Brown Patches On Leaf

[Mañ'O'Green]

Ok, I had to look up LITFA......!
Yes, I started your schedule. I fed her a full dose on the 30th. I mixed 32ml of Micro Grow Bloom, then 16ml of Voodoo Juice & Carboload (in that order) in 8 liters of water & watered until I got 10% runoff that I ph'd & it was 6.5. They looked really good until this morning.
As the pots are already nearly empty, I had plans to give each of them 4 liters of plain water with runoff either this evening or definitely tomorrow & the next feed, per schedule.
So you're saying just buy Epsom Salts & give her that? I read a tablespoon per liter of water? And I assume give it to her in a liter or two of water after I give her 4 liters of plain water or in the 4 liters?
As I said, the calcium in my water stains the draining board metal, kettle, toilet bowl, literally anything that it touches for an extended period.
Any harm giving it to the other girl before she shows any problems?
Here they both are today

Don't water your plants by amounts on a schedule.

Water them when the pot tells you it is time. That can even be multiple times a day with a big rapidly growing plant. What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and the roots and microbes will die there. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don't let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water water the entire pot. How to learn when to water starts before you plant the seed. Fill your container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds (half of the water weight) it is time to water again. Slowly wet ALL of the soil until run-off begins. There is an art to watering.

I have been testing it's weight everyday since I gave it a full dose watering, so it's why i was guessing they needed a watering soon. Right now they both feel just less than half full.
So hopefully my final question is, as I expected to feed them just 6.5 ph water tomorrow, & if the plants need magnesium asap, when do I give it to them? After giving them the plain water, or with the water?
