Hello,

My plants seem to have white dusty spots on the bottom leaves I think its just residue from the water but wanted to mae sure it was not mildrew.

That looks like water spots to me man. BUT>>What are your temps/humidity looking like? Circulation? And what kind of water are you using?

 

[philipd]

Temps around 85F humidity at 55%. Got a good intake and extractor hooked up too. Water is just tap water and PH is 6.2 - 6.5 constant

That's kinda warm but could be ok with that ventilation. That tap water should sit out for 24 hours before you use it. It probably has chlorine as well as other stuff that city water has(depending on your location) Could also be hard water that can leave buildup. I would try and use different water if you can buy distilled water from the grocery store and see if it happens again.

Cheers for the suggestion. I live in scotland so tap waters usually pretty clean. Temps not an issue is on the warmer side i know but not damaging

I foliar feed with mild feed and mine get a few water spot residue.not to worry.

Yeah I was about to say if you're foliar feeding then it's just a little residue. If there is no discoloring and your ph and all is good I would just keep an eye out and not worry too much.

Will play about and see
