Whats wrong with my autos :(

[speed420]

Hey guys looking for some help!! So here is the run down of what i am useing. I am useing the autopot system and a 630watt cmh light in a 4x4 tent. My 2 plants are flowering now and was all good untell a few days ago!

I have just switched from a LED to a cmh about 6 days ago now. I have the mats copper side down. I am using the clay balls in the bottom with a air dome and then coco/pl mix. Here is some pics of whats going on with my leaves and my 1 plant is wilted.

I just did a big flush on them with ph water and letting them set in the trays with no water in them to let them dry out abit. I did notice the last few days the pots seemed alot heavier could this maybe be over watered? Also I see on both of my pots some of the roots are hanging out of the bottom of the pot.

This seems to be spreading on both plants and starting to attack all the leaves.

Thanks!!

Anyone?

At first glance it seems really random in where it's popping up - do you notice it more on the lower or upper leaves? Does it spread to the entire leaf or just kill off the affected lobe?

Something that just randomly pops up with no discernable pattern might indicate a pest or pathogen.

Nutrient or light or water issues typically systematically work their way up or down a plant.

What's the temp in the tent?

Thanks for the reply. It seems to be more on the lower leaves. It is spreading to the whole leaf then they curl up and get crunchy. The tent runs 70/75F

hows your air circulation

Looks like there could be multiple issues at play. What is the ph in the res? What nutes are you using and how much? Did you flush using the res? It looks like some sort of lock out from here, but a little more info is needed to guesstimate

I have a 20x20 inch fan blowing cool air into the tent and a 6 inch inline fan with filter for exhaust.

ph of the res is 5.8. I am using advanced nutrients ph perfect grow/micro/bloom.

Are you a tobacco smoker? That looks a little like Tobacco Mosaic Virus.

Disregard my info as I got it backward you switched from LED to CMH not the other way around

were you feeding differently for LED such as extra calmag or anything?
cause the plant will have different requirements for each light
