Powdery Mildew?

[Sampas92]

Hi guys, this white stuff on my clone is PM?

Better trash it right?

That looks like it. Sometimes dissolved solids in nutrient solution or foliar sprays will remain as a deposit after the water evaporates. To be sure, wipe it off and if it comes back in a day or two, it is Powdery Mildew. You can clear it up with Safegro's Mildew Cure. Armor Si from General Hydroponics also bolsters against PM.

Thanks fletch
I was thinking about salt build up or mildew because i have sprayed it before it shows it.
I gonna wipe it like you said and see what happens.

In terms of environment in the grow the way might be not many harsh swings in temp and rh?what can i do in terms of environment?

Peace

Increasing air movement always helps. You can also lower your Relative Humidity, especially during the Dark phase to make things less conducive to Fungal growth.

Happy Growing, and Best of Luck!!
