What def/toxicity do i have :/?

Coco coir hand watered maxigro

Would appreciate any input/advice.

Think it might be because i dont get runoff often and salt buildup locking out my K?

Ill probably flush and rewater with nutrients

Yea def a little hot in there. In coco make sure you get good run off to prevent salt build ups.

Looks like it needs some Calmag and maybe a bit of nitrogen, and keep it cool in there.

How much of what are you feeding and what is your PH?

Ooops yah, its coco fed with little under 1 scoop Maxigro and i dont own a PH meter or ppm meter so i know that doesnt help but generally i havent needed one

I'm thinking that's Mn and Mag burn, which leads to calcium deficiency as well. Dealing with burns are bit more of a task than deficiency's, you gotta transplant or just flush alot.
Also, if your PH is too low or too high it deprives the plant absorbing the right nutrients even if you have them available for your plant.
Get it checked!

(I've used MaxiGro before its great stuff. Too Good. If you know what I mean)

Looks a little clawed, and burnt. Maybe uts just the angle i got m8.

Ph is way out and its root bound in that little pot and moisture stressed. Your ph is too high you have to get it down to about 5.8 for coco.
