hi , im in rockwool my plants are 1 month old and they have 2-3 sets of true leaves
i noticed what i think it is a iron/cal/mag deficiency so i bought some epsom salts and calcium carbonate
i have a foliar spray to which i added 30 ml dutch master liquid light +30 ml penetrator + 1tsp epsom salt +1tsp calcium carbonate , i spray every 2 days
on the dutch master site it says the ph of the foliar spray will be at a ph of 8-9
if i added epsom salts and calcium carbonate should i check ph of the foliar spray
for root feeding i added 1 ml Grow A + 1 ml Grow B +1 tsp epsom salts + 0.5 ml Zone + 1ml Max Grow + 0.5 ml Silica and how much calcium carbonate should i add?

Always check the pH of your water it is extremely important for plants the only way that the plant will absorb nutrients. If the pH is too high or too low the plant will lock out all nutrients ph should always be 5.8 and 6.5 i always set 6.3. PH of 8 to 9 is way too high. Even if you just sprained it on the leaves. I would always set my pH to 6.3. Also are you watering them with different jugs of water? because some of them look fine and others look like they have possible nutrient deficiencies. I would always mix all my nutrients in one jug and then split them up between different jugs for easy of water. That way you're sure that all plants are getting the exact same pH level and nutrients. It also looks kind of like a nitrogen deficiency. But if what you were doing is working stick with it.
