Plants don't care about fancy pictures on bottles or marketing hype. Boring powdered nutrients are cheap and grow awesome plants.
i am attempting to lower my VPD with a dehumidifier and brought up light intensity. epsom salt in the nutrient solution at a rate of gram per gallon ? or would you recommend foiler spraying at a teaspoon to a tablespoon a gallon ? i appreciate your input ! been trying to find any help with leds and deficiencies and how to correct them for about three weeks. not a lot of shit out there. still new i guess ?
I would never recommend using teaspoons or cups or anything but grams per gallon, or litre or whatever.
Watch some greengene's garden videos on youtube, especially on nutrients, you will learn a lot.
The problem with me telling you how much to use is I don't know how much magnesium you already have in your nutrients.
I know that Megacrop altered their recipe to give it a better amount of magnesium recently.
I add 1 grams per gallon of epsom salt to my old style Megacrop and my ladies are usually happy.
