First of all, thank you for posting the screenshots of the reports. Super helpful for those of us willing to help with diagnosing issues. Not going to call myself an "expert" by any means, just someone that has experienced issues with this situation in the past. A few things stick out to me...

Works great in organics. Check the thread that GenericEnigma linked you to and study it in depth and you'll find all the answers you seek. However, all that info only applies if your water is hard and is responsible for said pH issues. When I lived in Arizona, I was on well water and the pH...

100% this. Langbeinite will also work. Langbeinite, or K2Mg2(SO4)3 has sulfur in it that has already been broken down into sulfate. The sulfate in Langbeinite will break down the CaCO3 or any other salts causing pH fluctuations. Anyone living near farms/large scale agriculture will notice the...

I'm going based on the assumption the OPs water is hydrophobic due to the question he asked. I very well could be wrong, of course. Even when I completely soak my peat based soils with water prior to transplant, I still find there are "dry pockets" when I harvest the plants if and when I...

With or without SIPs, the best way to water with organics is not all at once. You water just enough to saturate the top layer of the soil of each pot. By the time you've finished doing this with each pot, the water will have saturated enough for you to complete your watering. It is at this...

Back of the Langbeinite bag says 1-2tsp per gallon of soil, once a month. So, I go with 0.5-1tsp per gallon of soil every 2 weeks. Make sure to water it in immediately after applying.

What's your city water look like? Anyway you can find a report of that and post it? Just block out the names to keep things anonymous, of course. It should be easy enough to find. Just do a Google search for "(insert city/town name) water report" and it should pop up on the first page. Tap...

Sounds like you're into Chemistry and more well versed with it than I am? Was hoping someone like you with a better Chem knowledge would chime in, because my understanding and knowledge of it is basic, at best. Cannot agree enough. I didn't post many pH adjusting methods in my wall of text...

Langbeinite is the best thing to use, doesn't have Ca in it, and is a great source of Mg and K. Don't be offput by the 0-0-22 NPK of Langbeinite, use it in small doses because a little goes a long way. Not to mention, the plants will make full use of all that K. It gets even simpler if you're...

Happy to do it. I enjoy writing (maybe a little too much as you'll see from below lol), and this is my way of paying it forward by sharing the information as freely as I received it. Answering questions not only helps the person asking them, but anyone that may be lurkers or from a Google search...

Happy to help! You're pretty spot on with your thinking on compost teas though. Coots was, and still is the man. I learned a ton from reading the threads he posted in on other forums. That said, compost teas were super popular back in the day because not many cannabis growers were making their...

Appreciate that! I'm no expert either, and with how much there is to learn about microbes and living soil, I doubt anyone could be even if they had multiple lifetimes. In fact, there are about one trillion species of microbes on Earth, and 99.999 percent of them have yet to be discovered. All...

I don't mean to sound like a smart ass when I say this, and I very well could be wrong, but couldn't our plants themselves be considered "microbiometers"? The plants we grow are a direct reflection of what is below in our soils. You can get a guesstimate of whether your soil is fungal or...

Hard to say whether smaller or larger bubbles are better, they both provide oxygen for teas. For those that like to do teas, I've always recommended larger stones because they're easier to clean and don't clog as easily. That said, I believe that if one needs to brew a tea with compost then...

How many 1g pots do you have in that 6x2 area? Depending on how many plants you have, this is one of the best ways to grow if you're not concerned with plant counts. Some quick math to consider. 6x2 area = 12sqft In a 12sqft area you could probably fit 4 5g pots, or 12-16 1g pots. Depending...

Peat based soil has a better CEC than Coco does, nearly double in fact. However, coco is infinitely more forgiving when it comes to watering. In fact, many growers starting out with soil often don't get watering practices right and, as a result, never see the benefits of the extra CEC. I...

I've never used Gypsum, personally, however you are remembering correctly. Sulfates help break Calcium Carbonate (CaCO3) down into separate molecules, allowing the Calcium, Carbon, and Oxygen to be absorbed by the plant and/or soil individually. Gypsum happens to be a sulfate and is very...

Using LED or DE lights? Praying leaves is a magnesium issue, they're praying for more magnesium and not more light. Mg deficiencies are common for growers that switch to LED or DE lights with improved light spectrum. This is because the improved light spectrum results in improved photosynthesis...

Go easy on the kelp meal, adding too much leads to more harm than good. I'd add half, then top dress as needed once every 1-2 months. A little goes a long way. Be mindful of your water source and whether or not it has Calcium in it. The Crab Meal, Gypsum, and OSF is loads of Calcium already...

Happy to help, just a guy that's learned a lot the hard way is all. "Heavy" watering is something that was often recommended back in the day for "soil" grows using synthetic nutrients. For peat moss/living soil, watering heavy is not what we want to do. The reason being peat moss itself is...
