mold/mildew problem???

[SoHigh420]

i have a problem ive been noticing a couple days after i water.
when the top of the soil starts to get a little dry, theres a thin layer of what looks like white powder.
i think it may be mold but im not 100%
i tried taking pictures but you cant really see it that well cuz the camera sux:(
the temps in my room stay around 84-86 and i know thats great temps for mold to grow.
is there anything i can do to stop this? if it isnt mold, what is it?
its only on the top of the soil and when i rub my finger across it it disappears.
ive been noticing that one of the tips of a leaf is dark green and crunchy.
no idea if this is related or if im just having really bad luck with my first grow...

someone PLEASE help me

what is the humidity? my guess is that its mall amounts of dried up salts from the nutes crusting on top, if it was mold i dont believe it would show up only after it got dry. this could be a sign of build up and you may need a flush, tho i am not the most experienced, i notice it on almost all my house plants after a certain while. hope that helped

One part Hydrogen Peroxide to three parts water. Wet plants down good with a spray bottle or sprayer. May take a couple of treatments. If you're indoor cover the tops of the growing medium with aluminum foil after treating and fixing. :thumbsup:

the humidity hovers anywhere from 40-50%
i have only fed them nutes once since ive transplanted them.
ill give them a nice flush within the next couple of days.
thanx for the help bro

you have the weed herpes bro:mad: Powerdy Mildew... these are all bandaids at best you need a systemic herbicide like Eagle 20 EW

I used a mixture of Einstein oil (neem oil) and greencure in the same 32 oz spray bottle of water... held it off for about 10 days.

1 spore is all it takes and you got a problem...make sure you clean your walls floors ceilings ..everything in your grow area with a 1/4 cup bleach to 1 gallon water mix

They do have fungus bombs now too FUNGAFLOR TR....just like the bombs for mites...use the fungus bomb on your grow room....it will be like using a sulfur vaporizer without the smell:D

I would spray your plants top to bottom... you want 100% coverage on your plants.

I havent tried the bomb on plants yet.....so I wont recomend it for use on plants ..yet:hippy:

The soil nutritions is main concern, and your temp is also slightly more, maintain it to 60 to 70 degree Fahrenheit, i think the ph level of your soil is more it should be maintained, water the plant as the ur finger souled go in the soil to 2 inches.
