Drooping leaves
The water pH wasn't right before but it's been at 6 for the past 5 days and the leaves are still drooping and seemingly yellowing albeit at a snail's pace. Water her every 2-3 days + 0.5 ml of feed once a week so not sure what the problem is currently? It's an organic grow.

Yellowing… why, N, maybe Mag….😭
1/4 plants yellowing it’s the biggest and is the only one that fell victim to a topping in veg, N def? The interveinal stuff is making me think magnesium too? What y’all think…

Help calcium deficiency
I think I have a bad case of calcium deficiency? This started shortly after switched to 12/12. I added 1/4 tsp to a liter of water 2 days ago. I’m not seeing improvement. Am I right ? Will the leaves turn back green (how long)? Is it something else? Will it die?

Beginning of Budrot
Is this the beginning of budrot or just the plant using the leafs (sugarleaf actually) as nutrients? I'm in the final week and in 2 days this leaf starts turning yellow on the bud. Bit worried. I cant pull the leaf out and bud looks fine but still worried

Do I have an Iron Deficiency, if so How do I increase Iron levels (Already using Calmag)
I think I have an iron deficiency. New Growth is appearing yellow. HYDRO Rain water - (20ppm) PPM 750-900 (just upped) Canna Aqua A+B Calmag (0.35ml/L) PH was 6.2 (as there was a calcium deficiency so I raised it slightly) PH is now 5.8 (I read lower PH is better for Iron Intake

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

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.

Organic grow, yellow leaves, autoflower
First ever grow. I'm in my 5th week of autoflower, organic grow. Using the bomb paonia soil, raging kush light and boogie brew tea and filter to water. Temps are steady around 86. Started noticing yellowing on bottom leaves. I'm pretty sure it's from under watering? any feedback?
