Leaves discolored,drying out.

Based on the number of pictures and the general look of your plants I'd guess you are only dealing with potentially 2 issues. The first is that they look like they may be getting too much nitrogen as the tips look like they have signs of that and second because the plants look healthy overall I'd say based on your comment of not knowing the strain I'd say you have a strain in the purple family like Purple kush or Alaskan Purple

Looking at that bud pic, looks like you have more than a week to go before harvest. Probably 2 full weeks.

Whatever might be happening, i don’t think you have to worry too much as SoOrbudgal said.

what is your temps and humidity?

[SoOrbudgal]

I don't think it looks bad, looks like a fade in progress but not seeing the whole plant i can't tell if there is a real problem

On the bud or the sugar leaves ?

The tricomes are about half and half cloudy/clear with maybe a couple amber ones here and there

If it’s a photo plant at 7 weeks into flower, I wouldn’t worry about it too much. You’re probably pretty close to harvest and those big fan leaves are not doing much to help with bud growth.

What do the trichomes look like?

Looks like a natural progression for a plant 7wks into flower. Once you get the ‘fall colors’ start checking tris. She should be done in a couple weeks.

First of all. What is your PH levels in the water feeding and in your soil?
What is the humidity and the temperture?
How big is the Pot? And how much water are you feeding it, when it needs water? What about nutrients?

the only problem i can see from the info you gave and the pictures, is the color change. And leaf tips bending 90 degrees..

This is my first grow.Strain unknown. She has been in flower for 7 weeks and I'm having leaf problems. Grown in ffof. Lux readings around 70,000. Any advice is appreciated.
