This is a flowering mix - that is, it is intended for plants or clones that will be flowered. The mix has enough nitrogen to get through a couple of weeks of vegging and the stretch. The grower may need to supplement nitrogen, watch for yellow leaves before 5 weeks of flowering.
The basic mix is
40% castings
30% perlite
30% vermiculite
For each gallon of soil mix, add:
1/4 cup of high N guano
1/2 cup of high P guano
1/4 cup of dolomite lime
1/4 cup of kelp meal
The problem with high nitrogen guano is its variability. Different guanos break down differently and may burn your plants diffferently. The upside is that high N breaks down quickly and is used by the plant immediately, so that the grower can determine how much is too much pretty easily. Burned tips are just pushing the envelope, but a ram's horn leaf curl indicates way too much nitrogen.
Conversely, high phosphorous guano breaks down slowly. It needs to be supplemented early with an organic flowering fertilizer, like EarthJuice bloom.
When the plants are potted, water them in with a mix containing 1 tbsp each of EarthJuice Catalyst and Maxicrop Liquid Seaweed per gallon of water. If the grower uses B'cuzz, then by all means add it as well. Thereafter, use EarthJuice/Maxicrop, every third watering. Make sure that the plants are fed bloom fertilizer until the fourth week of flowering.
