Black dots could be Thrips. Need better pics. They bite the leaves and it turns black

For me ever since I have been growing in soil, I have not watered to run off, seems counterproductive to wash out all the microbe life in the rhizosphere you are trying to embrace using BioBizz. In soil and with using RO water I have not ever had to use CalMag as the minerals found in your soil and tap water should be fine, I personally see no calcium issues. I agree with these folks that could use a mild boost with Nitrogen. Understanding BioBiz a bit more, Bio-Heaven provides the soil with amino acids that allow the plants to uptake nutrients faster, you will find your fulvic and humic acids more in your BioBiz Top-Max, Bio-Grow will have the strongest support to your NPK at 4-3-6. If it were me, I would brew a Compost Tea with the following ingredients. • 5 Gallons RO water • 3 Cups Good Worm Castings (Great Source of Nitrogen) • 2 Tablespoon / 30 ML Molasses (Unsulfured Back Strap Highest Sugar Content – Drives Microbes Crazy) • 2 Tablespoon / 30 ML Fish Fertilizer or if you have it BioBiz Bio-Fish (Great Source of Nitrogen) • 1 Tablespoon / 15 ML Seaweed Fertilizer Put all that into a 5-gallon bucket and aerate with an air pump and air stones for 24 hours, I place this into my tent to make sure it is warm while it aerates so the Microbes grow, water your plants with this, do not dilute it, it will make more than you need so you can cut the recipe in half or water all your house plants. If your soil is depleted (probably is), I would top dress it with a good layer of Worm Castings and continue to feed your plants as you have been, using your current BioBiz regiment but you could double the Grow and Bloom, for a few days. I like to brew a tea at least monthly but recommend for you maybe weekly to replace a BioBiz feeding. Remember less is more with Auto Flowers / your plants are truly doing fine and just need a non-aggressive Quick Nitrogen Boost.
