    Yes, you are overthinking.
    Keep it simple, and you'll have fewer problems.
    Right now in DWC my ppm is 450, which is about 400 MC and 50 CalMag.
    Slowly going above that started nute burn (orange leaf tips, clawing) , so I backed off.

    There are two things to watch out for when not overfeeding:
    Be on the lookout for CalMag need.
    If leaves start getting light green, increase feed.

    There is some sensitive strains out there my man as you probably already know. A smaller indica type Auto would take less. A auto blueberry dominant strain takes less feed I have personally found that out. If I was growing 24 c by Mephisto I would keep it down on strength.

    Im going to start just going with base nutes all the way through and then adding the BE as it says. If my ppm is too high I’ll add some RO water to bring it down within range that way I’m still using the PK boost just not at a ppm in which is still too concentrated to burn. Lessons were definitely learned. It was my first auto grow, first time in coco, and first time using MC. I’m going to yield roughly 3-4 ozs on 3 plants that were in two gallon pots.

    I do not add pk booster slash bud booster only when the buds start and form I do not use from day one or during veg stage. I just grew this auto purple gorilla by short stuff seeds. You cannot go wrong not using it you will still grow wicked herbs and get weight. It just happens to work in my garden. This plant is a good size

    For hemp/cannabis, the required P/K ratios are usually 1:2 or higher, so that is how we have our PK Boost setup (to meet Cannabis/Hemp needs).
    Other PK boost, like 1:1 type ratio, are more generalized PK booster, that might work on any hydroponic crop, or, have higher P to make up for some other weakness in their feeding charts. So for example, say a multi-part nutrient formula provides less than required P for Cannabis, so having the PK boost is required to balance the P higher to an acceptable range. This is one of the big problems with multi-part feeding nutrients, they basically take a complete formula and break it into 5-10 different puzzle pieces to help generate more revenue.

    Mega Crop is designed to be a complete standalone nutrient product for Cannabis/Hemp, however growers might still need to make small tweaks depending on genetics, plant phase, or whatever their preference. In this case they can use Bud Explosion PK boost to boost PK, or CalMag to boost N/Ca/Mg.

    Also, in a few months we will be doing a very slight refresh to Mega Crop formula. Won't be a large charge, but we are boosting Calcium more, and Magnesium even a bit more, and also most likely adding in Fulvic/Humic acids as well.

    I love the 2.0 but I do believe you know exactly what you are doing. You seem like the kind of company striving for the perfect all in one. Keep up the good work.

    I'm only on my 2nd grow -- and have yet to have a lush green plant in veg. But... I fed my flowering girls a couple times with that 1.8EC and they started greening up (better late than never, lol). But I got some burnt tips. So I diluted it 20%. We shall see. I'd like to get a baseline nailed down that I can just tweak.

    It seems like most people are either in the ~500ppm camp, or the 4-5g/gallon camp.

    When people multi-feed, do you typically run weaker nutrients more often? Or the same nutrients more often?

    I fully agree with your approach -- constantly upgrade your product, particularly based on feeback from growers of all types, including autoflowers. Perhaps, even consider aligning your marketing to more outright claim being innovative, the product constantly tweeked, science- and real world evidence-based improvements, etc.

    I do know with the amount of nutrients you stated above the ppm is close to 620. Is your meter calibrated? I don't think this mix is super strong but I do believe you have to much MAG that could cause issues. Drop the CMP for sure.You can get CAL from the MegaCrop. The BE is very concentrated can push ppms higher with ease..

    Recently Calibrated both ph and TDS. ph was within 0.1 pre calibrate. tds was within 20-30 ppm pre-calibrate.

    Will double check next batch, but I've been simply running the same amounts with +1 gallon. Going to start multifeeding soon, my 2g fabric pots are fairly light at 24h.
