Help Please!: Not Sure What is Wrong...

Has anyone ever come across this problem? The leaves are turning yellow, near the bottom with some brownish colors and I can't figure it out. Here are some pictures:

Please note this is occurring from the bottom to up to three quarters of the way up on almost all of my plants.

The temperature ranges from about 65 - 72 degrees throughout the day with a relative humidity of 38-48%.

Even without the form filled out, the plant is obviously nute burned and is suffering lockout. Flush. Form is in my signature, we can be more accurate with that filled out. Thanks.... PH is too low also.

Yep, sativa's are sensitive to N, and the incoming PH is too low. Is it possibly time to repot? Lockout with burn.

Flush and repot if you can and lay off the nutes. Use molasses 1 tsp/gal

Thanks for the advice! It is much appreciated.
