Purple auto DWC

It's fine, some people flip from seedling in sog setups, its your preference. Obviously the more you veg the more branches and budsites you get but either way expect your plant to at least double in size if it has no issues to stunt it.

It will just result in a smaller plant. That being said if your lady hasn't hit maturity yet she will continue to veg under 12/12 till she hits maturity. Your plant is auto? Autoflowers automatically flower once they hit maturity. No need to lower hours of light... and doing so will reduce your yield and quality. Happy growing and stay lit fam.

Strange growth pattern... it could be the strain, I've seen others grow like this too. Perhaps this strain is more affected by the heat? Speaking of heat, make sure you're using hydroguard or something similar or you really risk root problems. Take a peak at them, make sure you don't have any rot starting. I recommend checking out some other journals with that strain and breeder (just go to your diary and click the strain).

Nute lockout from bad pH. Raise your pH to 6.2 or so. Even in hydroponics, the plants prefer a higher pH in flowering.

That's way too hot. You need to bring down the temperature and bring up your pH.

35c .. drop that alot too 26-28 ish. Put a frozen water bottle in the water to keep it cold. Roots don't like warm water. May need to pull off the stone if still getting rot after fix your temp.
