Hmmmm.... do you think I need to add S to my 5.5g per gallon Megacrop mix?
One?!?! They better do better than that!
I was basing my PC lust on Weas's droopy girls and thinking they wouldn't be a height challenge. I may be very wrong there. We'll see. When I see yours, I think I might be in trouble.
More S will make the smoke sweeter, so it'll boil down to your preference. I find this to be an offputting flavor with the pinene heavy strains. My A Purple for example tastes gross IMO, but it would be too much effort for me to keep making a low S feed for that one plant. The kicker though with using Megacrop, or any brand for that matter is that if you want to change any one thing, you'll have to also change at least one other element. When mixing the whole thing from scratch, you have a lot more freedom as there are no preset PPM levels, but roughly speaking, about 3 different salts I use have a lot of sulfur in them so I get high S regardless.
1 pound harvests was pretty regular in rockwool, and I presume you had the same results in perlite, but now that I'm in peat moss, my weights per plant drasticly went way down. I finally got a decent set of strains that yield well and my feed seems to be right on point, so my chops will be improving starting with the very next one, but I surely don't expect to take a pound from any of them. Regardless of all of that though, I know that ginormous PC will yield the most. I predict roughly a half pound knock on wood!
Edit - You could supplement in more S by making your own CalMag from gypsum (calcium sulfate) and epsom (magnesium sulfate), and add that onto the S that's already in the Mega, and you could hit paydirt.
Edit 2 - scratch that, I just shot
MC@5.5 grams and calmag at 5grams through Hydro Buddy, then tried to achieve the same result, but using gypsum and epsom instead of the calmag, and it took away the needed amount of iron, plus also lowered the N and I think the K. Sure 90+ppm of S would've sweetened up the smoke nice, but that lower N and less than half of the Fe will hinder growth in other ways I'm sure. And this illustrates the frustration when trying to change the levels of a product.
