white fuzz on leaf

I am a new grower .Im in my 3week of veg and i see spots of white fuzz.yesterday i increased my ppms from600 to 900.my temp is at 76-80-day 68 to74 night
eb&flow hyd humd at 55 most of time

need to see pictures

sounds like mold... do u have fans circulating air in the grow? pictures would help

unless your talking about the crystals.. these form with any respectable marijuana strain..

probably powdery mildew had it happen to me need to carefully remove the leaves with it, be careful not to let any of it sprinkle on to the other leaves .cuz itll spread like a mother f@#$*@

thanks i did that and i got some fungal spray but i didnt use it wet

yes u were helpfull i dont know how to give u rep

i hope this is the pic i wanted not good at this

you should prob use the spray before you go in to flower, but a soon as you spray them fan dry them and put the light a little further till the dry. if you have anymore questions feel free to send me a message.good luck and happy harvest.

Take the plant out of your tray and spray the plant with a organic product call Green light. It a pesticide that will also help with spidermites. It'll take care of your leaf mildew in one shot. After that put in another exhaust fan to help with moisture control.

thanks trying to post pics cant fig out

Your plant is looking very yellow. Add some Epsom salt to your nute. Add half teaspoon to one gallon of warm water. Foilar spray five minutes before it goes dark. When light come back on spray with clean fresh water to wash away any nute residue. Do this for two days and It should start looking a little greener.

thanks ill try that .do they sell that at home dep.or do i have to get that at hyd store

you can find Epsom salt at any drug store ie. Walgreens, Long's, Wal-Mart or any store with a pharmacy department. And also Epsom salt has many remedies thatyou can use for. I mainly use it to soak all of my ache and pain with my baths. You can also use it as a laxative. Just trust me when I say "You Cant Go Wrong With Epsom Salt".
