Hi Mate,
I don't wanna bother you, but why didn't you create an actual diary so the community could have a look at pictures, or your feeding Regime, at what pH you are watering etc.,etc. If you don't give propper Information, don't expect a precise expertise..
First of all I would have a look at the feeding schedule of your fertilizer brand. I'm sure they provide something like this. Follow this Regime, you'll get a feeling for that the more grows you do..
Good luck mate!
