After only 2 weeks?I use a 400 watt hps as well and they are perfectly capable of growing big fat buds.
Let me know and i will try to help you
I purchased the cool tube 'bout $85. I think it's borosillicate glass. I don't think they give any consideration to spectral integrity when they make this glass by the way, its selection is based purely on its low thermal expansion.If you give me some more info i will try to help you.
That cool tube you have.
Did you build it yourself?
If so did you use the proper type of glass to stop it from filtering out all of your essential light?
You will have serious problems getting a decent amount of veg from a hps bulb alone as they only emit red light.
Well for a 400 mh bulb that is the skinniest ak47 i have ever seen,no offence.I purchased the cool tube 'bout $85. I think it's borosillicate glass.

I vegged under a mh 400W.
Try 20% perlite and you've probably burned the fine haired root systems right off unless you flushed it through within 24 hours.It's 7% perlite. I fed it with 1500 ppm, I'm pretty sure that's why it burned, when I'm shooting for 650 ppm

Use mycorihazea fungus to repair the root functions and your plant will come back to life
No that plant was about 42" tall at the final harvest day.by the way, your plant is 6 feet tall, while mine is 10"
cool, how do you get it? just ask for it at the hydro shop?
