How often to feed

If you are using FFOF, that soil runs hot/rich, if you have not noticed. I believe and have followed this routine for many grows - - - - - > Do not feed anything for at least 30 days. If you have a strain that is proven to drink up nutes, then I would start at 50% strength, after the 30 day mark. For strains sensitive to nutes, I would feed after 6 weeks, at 50%. I feed every third watering(every 10 days or so), due to the residual micro-nutrients, still in the soil. I have over-fed my plants more than once, with this soil. So be careful, with those liquid nutes. Good growing.
