Have you been spraying the plants with any type of foliage spray

Do u use a humidifier with tap water if not check ur plants for mites

Appears as a dust or something like. Alot of plants will start off a little wonky but quickly grow out of it. It appears to be good to me from eye. I’d watch the water temps and the pH of the res real well the res is what will give u issues trying to keep a steady pH

It’s dwc and no spray

Yes I do use tap water for my humidifier I have a ro system tho guess I should be using it for the humidifier as well?

There’s calcium and other minerals dissolved in tap water. Humidifiers that atomize the water leave the minerals in the water. When the tiny droplets evaporate the water’s gone, but the calcium remains and creates white spots / dust / etc. Use RO and you avoid that, as well as any clogging the minerals can do to the humidifier.

Do you let your water sit for 24hr before mixing nutes and pH and using … And how much air do you have going to the buckets

I got my air pump on full blast with an extra hose in the bucket and no I don’t let the water sit for 24 hours I use RO water

Their is allot to learn when it comes to DWC I’ve done it for a few runs I believe you need to do some stuff with the clay pebbles before use … is the water looking like it’s a roaring pot of boiling water let’s see if someone with more experience in that field can help @Jungle maybe :thinking:

Happy to help, but need more details… the below, plus what nutes are you using in what strengths?

(I’m happy with the “it’s calcium in the water carried via the humidifier”, but still…)
