Hi all, growing 3 bagseed under five 26w CFLs. They're about 30-40 days into flowering. Noticed that they have a textbook mg deficiency and was wondering if adding epsom salts or lime into the water would help. I'm feeding them with PureBlend Bloom Formula at about 3 tbsp. per gallon of water as recommended on the bottle. Should I give them a clean watering and maybe add some of the aforementioned items? Any tips are always appreciated. It's my first time.
