Brown spots

JERgardenstarted grow question 6y ago

What are these brown spots? Calcium deficiency? Underfeeding? Appreciate any help. She is 25 days old. Runoff ph is 7.1 and runoff ph is 1.0 ms. Water her every 4 days. I let the soil dry until next watering, but she continously show signs of overwatwering.

What gmslave said but maybe perelite (think I spelled wrong) with or instead of the extra peat. Just my 2 cents, but I coco grow so maybe peats better for the application.??

Thanks gmslave. I have completed a few growths with this temperature, and currently this girl is with other 4 plants (included one plant of the same strain) that arent showing that brown spots. The soil has a good drainage, it has 30% coco coir and 20%perlite.

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Brown spots on leaves What seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue? Is there a fix to this? I grow in soil and the plant is 4-5 weeks old. Thanks for help!

Dark purple areas on leaves — genes or environment/feeding problem?What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

Deformed, very thin leaves Almost all new leaves are extremely thin on base. On some nodes only 1 finger is developed. Some new leaves curl down like claws. I suppose these leaves developed from baby leaves burned by alcohol spray week ago. But maybe it is smthg else? Should I maybe cut them off?

Brown spots watering in coco multiple times a day Seeing brown spots on the leaves. Assuming it's a calcium deficiency. Added another ml/gal of Cal-Mag for the daily feeding. Besides that, what else could it be? Also, at what point do you water plants in coco twice a day?
