yeah go easy on neem, I once top dressed with ewc and neem cake mixed together to help with pests, it was a long long time ago but I still remember its the only time my weed was ever harsh to smoke I have been using neem cake in SMALL amounts in my soil mixes ever since, no neem oil, no neem top dresses ... just enough that it is in there because it is known to improve quality of flowers in horticulture in general so I do like my plants to have a little bit of it... anyway, its easy to get carried away, but whether its liquid seaweed, guano, alfalfa, etc, too much of any one thing is never good regardless of how beneficial the product can be.
