Yellowing leaves autoflower

ArizonaJonezzstarted grow question 5y ago

Both plants are 48 days old. Both get the same nutes. Was looking pretty healthy until today. Fed with cal mag, tiger bloom, big bloom, beastie bloomz, recharge and molasses. Ph at 6.3. Noticed the yellowing happening pretty quickly. What could it be?

What affect does a higher PH level have?Somehow I have been reading my ph meter backwards and have ran 2 Blue Dream Fem at a 7.5 ph level the entire grow cycle. The plants are doing well and look great in week 11. How will this higher ph level affect the end product? Will it affect the taste, smell, or potency? Thanks

Bottom fan leaves turning Yellow on week 8... Emergency, or all good ?I know It's a Nitrogen deficiency. No nuts during veg (and fine!), and she's having flowering nuts since 2 days. I know it's normal at the end of the flowering, but i'm wondering if that's too soon !? Not sure how many time left before harvest!? Big problem or not?

Early growth sick plants - photoperiod Purpling stem, yellowing leaves, droopy leaves - I’m thinking nitrogen deficiency, but I’m not sure if I should add more nutrients or not to my current solution or if I should flush completely. PPM is at 850, and the PH is 6.3. What are your thoughts? Any GH nutrient schedules?
