I am in the US a medical grower here I am not so familiar with the nutrients you used,, I was able to find them available online,, I am not sure if it is appropriate to ask but do you have any thoughts on using advance nutes. and start with the formulex and use the rhizotonic and use the master regimine starting the 2nd week, manybe with the iguana j. as a main nute. Everyone loves soil here without exception, and I did a hydro grow in '82 but am not familiar at all with the newer nutes etc. I am doing my 1st grow indoor in about 14 years , starting with 4 TD. under 2 600 watt hi par HID.s. I was going to follow your regimen exactly as possible but looking at the p h perfect stuff and how my friends talk over it I may have to go with that,, Thanks so much for your post and I found it on you tube,, congratulations and hope to continue to hear and see more from you,, I am counting hard on this grow and will post here or maybe that should be another thread,, Love from US
