In the MG 6 month soil, .06% of the nitrogen is for immediate release. The rest is supposed to be slowly released every time you water, one layer at a time, at a basically balanced NPK rate. (MG isn't very clear on this in their response e-mails) For this reason, I flush very well before use. (clears-out most of the immediate-release nitrogen)

Heat and overwatering can screw that all up though. Not a perfect science, but good enough if you can keep from overdosing them via additional nutrients and crap. No additional nutrients needed during the vegetative stage, but you'll want a good source of micronutrients, like molasses or a micronutrient additive product for proper growth.

It's not necessarily the soil, or the plant's ability to deal with the soil. It could well be you haven't found the right combination of nutrients, watering, flushing, patience and avoiding overdosing them. As with any soil or medium, it takes some getting used to by the gardener.

These are about one month (perhaps 5 weeks) in MG 6 month potting soil that were just transplanted into 5 gallon nursery containers and switched to flowering. The reason they were in MG in the first place, was that my local nursery closed it's doors during the summer. I have since gotten my old potting soil, which they are in now. Were I still in the MG, I wouldn't have done anything different though. (flush the MG well before final transplant, and transplant a week before switching)

They are between 8" and 14" tall here, but it's a gifted strain I'm getting to know. Also, I did switch them to 12/12 early as a result of a failed SuperSoil experiment, and an idiot future son in law spinning my timer instead of flipping it off like I asked. Amber and I have been without meds for about two weeks as a result of this unfortunate series of events.

Not sure why the yellowing on the one plant, but has since greened back up. Am using my normal Tiger Bloom with no problems. I have stopped using the Big Bloom on 'em though. Only additive they're getting now is molasses at 1/2 tsp per gallon per week. (half my 'normal' dose)
Rusty Trichome Reviewed by Rusty Trichome on . question about new miracle gro soil I used miracle gro all purpose potting soil on my previous grow and yesterday i picked up a bag and noticed that the osmocote has been replaced with a new kind of time released food. The new food is round white/clear balls that vary in size and when you squeeze them a little they pop releasing a clear liquid. Does anyone have any experience with this new miracle gro? it seems as though all the food would be released at one time once the shell of the food disolves. Rating: 5
