13 hour dark ?

depends on the strain, but usually found that it takes about an extra week to finish up. I dont know about lowering to 59, that to me sounds a little low. I usually have mine set at about 65-66 in in the last week and have the water level lower. . Drop the temperatures to much and it could cause some slow growth. I am sure some of seasoned veterans will chime in and be able to answer it better. Before chop down, I run a 48 hour dark period.

thx for the response

I dropped my temps into the high 50's but just the last week and drop the water level to around 2/3 or even 1/2 that final week. I've also cut my lighting back. Actually around week 7 I throw mostly metal halide 10k bulbs in the room instead of the 4k bloom bulbs not sure which one of those things stack the crystals like I see but that shit works. Trichromes get so big the bud glistens and looks wet. Last test was at 27% THCA.

This is always helpful
