are you leafs getting yellow ?
did you start you flowering nutes after the day you switch ?
Whats your soil ? is it a light soil ?
Depending on the strain , your plants will require large amounts of Nitrogen the first 2 weeks after the switch , because they will create alot of "green" material when they do the strech, and some nutes fail to provide it.
How is the thikness of your stems ? in the new growth ?
But pics would be a great help , or else we are just shooting in the dark.

It is light soil, they were doing great, I think it might be because I never flush the soil, maybe nutrient build up in the soil, I checked the run off yesterday it was at 5.7 ph, and the nutrient was at 3500 ppm, which seems really high.

Looks like wind damage

Besides the extremely high nutes it does look like air burn. I've seen that in a small veg cabinet I run when I had a fixed fan in there. Have yet to see it again since I switched all my rooms to oscillating fans.

Way too high.
Get your PH up a bit too if you can.
You're feeding, but not getting all of it.
Shoot for around a 6.2-6.5 if you can.
Some plants are more tolerant than others, but mine, I drop my water PH to about 7.0, no matter whether adding nutes or not, and never had an issue. (knock on wood).

Thanks guys, I did flush the soil last night and even after adding 10 gallons of fresh water in the soil I was still getting high ppm. I have an occilating fan on there but it's not directly blowing on the plants, I will flush some more tomorrow and see what I get.

If you are measuring run-off...you are getting high ppms because of the solids in the water. That doesnt mean anything. Ppms are not a measurement of nutes. It is a measurement of solids in the water. Ppm measurement of run off is useless.

Some posts mentioned windburn. Fans too high? Are they getting fresh outside air?

From the pics...Ill bet you dont have any fresh air getting to them...so plants are eating themselves....

Really ,solids in the water I would rethink that.

The room is 5 x 5 x 8. And there is a 250 cfm taking the hot air out and on the bottom of the room a 170 cfm online fan blowing inside.and the ocsilating fan is blowing just above the plant at the lowest speed, so I doubt it would be from the air. Nute burn usually affect the tips of the leaves this is the entire leaves getting affected and dying.

Is that 170 fan bringing in fresh outside air?
