I think I have a fungus problem!!

My plants one strain more so then the other ones has a problem with the leaves getting small brown spots starts on the outer vien edges then it slowly fills into the center vien. The edges turn brown and then the whole leave turns yellow or even greyish white colored after a bit then of course they just dry up and pretty much die off.

I thought maybe I had a nitorgen diffenecy the plants are in a veg state after going through one flowering cycle the plan was to turn them into mothers.

They grow good but cept for the leave problems and today along the top edge of my pot just on the one plant I find two sets of white mushrooms growing! They was not there yesterday sprang up after the dark cycle they are on a 18/6 cycle.

I have no changed pots or soil from when I started just give them nutes about every 4th watering which I water every 2 days. I have new growth but it seems like after about a week the new growth will start to get the spots.

I was going to try some anti fungal on them and no there are no bugs! I made sure I've also been real diligent in pulling off the infected leaves once they yellow.

Not fungus like I thought it was turns out it is spider mites I got some canola oil based insecticide and wet the under side of the leaves good and the top of the soil some and I got a fan blowing on them now.

I rotate every week between 3 diffrent sprays, neems oil, insectisidal soap, and take down spray. Im hoping that no bugs will get use to any kind of spray and die off. So far so good......(fingers crossed)
