First Timer using MegaCrop

[Buck]

I have been using MegaCrop for about a month now and I really like the product. I have been gradually feeding my plants more and more. I started around 1.5 grams a gallon and now am at 4 gr/gal. I use strait perlite as a medium using the hempy bucket style method. I have 2 different plant that have had strictly megacrop and one of the two has an issue. I am thinking it has to do with some calcium but would like a second opinion as my experience with this product is limited. I would love to dial this in.

Ph goes in 5.8 and drains out 6.2

I would increase the dose a bit, the N levels looks pretty far from being too high, so you can safely increase it!

Im still using the old formula and I only supplement epsom salts. Thats a magnesium deficiency. I know another grower that uses the new formula and it still lacks mg for leds. If you run led, the ppm per gallon, for mg, should be around 40-70 ppm. Some strains like a little more.
The old formula at 4g/gal equals only about 18ppms of mg. The new formula at 4g/gallon is still very low for my liking and its only around 22 ppm per gallon.
Whatever formula youre using, add 1g/gallon of epsom and that will be the low threshold of ppm (for led lighting). Wait a week and if the issue does not go away increase the epsom salts.
I think GLN should make a led version of MC.

I add some CalMagPro when they start to look like that, and it goes away Happy growing

Hey folks i know everybody says u only need Megacrop but sweet candy is so so good for your gals and they’ll love u for adding a little extra to their plates. And there’s magnesium in it to supp for us high powered led users. Plus all the extras.

And it won’t break the bank.

I’ve drastically reduced the amount of CA/mg from GH that I use and have upped the epsom and had no issues. I think the Calmag was just to much calcium and N for the amounts needed to solve my Mg def. So this run MC1 with 1:4 old dose of Old calmag and 1/4 tsp per gallon of epsom every other feed and they have been deficiency free.

Saves me even more money

Thank you all for some very constructive feedback. I do grow under LED's some EB gen 2 strips with a mix of 5000k and 3500k. I am up to 6 grams a gallon and I have noticed the plant is correcting itself. I think adding cal-mag was a wrong choice I made a couple of weeks ago. I think increasing megacrop 2.0 should of been my first step. I like the epson salts as a direct mag correction and will take that into consideration next time. I will be putting in an order for some sweet candy as I wanted a little boost when moving to flower anyway. I can also use it in veg if needed. Thanks again for the suggestions.

The sweet candy is a great idea. I

I'm running some mephistos under QB260s with megacrop 2.0 in coco.. epsom salt has been essential for me. I add either half or full tsp.
