questions about nutrients

i posted this in the general section and no one responded so i thought id place this in the correct section


ok let me start off by saying this is my first grow....my plants are around 2 months of vegging and ive been using miracle grow as fertilizer i think the NPK level is around 27-14-9 or something like that i dont have it in front of me......anyway im hoping to start flowering within the next week or so and was wondering if i should flush out the nutrients before flowering and switching nutes or is it ok to just switch the nutrients.....also i found some blooming nutes in my garage that are 9-59-9 is this adequate for flowering or should i look for something with more potassium????.....i dont have a problem with spending a lil cash on some bloom burst or whatever nutrients you people use....any suggestions on what nutrients you use for flowering or methods of flushing would be awesome.

thanks in advance guys

You don't need to flush between veg and flush as the plants will use the extra nitrogen in the first 2-3 weeks of flowering when they put on their stretch. Plants will grow 1/3 to double the height when the lights are flipped back to 12/12.

The flowering nute you mention above would be good for weeks 5-7 when the plants need extra phosphorus to bulk out the bud. But I think in weeks 2-5 of flowering you would do better useing something like [SIZE=-1]Peters Bloom Booster Soluble 10-30-20.[/SIZE]

thanks man you are a savior...
