small black spots on one leaf

[cdd10]

What could this be...read it might be root rot but I've only watered when the pot gets dry...hasn't shown any signs of overwatering...don't see any bugs..hm..

 

[Southerner]

Do they look like rust spots? Might need a touch of calmag. Overall I'd say its a pretty healthy plant...

 

[cdd10]

Nope not rust spots they are black tiny spots doesn't look like any rust spot I looked up hm...

 

[cdd10]

I'll try and get a better pic, could it be mites?

i dont think its thrips if its thrips youd see more like they eat the inner leaf and leave the skeleton of the leaf. pretty odd man hope you figure it out. oh and youll see little mini larvae that are kinda like baby ass grains of rice but on top of the leaf.

Probably Calcium deficiency.

 

[cdd10]

I haven't added any cal mag whole grow you might be right

 

[Mr Roboto]

it could be just water droplets that forms during lights off and got a lil hps burn from the light turning on. Is it only on that leaf?

It's on three leaves and I'm using led two xgs 190 could that still cause it another interesting reply

 

[Mr Roboto]

from your pic I wouldn't worry about it, just snip off the leaf. Also you may want to prune any leaves blocking other bud sights so they can get light and get fat otherwise you got a nice plant there sir

I was thinking about cutting them off but I didn't know and thank you!
