Colloidal silver used problem

Left it too late and are now damaging the (female) plant. You need to start spraying as soon as the first pre-flower emerges.......when flowering has started properly already, is too late.

I reversed a female before to pollinate others. it worked out well. but I don't think mine was 40ppm it was closer to 10. STS works better and easier. growdiaries.com/diaries/129779-grow-journal-by-m0use As long as your spraying the section fully and not doing so in full sun it should be ok. Are your sure the solution your spraying is just 40ppm silver? there is nothing else in it? Might need to fix the medium and excess nutrient solution as it looks to be burning the plant, and the silver solution should not hurt it unless it being done in full sun. Good Luck!

It looks like the spray may have burnt the plant or the plant is suffering from too much nitrogen, either way, this is not normal.

And of course, I apply this spraying to a female plant whose pistils have emerged for male pollen ball production.
