Today I spray my pots and clay pebbles, main stalks and basically everything in tent except buds/leaves with neem as a preventive. Depends on stage and reason. This latest grow the clones my mate grew for me had root rot on the tiny roots they had so I spray roots before transplant then spray leaves daily with colloidal nano silver, amazing results. Massive root system quick and the deep dark green of the clones ooozed health. I'm in week 6 of a 8-10week flowering hybrid iced grapefruit and I've been using A.N bud factor X for first time, too tight too pay for crab shells! I mix 2ml of that with 2ml of AN nevana , 1ml diamond Necta and Epsom salt or calmag/iron mix by humbolt secret depending on mg needs. I used to put a drop of super thrive but stopped when I realised the auxins that can be useful in veg slow flowering time and can lessen yield . Late veg/ switch spray is different this time I used AN (freebies) root tribe and foliar sprayed along with enzymes humic acid , salisilic acid and a secret ingredient I always use since discovering that slows stretch and speeds flowering time. Bit of evolution sometimes for recovery but only once a week max. It's strange stuff not sure about it. I often spray after or alternative days between my bud factor X mix and colloidal silver as a preventative of mould mildew as well as general health . Ps normally use RAW yucca as a surfactant but AN nevana has it in as well as Chilean soap bark. I'm new . Hi. Don't hate me
