How to feed Manganese?

[SamRD]

I got a manganese deficiency and bought manganese to feed them, but it comes with no instructions on dosing. Do you know how should I dose this?

Well, this compound contains about 32% Mn - you shouldn't cross medium Mn-levels of more than 115ppm (parts per million). Given that medium manganese-levels are impossible to detect non-professionally, I'd rather be very cautious with this.
Secondly, this product lacks a chelate, so it may not even be "plant ready". Just do some tests on an isolated plant.
BTW can you show your "Mn-def" plant?

youd be better off giving them seaweed solution, that has a full range of lesser nutes in it

Not sure what to do

I think the spidermites are your greater problem... or, at least, that's what I think I can make out with my rusty eyes...

I think you have something else going on. But without knowing what you've been feeding and how much nobody can offer any help.

Plant's use such small amounts of manganese that it's highly unlikely you have a manganese deficiency.

If you're going by that illustrated chart that's been floating around for years more people make the wrong diagnosis based off of it than anything else.

I have poor resolution with his pick. But aren't those aphids on the leaf segment at 4 O'clock. I see 6 possibles just there.

I don't know if we're looking at the same thing but from the underside showing on the one leaf it does look like something is eating. But I can't tell for sure.

I'm not proficient with the graphics overlays. But the bottom leaf at 4 o clock. Same things. More obvious. Pests regardless. Thanks. Want people to succeed. I may run out one day.

Your plant may also exhibit signs of a manganese deficiency if the pH is too high, or if the plant is getting too much iron.

"Could" also be lacking in calcium from the smaller brown spots.

Pests regardless. Thanks

Bro, address Mn deficiency with a chelated foliar product. Mn will not be a mineral that is easily or rapidly taken up by roots. Also you may have an abundance of Mn already in your substrate but it is unavailable because it is in the wrong form, or you have poor biological activity. Get a soil test don't guess.

You have a few other concerns. Best of luck solving and learning this craft.

very true. tbh there are at least 2 of these charts which seem to show it all wrong. and although nutritent deficiencies may not come isolated, or, in combination, these charts show leaves Ive never seen before (they also did DRAW or PAINT these charts instead of just taking a real pic of an actual hemp plant...)
instead, I find that the typical outlook of N, P, K, Mg & Ca defs one can behold in a number of common household or garden plants do apply for Cannabis much better...

I agree 100% Knowledge of basic plant physiology is much better knowledge than the cannabis broscience that's been floating around for years.

whats up with the pink flowers? what do they look like dry? is that a strain that you can direct me to? i’d like a pink flower to give to my wife. it might even get her off my back for spending so much time with my girls!

That plant was Cherry Bomb from Swami. The amazing color does not carry over to the dried flower. Finished buds are slightly purple-ish, a little wispy and gave an excellent and distinctive retro sativa high.
