Looking great so far. Nutes are usually not added untill the cotyldeon leaves die, like Bekind said, several weeks into the grow, because of the soil and the fact that the cotyldeons have enough food to start the girls off. However I believe you might be able to start off light and work your way up. I do know of a grower that took his video's off the tube he used all Foxfarm, he used full strength in veg. and in bloom started 1/4 and worked his way to 1/2 strength. He also had prime environmental conditions, 5 gallon pots and 600 watt lights were used. Just learn to read your plants and any signs of nute burn, back-off a bit.
