Two questions...

Ok, ...First of all there`s a 5 week old plant that has been on 12/12 lighting for the past 7 days. In other words, the 12/12 was started at the end of the 4th week. She has really started to show her self. She is 5 weeks and a day old now. So from this point, should I be thinking that it will 8 more weeks before she`s ready to harvest or..??? What, in your opinion, is the most important thing to do, not do, watch, etc.etc. during these last phases??

5 weeks old
3- 150/27,000 CFL`s
2- 65 watt CFL`s
1- 40 watt CFL
1- 65 watt Blue Grow Light
The plant is surrounded by mirrors on 3 sides so the lighting is covered in several aspects.

The grow medium is 50% potting mix, 50% Peat Moss.
The nutes and minerals are vast but to name a few, Potassium, Phosphorus, sulfur, aluminum sulfate, Bone Meal, Blood Meal, Nitrogen, etc. The main feed is a 10/10/10 mixture at this point but with the addition of the Bone and Blood Meal, I`m sure the numbers are much different. Maybe something like 12/20/14 or something like that...just a pure and simple guesstimate.

Anyway, feel free too share your thoughts. Constructive criticism welcomed.

sounds like you got a good plan have fun!!

I wouldn't change anything for a couple weeks.
It looks happy and healthy, tho a little heavy on the N, but she will want N in the upcoming stretch.
It sounds like you are making your own nutes, NO?
After a couple, maybe 3 weeks when the vertical growth slows a bit, I would dial back the N just a little, and look for a little more P and K, but nothing drastic.
Is that about a 2 1/2 gallon pot?
If so, you'll probably want to go to a five gal. in a couple weeks.

It`s a 3 gallon pot. She grew wide from the beginning. The N issue was addressed a few days ago. The pot was flushed and reloaded. Thanks to "the claw"...LOL! Thanks for the response Bak.

Your mirrors are absolutely useless they don't reflect properly, you're better off surrounding your plants with flat white poster boards, you could also use mylar but flat white boards are best, nice looking grow tho.

Didn`t know that about mirrors. Don`t understand it either but I will try to educate myself on the subject. Thanks
