these plants are in 100% organic soils. I plant with layers and spikes for the most part and i find the plants really like it.. my mixtures include the following either in the base mix or in spikes/layers in the pots..
reused cococoir mix, mushroom compost, worm castings, peat, sheep manure, fox farms peace of mind all purpose 5-5-5, dolomite lime, greensand, bat guano (high P), blood and bone meal, fox farms marine cuisine, diamond black, rare earth, myke brand mycorrhizae on compost, crushed oyster shells, coffee grounds....
these are all under the same 430W enhanced spectrum HPS light, my one and only HID. They are vegged under 4 x 23W CFLs. .
Watered with strictly Reverse Osmosis water. These plants havent gotten anything BUT pure RO water since their transplant to their 3 - 4 gallon flowering pots. The WWx SEAS (White Widow x SouthEast Asian Sativa) did get one dose of molasses with its second last watering.
