COM Stonington Blend, 7 gallon bag, WW photo, HST then SCROG. 18th day of flower, stretching very nicely. Showing signs of manganese deficiency. Using all COM nutes and additives per schedule. What can I use for manganese problem?
Manganese is pretty rare. Likely something else. How about filling out a Support Ticket and attaching photos of the plant?

How much per gallon or top dress?
Soil is looking N depleted as well: top-dress worm castings to stay organic. I second the Epsom Salt.
Never used Epsom. How much do I use?
@sandune I use it at 1 teaspoon / gal water
Thanks everyone, it’s lights out now so I’ll get to it tomorrow. I’ll post pics and notes on the results. Thanks again!
I’m currently growing in COM Stonenington Blend for the first time. Growing autos as well. Previously used Fox Farm OF didn’t have to feed first 4-6 weeks. Was expecting similar results but haven’t. Had to start feeding from the first week. They have done well since. Tons of fungus gnats easily controlled with neem oil and decreased humidity but a pain in the butt.
The fact there are holes worry me, look under your leaves for pests. 1 tsp is a Lil much I’ve found my organic girls love 1/2 tsp once a week but I also feed them a dose of nectar of the gods
Sorry I add mine using a scale @ 1.18 grams / gal
I have found no pests on the plants except gnats. I look 4x weekly with magnifier glass.
