:thumbsup:Thanks for the replys. It is not pollen that is for sure plants has hudge buds on it.

I should have mentioned the plants were in flower right now and have been for 5 weeks. I am getting awesome buds, in spite of the nute burn problem and this white powder.

I will try the mix and spray real well and then when I am finished flowering I will bleach room and repaint, just to be sure get rid of it all.

Does anyone know where it comes from how do I get it in the first place. I keep a very clean shop.

This white powder has not effected the bud production, at least i do not think so.
Will keep you posted.

Thanks: Pay It Forward

sccrocks Reviewed by sccrocks on . White Powder on Leaves :rasta:Good Day :rasta: I am looking after 46 plants that are into 5 week of flower. Using Sunshine# 1, PH 6.3 EC 196. Fert Fish Emolusion. 3 - 1000 HPS. Lots of air in and out. circulatining fan running 24/7. Lights are 12/12 now. The past month I had to deal with a Nute problem fixed with epsom salts. Prior to the nute problem I noticed that at times there was a fine white powder on some of the leaves. I can wipe the powder off the leaves, however it will not wash off with fine spray. Rating: 5
