Looking sad after re-potting

Typically you shouldn't uppot autos at all pal. You can be it needs to be done with lil stress and needs to be done within the 1st 7-10days and even then it's not recommended. You don't uppot an auto as the stress triggers it to flip. As with photos any stress you just push through and control the flip with changing the hrs. Autos can be triggered by stress or IR730nm

When you transplant you need to water it in thoroughly. Even then it sometimes takes a day or two for it to acclimate and perk back up.

Give time. Never feed during heavy training sessions, better plain phed water. Have you watered enough ? Roots need to run and search for it, they dont run in dry medium. Lift leaves for them not to touch soil/medium. Either garden wirws or just training should help.

150ml of water seems to be too little for that pot size, make sure to always irrigate fully after a transplant with at least 10% of the soil volume
