Could be an iron deficiency. Doesn't look like calcium deficiency.

Yellow veins
Hello growers, my girls have these yellow veins on the leaves, could it be a slightly too low pH and the consequent deficiency of magnesium? How can I act? Can some Epsom salt help? Thanks

Baking Soda for Acidic Soil
How much baking soda should I add to my water to correct acidic soil? Ph meter reads between 5 and 6. I cant afford prepared solutions (but am not opposed to chemicals) so any other DIY remedies would be welcome too

Yellow centre veins fan leaves
Yellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?

Is this nute burn / deficiency? Or light burn? Or both?
What's going on with the intervenial chlorosis? Is it nute burn (zinc + manganese + iron potentially)? Is my proposed solution of only going with pH-balanced water a good mitigation strategy? Should I just not add super soil out of the gate?

Interveinal chlorosis and dead spots on leaves, deficiency?
This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Blue Dream Autos with Downturned Leaf Tips
23 days old. One started showing downturned leaf tips on new growth; others followed. Looks off-color, at least one is in early bloom. They’re in coco, 3-gal pots, 480W QB at 50cm, 2.2 EC daily, no pH check. Problems started after adjusting watering for larger plants. Any tips?

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
