yellow/copper appearance in some leaves after first run off watering

enthusiast_growerstarted grow question 4y ago

hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?

Looks like calcium deficiency. If there is coco in your soil mix cal mag is always required.

Copper Bronze look can be related to excess chlorine or iron. Tap water usually has chlorine in it and its recommended to let it sit for 24h-48h to gas off before using.

First signs of burning from too much/too strong nutrients, as evidenced by the super green leaves. Is there a product you are not feeding them with??? Wow!

Hi! im experiencing yellowing and falling leaves in all the strains i planted 5 weeks ago. Only lower leaves. Thought it could be nitrogen deficency but already fed them with N nutrient and still slowly yellowing from bottom to top. All plants are in early flowering stage.

Leaves down Hello,fellow growers. My Royal cheese 🧀 seems to be doing not so well in her second week. Leaves are turning yellow and down. Can this be because of overwatering ? I gave her two litters of water two days earlier and now it's all sad. Please help me out.

What is this rust discoloration on leaves, and how can I stop it?Does anyone happen to know what is causing this rust colored discoloration on fan leaves? It starts on bottom leaves, and moves up. Also seeing yellowing on leaves, and not sure if its pest issue, light issue, deficiency, or watering concern. Super nervous plants are dying🙁

Small yellow/brown spots. Rest of plant looks fine. 5 days into Veg About 5 days into veg. 7 gal smart pots. RO water. No Nutes in the water so far. When transplanted I added a teaspoon of root microbes. Everything looks good and the green looks lively. Issue is there are few and subtle yellow spots. Not crowding. 1 or two on random plants.

Magnesium deficiency?I think I may have an early deficiency of magnesium? I'm totally guessing here. Not much experience. Seems to slowly be getting more pronounced. First water since transplant to FFOF was only pure RO. Thinking maybe I should added cal-mag?

Why are my plants leaves so bright green/yellow?Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!
