Amnesia lemon feminised

Still going strong, plant started showing some burns at the tip of the leaves. I get that everytime, doesn't get any worst. Let me know if you know what's causing it. Increased dosage of nutes may have contributed. Microscopic image of the trichomes shows that they are mostly clear. Just a few in the big leaves are turning closely. Looks like plant is on track, probably one or two more weeks with nuts and then 2 full weeks of flush. I'm almost there, just a matter of time until i can enjoy those sticky buddy.
