Nearing Harvest - Need Advice

Took all the girls out of the greenhouse today for a straight shot of water and molasses. This was no easy task due to their size and weight. Anyway, I ended up testing the PH going in and the PH coming out. Without any adjustment:

PH in = 7.3
PH out = 4.5

The plants are about 3 weeks from harvest, and showing some magnesium deficiency. Other than that, they are in good health and budding vigorously. I thought that I would get some PH Up and raise the PH going in to 8.3. What do you think? Tinker or just let it be?

...not sure about tinkering with Ph now...but I always included in the normal watering a pinch of epsom salt for mag. during flowering, about once a week.

I have some cal -mag if needed

I used some epsom salts. Here's a pic taken today.

Heading out the roof! I had to move a Juicy Fruit off the bench today. The fan was in a decapitation mode. Warm today

Time to remodel the greenhouse! On another matter, was debating with myself last night as to whether to cut the fertilizer on the widows. The left side of my brain won; they get one more shot of Tiger! P.S. Tried a bit of the homemade hash that I extracted via Everclear. Way surpassed my expectation!

Here are some pics taken today. Maybe a week or so to go!

wow, they're really fat now.

Maybe a couple more weeks...

Have you checked the trichomes yet?

Buzz. Checked them this morning. They are about 90% cloudy w/ a few starting to take on an amber hue. It's getting close. I want them to fully developed and swollen, but have to pay close attention to the possibility of bud rot. Have a fan going 24/7.

A week sounds about right then, depending on what you want it to smoke like. Nice greenhouse grow by the way, is it getting damp in there now?
