Miracle Gro Moisture Control

i tried MGMC for my 1st grow - did not get a good result
plant started out nice, then some yellowing appeared in the fan leaves which progressively got worse
never did figure out the trouble
but i do see some have good luck with it, i didn't - i suspect it is not a good beginners soil
I started mine in jiffy seed starter soil mix until they were about 2 inches (2-3 weeks) before moving them. I wouldn't recommend starting a seed in any nute soil, it's too much of a strain, this part of it's life is about making the roots extend and grow strong. Sounds like you got a bit of nute burn.

nope, not burn, started seed in soil and looked fine for about 2 weeks
then color began to leach out from leaves centers, looked like some kind of deficiency, was frustrating
went organic after that, but used MG Organic Soil(with some amendments) - so no hard feelings with MG, just that soil

yeah I actually started another thread at one point where my leaves just came out yellow from the start on 3 consecutive levels, and no one seemed to be able to figure out what it was. It was the most gorgeous yellow plant ever :D fortunately it popped male.

strange. I always assumed it was nutes. Not sure what else they'd be.

Just found this:

Fertilizers

  • Some Miracle-Gro potting soils contain Osmocote fertilizer, which appears as clear, fluid-filled balls, according to company literature

 
I got some the day I put up the first post, and swapped a few AF's that weren't doing to well into it at a ration of 2:1 with perilite. All signs of nute burn stopped, and the plants REALLY took off. This is the same strain I started another thread on that the 3rd set of leaves I had problems with growing in yellow, the G13 AF that they stopped selling for a while. It's not the normal AF easy grow. The nute ratio is really good though, I flushed it once before adding the plant and will continue to use a slightly watered down (no pun intended) grow big and big bloom. @previous poster, those little balls I believe are potassium, it's the way to delay them to flowering time. I've never crushed them, and I will state that normal MG I've never had good results. As for it not being a good beginner soil, if you throw some perilite in it, might as well be MG perilite while we're at it since it has the same nute ratio, you may actually be able to grow it without adding nutes. Not that I'd advise it, but I watered 3 party cups with this soil. Put an over watering, and underwatering, and an average watering, and one of plain top soil with perilite as a control. The over watering drained about as much as the control, the average watering held it all, and the underwatering obviously held it all. 2 days later, using the moisture meter that was recommended, the 3 MG's had almost the same moisture level and were all 3 about the same as the control, so the moisture control actually does work. I'm going to see how long I can go before they go totally dry, will keep up to date.

Again, I hate MG regular. This is by no way an endorsement of their nutes or regular soil. This is just the moisture control, which I have found to be a very forgiving soil and with the mositure control, if I do get nute burn I know I can flush the hell out of it and give it an extra day to recover because of the stored water.
I'm working with the same question of over watering. I'm using MGMC for my grow and can never tell if I should really be watering. A lot of people tell me I am over watering, and I have lost many fan leaves from the bottom up. I am on day 9 now with no water, longest I've ever gone with no water at all. Moisture meter is reading 4.5 out of 10 for moisture readings... cheap one though. I'm about to go ahead and actually flush her for the first time since I've started the lady. 7 weeks using, so I'm thinking my issue maaay be lack of flush. But if the 9 day "no water" stretch helps my issue, I will be sure to update. Figuring out this moisture control isn't fun. 2 weeks into flower pics:
