Anyone got any ideas on how to recover this auto flower

[Garrfield]

Hi guys hoping you can help. Week 3 flower and showing signs of calcium deficiency but I’ve tried to up the calmag but for the past week it’s been stalled and just doesn’t look well. I’ve tried to slightly flush too which I’m waiting on results. Thanks

Probably ph

Using biobizz nutrients so apparently don’t need to PH

Are those leaves just fan leaves or on shoots? I'm a noob, but if I see spotting or yellowing only on fan leaves I don't worry too much. I just prune said leaves

Mainly the fans. It looks to be better now. I changed to easy boost feed and the used PH 6.2 and seems to be looking a lot healthier.
