Burned upper leaf edgesHi!
Dark spots appeared on some upper leaves overnight.
I don't think this is the cause, but I did a pretty heavy defoliation the day before.
the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish.
what could this be?Week 5

When should I put the pellet in the 5 gal pot??I am currently growing a tangie'matic with "a pot for pot" grow kit. At first the seed germinates in a pellet. Then it says "put pellet in 5 gal soil mix after 10 days or when the third set of leaves matches the second." I did it after 10 days and this happened.Leaves. Curl down

What is causing my leaves to turn dark and dry?I'm growing 3 Gelato #33 plants in a DWC 5 G bucket setup. Same conditions for all 3 plants, but one of them is experiencing dark spots on the leaves and now they are beginning to shrivel up and dry out. The newer growth looks okay, but might not last long. What can I do ?6y ago

Flush or what to do ?Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?3y ago

Brown spots on leavesWhat 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?

K deficiency? Or something else?Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?Week 9

Leaves problemsCan you please help me ? This little one is week 9, but seem to have a lot of trouble :(
Also, I can't find the perfect watering spot. It's indoor with 18L pot, but if I'm watering more that 1L each 3 days, it's wet all the time. How can I do ?
Thanks a lotLeaves. Color - Dark-brown
