Miriacle Grow Potting Mix w/ Time Released Fertilizer

So I have Miracle Grow Potting Mix that says it feeds plants up to 3 months.



I also have Miracle grow all purpose fertilizer.




So my question is, When should I start putting on the fertilizer? I know it says 3 months, but I just want some solid advice.

Should I use half strength? full strength? what? when?

Don't use miracle grow!!! You can get some real nutes and soiless mix for less than $60. Probably less.

Too bad, already bought it.

Return it.

im using miracle grow didnt need to add any nutes till around 30 days into my grow about the nutes that nute lowers your ph a bit so ull need a good ph meter to work with it im using miracle grow organic choice and says the same about feeds for a bit but im sold on miracle grow it realy works out nicly just monitor the ph when its time for nutes oh and go real easy on it they are really strong
