Stinky im in a similar situation...

I have an AK47 x Lowryder growing right now in the 3rd week of veg...She was in Miracle Organic potting mix (which killed my other 4) and I just transplanted her in some Promix BX as it just arrived in the mail...I can see that the tips are beginning to burn (prolly nute burn from the MG)..but how many days should I wait until I start using the Botanicare Pure Blend Pro soil Form?

It's in a 3'x1'x3' cabinet with a 400w MH/HPS bulb at around 83degrees....20/4 light cause its autoflowering
