Inter vein yellowing makes me think magnesium. Your supplementing cal mag tho. It’s in coco so are you getting decent runoff with every watering? And have you flushed at all?

This is definitely a molybdenum deficiency. Double check ph.. most of the time that’s the issue. But that’s definitely showing on new growth first from your pics. I also feel your heat is high.. anyway to drop it down?

Looks like the start of a PH issue. Maybe pen is out of calibration? It happened to me.

"It’s in coco so are you getting decent runoff with every watering?" Yes, mostly everytime i have a runoff when i water. I give Cal-Mag 2,5ml for 5 liter water. And i guess the Micro has some Mag inside also? (botanicare: Add 1 tsp (5ml) per gallon of water) "And have you flushed at all? " yes, and buffered the coco coir at begin

Mites, root rot, or light intensity Does anyone know about tiny yellow dots on new developing leaves are a sign of in early veg? Im growing in RDWC so I didn’t think mites would be an issue. I did notice one relatively brownish root as well, but the rest were all white and healthy. what should I do?

You are a SATIVA North Shore Maui! You grow tall like the sky! Strong like mountain! You are not descended from short plant!Currently overthinking this plant's development. Pep talk not working. It is a sativa but the shortest plant in my garden. Maybe just needs a trim? The yellow is a concern too. I haven't dealt with a plant this bushy before so not sure if it needs help or not.

Yellowing leaves Hi Growmies, im in week 7 of my flowering cycle, my leaves have started yellowing between the veins before turning brown and dying from the tip inwards. Is this a calcium deficiency? Or is it natural dying from the end of flowering cycle or something else? Please advise thanks ✌️
