Hey guys, searched for this and didn't find an answer; how long into flower can I use sm-90 as a foliar? I've got fungus gnats and spider mites and I'm worried they're going to multiply before the cycle is over and wreak havoc...
rootfingers said:Dude, i feel your pain. I am 50+ days into flowering on a 70 day cycle and these fungus gnats are driving me fuckin crazy. I don't know what to do. Honestly, if it was spider mites I would use the floramite now and try to knock them out with two applications a few days apart. The gnats are killing me though. I have been using sm-90 in the nutrients but it has had little effect. My sm-90 might be too old (over a year old now) or I may need to ratchet up the dose. I thought about covering the tops of my containers with sand but it seems like such a huge pita (sooo many containers).
I figure to just buy a new bottle of sm-90 and start with that in my nutes. If that doesn't at least keep the buggers from multiplying too crazily I think I will just let them finish out and ditch the coco they are in. Everyday it gets too later to spray.
We were about to use it for early signs of powdery mildew but I cant seem to find an answer if lights should be on/off and if so how long? Can u advise me o. This quest?spray safe..great product..u can use it till week before harvest
