White residue on leaves

This just keeps coming back, at first I thought it was from foliar feeding, then I stopped and it kept growing on newer growth that had never been foliar fed. Help? Temps are Low: 70 High: 86 Humidity Low: 16% High: 30% FFOF Soil. Link in my sig to grow. Nutes are Super Bloom and Molasses.

It's not pretty.

HEY I'm having that same thing happen and I've been wondering what it is. Can we get an answer please?!

i had the same thing happen to my plants, assumed it was mildew and treated accordingly

If you are spraying your plants with anything its probably just left over residue. For example, if you mist your plant with hard water or nute water. Hard water will leave behind salt traces which are visible as white dust. Heavy nutrient mixtures (for foilar feeding) will leave excess residue behind. It doesn't look like powdery mildew, then again i can't enlarge your pictures because of my slow internet. Your leaves look twisted as from a pH imbalance, shift, or lockout. Your leaves also look dark green and nitrogen overdosed. If you have any yellow tips that are burnt I would only use water for 2 weeks and continue feeding at 1/2 strength. If your plant does have a pH imbalance the spots may be showing up from leaf deformation.

pH'd water and problem solved. thank you sir.

looks like it might thrips or residue
