Alien OG, OG Kush, Rosetta Stone and Mot

3/11 mix water with potassium silicate and 3.5cc's of FPJ in one gallon pH. 6.3 3/15 AM I noticed interveinal chlorosis and brown spots on a few leaves of OG Kush. I think it is Mg deficiency. My foliar spray has half tsp/liter of MgSo4(Epson salt). I added 1 tsp MgSo4, 1 tsp FF Grow Big, 1 Tbsp FF Big Bloom and Corn Seed Sprout Tea to gallon of water and watered all plants. OG Kush got about 1 liter. Should I add more Epson salt to a solution for OG Kush. I am wondering if there is too much Ca++ which can be antagonistic to MG. I have gypsum in the soil along with crab meal and bone meal. All of which has a bunch of phosphorus and calcium. Maybe too much? 3/15 PM Convinced it was a K+ deficiency and not a Mg deficiency. Topped dressed w 1 tbsp Dr Earth Premium Gold, Alfalfa Meal and Kelp meal Mixed 1 tbsp wood ash in a gallon of water 3/16 AM watered w wood ash water mixed with Silicate (@55ppm of Silicate in .5L for OG KUSH) also added Tbsp molasses and EWC 1/2 cup to gallon. Ordered K+So4. Not sure of application. I have seen between 1/16 tsp to 2 Tbsp. I will add to gallon of water @ 30-40ppm and see how what quantity that is. OG Kush is also closest to heater, This may use up more K+ due to increased perspiration and more stomata openings. My Rosetta Stone showed signs of heat stress in this position and I exchanged it w OG Kush a few weeks ago. Switched plants around now we will see how MOTA Hara does near the heater added 1/4 teaspoon of potassium sulfate to 1 gallon of water that increase PPM about 43 3/17 pm plants with droopy and thirsty watered them. Also did a foliar spray. I don't think they like that. It still had some Epsom salt in it and potassium silicate the new growth was twisty added 1/4 teaspoon of potassium sulfate to 1 gallon of water that increase PPM about 433/17 pm plants were droopy and thirsty. watered them. Also did a foliar spray. I don't think they like that. It still had some Epsom salt in it and potassium silicate the new growth was twist. OG Kush got very droopy probably over watered. Maybe it's not perspiring great due to deficiency. For next watering I upped the potassium sulfate 3/8 tsp /gallon. My rational is that 43 ppm is only about 50% K so still may be under feeding it especially with a deficiency. Deficiency seemed to slowly progress but new growth seemed decent.Twisty new growth was better this morning
