Purple punch auto

Started to show signs of cal mag deficiency for the past week or 2. It was because the ph at the roots was 5.7 so i flushed it this week with higher ph and it seems to be doing better now that the ph at the roots is at 6.2. First autoflower indoors for me so its a learning experience, my outdoor purple punches turned out like crap on my balcony this year so im curious to see what this one will turn out like in the tent.
