Burned upper leaf edges
Cannapprenticestarted grow question 5y ago
Hi!
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?

your ph is off. to fix you need to do a flush
flush until your run off is at a 6.0
let the pot dry out for a few days.
mix your first feed of nutrients at half of what you use. get the ph where it needs to be things will be fine.
if you can at the first feed try to add kelp. this helps with the stress your plant goes through. use every other feed.
hope that helps

U check ph and ec? They can be the problem of your plants, you can have a bad tap water that cause lockout

Saw this first day of 12/12Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Potential bud rot?My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early?
I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!
