Can she be saved?

She will be just fine..............next time, if you need to go away for an extended period, reduce your lighting intensity to 50% if possible and this will limit stresses. "Bottom" watering/ "top" watering will have absolutely no different effects on plant health. I can't see any evidence at all of "re-vegging", you have nothing to worry about.....continue as planned! Addressing pH, while beneficial, it might be too late to have any real impact on this plant, this close to harvest. Don't stress yourself!

Hi thanks for the response, I don't really understand tho what do you mean by she's looking really strange? I agree she's not looking healthy, but what's strange?? She's an purple bud autoflower, I'm no pro but my understanding is that autos can't go back into veg once they flower. I just did a pH lest before I went on my trip and the pH is way high. But I had no time buying pH down untill now. She started having some yellow leaves few weeks ago, I thought it's magnesium deficiency, but now that I did the pH test I guess it's pH issue and maybe also magnesium deficiency... I'm feeding her biobizz bloom, topmax, heaven and tiny amount of calmag. She actually started looking healthier just before I went on my trip, (I thought the calmag was helping) but now I might have managed to kill her 😭 I read somewhere that itight be a good idea to bottom water. Anybody has experience with that??

It's an auto so theres no reveg bro. Looks like I see a few white hairs, not many, and the others are pulling back. When was the last feed? Looks to me like she's either hungry or she's starting her fade. I don't see burnt tips or leaf finger margins so I'd probably go towards the fade. Do you keep track of ph and ppm?

She looks strange, cant make my mind either was reveging in mid flower or is polinated. Bud form strange, from far looks not far from harvest, but close ups very strange ... Some mycorrhizae would help to relief stress.
