looks like calcium and magnesium def to me, but to confirm
whats the medium?
what fertilizer brand? is it liquid or powder, organic or water soluble?
do you have calmag?
provide picture of entire plant
what size pot are they in?
they look both calcium and magnesium def
id spray with 1/2 tsp Epsom salt per gallon every 3 days 3x
top dress 1 x with 1/2 tsp Epsom salt
id start watering in 4mls calmag and 1/4 tsp Epsom salt every other watering moving foward
ok hold offWhat about a foliar spray i have its 31% cal
is it 31% or 3.1%??
does it say what its derived from?
what else is in it aside from calcium
does it say its organic?
is it a dry powder or liquid?
the other option is to weigh 32 grams in 1 liter warm water to build a concentrate
let it fully dissolve
then cut it 1 oz per gallon then add 1/2 tsp epsom salt and spray
but you need to figure out how to get your calcium up in your root zone and this product is just to strong to use on the regular..youd be safer/better off with some liquid calmag
