Hey

When you fert the plant you need to know this golden rule:
-the first nuber is for the foliage (green)
-the second is for the flowers
-the third is for the strengh and roots(correct me if im mistiaking!)

So usually when you use ferts you want you plant to flower better, so use a 10-15-10 or 5-10-5 or 5-15-5. Check for the "bloom" ferts its always good (the peters have a good reputation).

Remember that too mush is not good and not enought isnt good either!

If you grow under and hps, you should water the sol each day (the heat of th lamps dehydrates the soil). What kind of dirt do you use? does it countains vermiculite?pearlite?sphagnum moss?

The best time to transplant is anytime! if you switch from 8 to 12 it should be enought for the plant. If you hear about root strangeling or anything similar just dont belive it: if the plant get enought food and light she will never die because of the roots. I had a friend that grew 2 plants in a 3x4 pot (im not lying to you this is for real) and they grew 5feet 6" tall. So im alot ceptic for that rumor (i call it a rmor because i have never seen such things like that)

I hope this will help !!! see ya have fun and take your time!


p.S: those are pics from my power plant enjoy!
