Magnesium deficiency?

[NuttyProfessor]

think i have a little issue going on here , started to notice copper coloured spots

my plants are indoor/ outdoor
coco and compost
Strain greenhouse cheese from green house
unsure of ph as i bought testers that dont work ( have one coming in next day or two )
had few bugs on plants so i sprayed with home made pesticide ( used it before with no problems ) plants were fed seaweed and molasses

got empsoms salt , did foliar spray last night

advice please and thank you

im also thinking Calcium Deficiency

PH really needs to checked first.
Unless I know your PH I won't know what your deficiencies are, what's causing them, etc..

If your PH is too low or too high, Ca and Mg could be present in the soil, but the plant is unable to use them. Then by adding nutrients, you can create a situation where you have too many nutes which can cause nute burn, lock out other nutes, etc..

It's not worth the additional headaches that can potentially be created by guessing the solution to the problem.

Since your PH is spot on, I would definitely agree it's a calcium deficiency. Try mixing the epsom salts into water, as it's water soluble, and feed into the soil. I'm seeing search results suggesting to mix 2 tablespoons per gallon.

yeah many thanks , im having other thoughts now what it could be , my partner added piri piri salt into my chilli power because she lost the lid lol ,i forgot she had done this , i think when i made my pesticide ive burnt them in places (the spots) .

I would go with an actual Cal-Mag supplement rather than epsom (which is magnesium). I have tried epsom on similar problems without much success. Epsom is good for a flush if you have salt buildup.
