i am not sure if this is genetic or nutrient/ph problem.

I noticed it then went and got Ca and Mg as well as some FF big bloom. Fed it 3 days ago.

The purple is still there but everything seems fine except for my humidity and air ventilation which i fixed by puting concealed holes in the wall.

I have a light fan on them as well to keep things cooler (80 degrees, 20% humidity).

I spray them still which i should probobly stop soon but at 80% it evaps.

Oh ya, 1st pic you can see it in the center of the pic..on the leaf and tips, its generally around in the next 3 pics as well as a pic of some burn.

Leaves on the bottom are yellowing but not dying at all which is expected and this is day 35 of flowering

It's difficult to help you with those pictures. The types of light you're using alter the true coloration of the leaves and your pictures are blurry to boot. Turn off your LEDs for a minute and give us some fluorescent lighting so it's easier to see, or snip off a leaf and hold it under your kitchen light.

That said, it may be an overnute problem. It looks like your leaves are doing the claw shape (edges folding down and in) but again, it's hard to tell with those pictures. If the new growth is curling down and in then flush your system and run quarter nutes for a week.

How cold is it where your at? Temperature below 60 degrees overnight can cause the plant to turn purple.

It is genetics... My white demon turns purple when its getting real close to harvest in the last couple weeks. It normally coincides with the change of the trichs from cloudy to amber in my strain so its a good gauge. Cold temps accelerate this.

ya well this strain is p99, cinderella99 with PH but it was crossed to pull away from the PH cause its real finicky.

You all sure its genetics? you can see the purple i am talking about? its not rampant like i usually see it

i would upgrade to hi-output...not for yield purposes. I honestly see a difference between HID and LED. That difference is no electricity, doesnt make my place smell like dank all the time, no loud fans humming during the night, no large ventilation tubing required. Honestly id rather grow a few extra to make up for any loss of yield..

LEDs are pretty sick MSG me for more info. Theres so many haters here.
