Does anyone know if I should add additional nutrients during flowering if I have used Miracle Grow Soil (with time released nutrients). I know its not the best option, but its too late to change it and the plant seems to be doing well. I would like to switch it over to flowering soon and read that I should only add additional nutrients that do not contain nitrogen.

Heres what the post said:
"If You Used MG soil, do NOT nute at all during veg... and use only additional P-K and suppliments without "N" during bloom..."

Any thoughts of how much P-K to add?

There is no set time for when to add nutrients. If your plant seems to be doing fine, no deficiencies ect, then I wouldn't touch it. If you feel you must really add nutrients, then add a VERY small percentage of what they actually recommend and see how it responds. I'm no miracle grow expert, but my bag shows a very small amount of any "time release" nutrients.

All in all, just play it by how your plant responds. Yellowing of leaves, nitrogen deficiency, add nutes with more nitrogen. Browning of leaves and slow bud production, add phosphorus nutes. A deficiency is easier to fix when noticed quickly, then an abundance. So let the plant tell you what it needs.

I grow with MG, when flowering I use Fox Farms Big Bud and Tiger Bloom. 1/4 strength than go from there.

I had used that same soil a few years ago and it was fine but the nutrients in the soil never made it through a complete cycle. What I would recommend is when you flip the lights to 12 start with a weak 0-10-10 such as Alaskan Morebloom (You can pick it up at Home Depot for $5) and watch for deficiencies. I think I needed to add a little N fertilizer a little later in the cycle, but not much.Good luck!
