yep, I sure did

I edited my backwards comment, but just to clarify

Humic is very 'earthy', best for soil.

I’ve been on the Megacrop about a month now in a coco dtw set up. Things are looking great and much better than my veg plants ever did while on the V&B. I do have to use some PH down with it though where as with V&B things always settled at 5.8 with my 70 ppm tap water. I’ve been feeding @ 1.4 EC after adjusting my tap to .2 ec w/epsoms. Should I be concerned about MC’s high N in flower or should I just go with it? I’ve really had great results with V&B in flower and originally planned on using MC strictly in veg and flowering with V&B but the plants look so good I’m questioning myself now.

Although I plan on using Mega all the way through, I got the Red Line and Sweet Candy I just dont know what to with them exactly. Everything is going great with just base I dont want to wreck a good thing.

I'm feeding super low and they look so damn green its great but Im down to 300 - 400 ppms (0.6-0.8ec) with 75ppm starting water.
going into week 6 now so now would be the time to give some PK, if im gonna, right?


***
wanted to add: its a micro grow, coco dtw, 22oz cups ... not growing trees

With an 8 week strain, I hit them at week 6 with a PK booster. 2 weeks of flush and it will be oh so smooth by the time it's done.

Thanks for the tip!

So far my mix looks like:
75ppm source water
75ppm Red Line
75ppm Sweet Candy
175ppm Mega Crop
1/8 tsp Greenleaf Algae extract

400ppm/0.8ec

Here are some interesting specs on Megacrop:

NPK ratio: 2-1-3 is typically used for maturing tomatoes, maximizing bloom output with that ratio. If you bump up K with something like potassium silicate or a bloom booster, it throws the ratio off and you may get a magnesium deficiency.

NO3-:NH4+ ratio: 25:1- The most stable nutrient pH is ~9:1 (Trelease, S.F and Trelease, H.M., 1935, Science 78:438-439) The pH will probably drift up after a few days with Megacrop, but that's normal for hydroponics.

Ca:Mg- 3.4:1- Megacrop is probably suitable for coco at that ratio. Botanicare Cal-Mag Plus is 2:1, which is suitable for hydroculture. 2% magnesium might be a little low, but may be sufficient with chelators.

Si is 1.32 ppm at 455 ppm. If you like strong stems, you may want to invest in monosilicic acid with Megacrop.

Chitosan is one of my favorite biostimulants. When I contacted GLN to ask how much was in it, they said "not much".

Overall, I think it's a great all purpose nutrient for the price.

Thanks to the crew at Megacrop for sending my samples!

Going to integrate this nest week in my runs.
