After following Weezards posts on LEDs elsewhere I'm wondering if I have a bit too much light in my tent so I've ordered a lux meter and will take some measurements when it arrives.

Worth doing, I learned a lot with the lux meter.

'til it comes though, a practical indicator of too much light ,( over 91k lux), is a drastic slowing of photosynthesis.
Good indicator of that, is transpiration.

If you have a spare scale, set the plant on it and leave it there.
If the weight stays constant for more than a day, she's not moving water, growth has stopped, raise the light an inch or so and see if it resumes.

Watered the front plant with 1/2 ususal amount at 1/4 nute strength this morning. rear plant has about 1 more day until it needs water/nutes.

That said, those girls look great! :greenthumb:

Seems they are still drinking and they look ready to me. unless you are shooting for couchlock.

If so, be aware that waiting for amber trichs under LEDs can be misleading.
Without UVb cooking them you will only get amber from senescence.
I let my first crop go too long.
This last crop chop was "mostly-cloudy".
Talk about peak production!
I've been silly-high for two weeks.:stoned:

Have you had an "oops" test yet?

"I swear, it was an accident, this branch just fell right off"
Perhaps, I'll dry an try.
