Supposed to run the master at a 2-2-1. Ive tried everything from 2-2-2, 2-2-1.5, 3-3-2 and it just seems like they suck up too much mag and throws out calcium of potassium uptake. Stick to 2-2–1 and find your happy ec. I find them happy at 2.4 ec but I run co2 so your happy might be 1.4 for all I know
Ive tried it in reservoirs but the silica ends up just settling at the bottom. Might want to try sprinkling some in the pots but if it is insoluble enough to settle out im not sure if it even gets uptaken. Still worth a try to get a comparison get a $10 lb bag
I ended up skipping it this run. But my plants are stupid big lol. Thought they were autos. But my buddy got them mixed up when he sent them so they vegged for 8 weeks
Absolutely, you should be checking and adjusting pH every feeding, especially with a salt-based fertilizer. That being said, if you get more familiar and the pH doesn't change around too much, as long as everything else stays consistent, you can minimize the amount of checks you do. From my experience with masterblend for a grow, I avoided pH adjusting because I got a 6.0 reading on a defective meter at the start, and ended up getting around a 3.5-4 pH runoff when I had what seemed like every single nute deficiency at once.Hi Y'all!
Does Masterblend need to be ph adjusted?
I generally only adjust if I'm adding in monopotassium phosphate, usually balanced with close to equal parts potassium bicarbonate. But otherwise, not generally, it usually comes in around pH @6, so I leave it be. When it looks like it's <5-5.5 I bring it up a tad, unless I've got a reason not to do so. For balancing purpose. I do like keeping things generally on the more acidic side, just not going overboard.Hi Y'all!

They have a hydroponic version and I would assume it would preform the same as the other similar to it like jacks and mega crop.
thanks Professor
I have a small commercial hydroponic greenhouse growing lettuce. I can tell you that even with vegetables the basic mix of the three Master Blend nutrients vary by crop. I am still trying to verify the recipe for cannabis for my own grow using Master Blend and was in fact looking for the link to a grower whose contact info I misplaced. It can be done and yes the numbers look weird to soil cannabis growers- because there is ZERO buffering in the system. But my own first grow proves to me that the numbers must be vastly different somehow- because I can't get anywhere near the EC numbers that people are speaking about without immediate nutrient burn. I know there are details that make a huge difference to experts that are measuring their plants successes in terms of grams but I bristle at spending the huge $$ to buy a liquid blend that suggests I can't mix my own. I know it can be done with Master Blend or Jacks. So I'm looking forward to changing- even in mid stream (or grow! :-))
What lights and medium are you running? From what I'm seeing, Masterblend needs more magnesium in coco under Samsung lm301 LEDs. They seem to like 2-2-2 better. The 2-2-1 works great for veggies tho under LEDs.
Grams?
Probably time for an update. Been messing with masterblend for a few runs. I'm still figuring it out and tweaking each run. Still many more recipes I'd like to try. This run was my best with MB
