First of all, congrats on the grow, it looks nice and the BP RF3 Auto can definitely do a lot!
I would say you're on track for a successful harvest and you can mostly make things worse rather than better at this point. I would just give her water and ride out any potential deficiencies. Of course, it's important to take the right precautions for the next grow to avoid repeating the mistake. At the beginning, I often tried to correct every deficiency or environmental influence right away, and usually ended up overcompensating or putting the plant under new stress. Now I force myself to make more long-term changes and the grows are looking better and better.
In that sense, enjoy it for now and put your energy into fine-tuning for the next round!
