Are you using powder or liquid?
If liquid do not use for nutes as there is a large probability of frying your plant. TOO MUCH NITROGEN. That and its not designed for it.
However in the garden the liquid is excellent in soil and should apply every 3 day.:joint::mrgreen:
I work with plants for an occupation. I also grow weed. Never used blood and bone but normally if the plant is already established you would scatter it across the top of the soil and water it in. You would do this about once a week. Read directions on bag.
I have a setup quite similar. I'm using 2 fans for ventilation. One high power wall fan at the base and a toilet fan directly above a 400w son t agro. I find my temp range is consistantly between 21c and 29c.
The fluid I'm using is AgGrow Vegetate. I'm Australian and this is normally aussie specific. Its really good (both for nutes and soil). You can probably find it on the net. Cost $12oz a litre here.:weed:
I'm currently using a combination of NPK blue and half strength hydro liquid on my outdoor plant. I have found the results really good however my plant is a hemaphrodite Sativa
Miracle grow is good. However in the past I have found that a plants taste can become quite rank when MG is all you use. On saying that some of the best plants I've grown were more or less grown only on MG
