Awesome, don't add any nutes for about the first month and when you finally do go easy, like 1/4 strength because MG soil has a lot of stuff already mixed in the soil. But other than that just let it grow and hope you get 2 or 3 females out of it.
i also use miracle grow soil. i would advise germaniting them in a paper towel. this takes from 7-10 day. after that i would transplant the seedlings into verry airated soil. i found that the soil will become very compact due to the low perlite levels... "it contains none. i would advise buying a bug of cheap pearlite and mixing it with your soil on a 6:4 ratio. the plants love this and will be able to breath alot easyer. i also agree on the nute. by the way if ur stuck with miracle grow plant food during veg may i advise u use 1/2 tbsp mc grow food 1/4 tsp super thrive and 1/4 tsp epsom salt with a dash of calcium chloride. mix this into 1 gal of distilled water "set over night" so the chlorine has time to settle. the first week use half this mix in a gal of water. this way the other mixes counter act the bad stuff in the plant food. pick up some simple ph test strips from walmart. "usually in the pool section" and test the water that has ran through your soil.. (waste water) if ph is incorrect add i pinch of ph increaser or decreaser to your water and measure ph over time. this will promote your babys to grow well and addapt to the feeding regiment. happy smoking. theres other foods out there but this is what i use durring veg cycle ONLY when more expensive nutes are out of the budget. before flower flush for a week with regular water.
