My OG's are starting to yellow much earlier than I am used to. Pictures are taken on day 35 and they're supposed to be around 8 weeks of flower. Could the yellowing be due to high pH in the medium or maybe disease or am I just being paranoid?

Leaves curling on sides
Okay so the leaves are acting weird and kinda curling in on the sides. Like it's heat issue. I think maybe to strong LEDs. Idk. It's only 79°f Light (ESv300) is on lowest setting @32in away. Fed GH flora trio. Only 237ppm. The leaves are also yellowing between veins.

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Mg deficiency?
2/3 of these girls are turning yellow between the veins. I’ve been doing a 1tbsp/gal Epsom sly foliage spray & added same to 1 gal when feeding today. Grown in compost/perlite with some soil mixed in. The Durban looks good but the Ghost and the GSC both seem Mg def right?

Veins turning light green on lower leaves
One of my plants is getting light green veins on the lower leaves. Is this magnesium deficiency? I can't water currently without risking overwatering, can I just foliar spray BioBizz cal mag to temporarily help recovery? Or is this something else entirely?

Interveinal chlorosis on older and new leaves. Magnesium deficiency?
I've been maintaining my nutrient mix pH at 6.2-6.3 as recommended by Biobizz. However Ive been noticing magnesium deficiency like symptoms on the older and newer leaves. Should I increase my pH to 6.5-6.7 or is this something else entirely?

Hello weed doctors, I need help identifying the problem and gathering advice how to enhance my second grow. It's only day 29 and my girls are sick, wh
I'm in biobizz lightmix. Started biogrow on D24, the dose was 50% in 400ml water. Until D24 only rootjuice. Yesterday gave 1400ml each, with 100% biogrow, pH6.4 EC 1.1. My water is hard pH7.7 EC0.8, so I wasn't adding calmag yet. There was 400ml runoff EC 1.9 - why? What do I do?

Yellowing on lower, older leaves. Starts with crispy tip, curling downwards then slowly progress to the whole leaf. The leaves haven't started falling off yet but I feel if it doesn't get resolved soon then this will be the next step. Thanks for the help.

Leaves Showing yellow edges and banding
Is yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise
