The best dude, Blackstrap is what you'll find most people on here using so yeah, get that one if you can
:smokebuds:
Most growers use CalMag yes but even more so when they are growing with LEDs there seems to be a bigger demand for it..
I have dropped my CalMag completely and kept my Alg A Mic at 4ml per l from week 5 and ive not realy had much Cal or Mag defs.
My advice would be use grow bloom and alg a mic.(if your not getting CalMag)
Thank you guys/girls for all the good replys!!!I use epsom salts for mag, don't have to add calcium as i use Fish-Mix.
Sounds like i got a couple of good choices! I will use CFL for the whole grow.
I will buy the blackstrap molasses cause ive seen good results with it. The calMag could wait a couple of weeks to see further on if they will need it or not
