Magnesium deficiency?
Dr_Nowzaradanstarted grow question 5y ago
Could it be magnesium deficiency or something else? I'm already using biobizz cal-mag with the suggested dose.

I don't think it's magnesium problem. Also not a calcium problem. Is it a lower leaf and has your pH been on point.

Just had a look at your diary. Have you got plenty of drainage because you plant looks a little over watered. Make sure you get run off when u water.

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?Leaves. Curl up

Light yellowing leavesSome light yellowing on the leaves, more on the smaller nodes towards the middle. Could this be related to my accidental topping, or possibly due to uneven watering? It was very bushy when i tried to water it last, so i am not sure how evenly the soil was saturated.Week 5

Leaf diagnosis: nutrient burn or deficiency (or both)?he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopyLeaves. Edges burnt
