Burned upper leaf edges
Cannapprenticestarted grow question 4 years 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

Yellow/Brown/Spotted/Crispy Lower LeavesWhat is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

Browning, curling of Green Crack leavesIs this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

Leaf damage/discolourationThe yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

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 lot
