Curling leaves, brown spots

[MeefChief]

I'm wondering if I'm showing signs of nitrogen overdose, or is this a calcium deficiency? Should I flush my soil and start with a light feed again?

Meef. All in all nice healthy plant. I say light feed. Might just give good water and cal/mg one day and then start increasing dose of flower nutes--like you mentioned.

I have grown similar looking plants (often). Curled leaves and cal/ng looking def.

Does look as if had a rich diet with plenty of N. Rusty edges likely just a one off burn and/or lock out. Yes--maybe cal mag for they lock out easily.

Showing color in buds so it is nearing time to ripen.

Personally--I would not do a big time flush in this stage of flowering.

Rather would just check PH often and adjust if overflow off or shows more visible indicators like you are seeing now.

I would just baby her thru the grow.

Cheers

...GCase, thanks brudda! ..... Meef'-- I think you have one because of the other! There's N-toxicity for sure, with those down-curled tips, and in some cases, Ca availability can be compromised,... we still need the basic info bro'-- grow method, relevant products used, pH of media used,... for sure, ease way off the N inputs for a bit, as for adding more Ca-Mg or not, and flushing, let's see what the pH is first,...

I'm growing in Happy Frog soil and using AN pH perfect base nutrients. pH has always been around 6.6

When she started showing signs, she was being fed

Sensi Bloom A @ 2mL per L
Sensi Bloom B @ 2mL per L
B52 @ 2mL per L
Overdrive @ 2mL per L
Bud Candy @ 2mL per L
Bud Factor X @ 2mL per L
Sensi Cal/Mag @ 1mL per L


Since everything has happened, I cut all of my nutrients back to 1mL per L.

What happened over night.

Meef didn't you at one point say you were doing like 5ml per liter? Or was it two the whole time? Do you ever foliar feed? She'll turn out alright. It's kinda like sex. Or pizza.. even when it's bad it's still pretty good.

 

[MeefChief]

I maxed out at 2mL per L, but have recently backed it off.

Hey Meef I thing that you original diagnosis was spot on.
The the dark color and curly leaves, typical signs of N overdose, and the ugly looking spots on the leaves that Ca def ....
Autos don't tolerate usually the full recommended dosage of nuts, every time you feed, you need to cut it in half per litre of water and you will be golden ...
