reservoir?

 

[Bukk]

pH is 5.8 in 4x4 and 5.9 in 3x3. Both EC is ~1.75. Both ppm ~800

That might be too high on the EC, but I don't know that alone would cause what you are seeing. How do the roots look and smell; are you using beneficial bacteria like hydroguard? Is the pH stable or do you have to keep adjusting it?

Edit - just saw your other post about root-rot, it looks like you are on the right track, I wish you luck! :)

I changed the reservoir water out 3 days ago. I started using Orca for a bb. I ordered Hydroguard because my hydroponic store didn’t have any. The roots are slightly brown but don’t have any odor. I had a post about that yesterday but I think the roots are already responding positively to the bb.
