What is this?

The leaves at the top of the plants have been fading in color and riddled with brownish spots. Maybe this pic can help you diagnose. Appreciate any advice you could give.

HMMM, looking at the pic (which is not so great btw) as well as reading your description. I am gonna go with too much N. Here is a pic that may help.

Any recommendation on how to treat?

Flush her out and wait a couple of waterings until you resume feeding and then start again at 1/2 strength. But before you do anything...get other opinions. Your question is kind of vague. Need more info really...soil, nutes, ph, humidity, temperature etc. Good Luck.

N or P,,,i think your ph is out too,leaf swirling a bit......like budz says shit piccie,,but i dont think its fatal...flush for a start.........

cal mag !!!!!!!!!

Wow, you know maybe we should all stop our nute regimens, plant in soiless or hydro and water or res with gallons of cal/mag. It seems so many think it is the miracle cure all for every issue a plant can possibly have. I have seen people post about thrips and someone replies "CAL/MAG"

Please take no offense to this str8sativa. It was not your post that prompted this reply. I have spent A LOT of time here recently and I see this type of reply 5 times a day on average.
