I notice the GH series available in UK is slightly different from the USA formula

UK/EU FloaGro 3-1-6, USA Floragro 2-1-6
Will this make much difference to the feeding schedule?

I am growing RDWC will be feeding no more than 700 ppm Hanna (1.4 ec) max maybe a little less in mid bloom. Is this enough?? My background tap water is 50-100 ppm very soft.

Another few questions if I may.

I plan to use no boosters or PK supplements just some Raw Silica, Raw Humic acids, Cal/mag and GH series. Would this be adequate or should I add boosters etc ??

Do i stick to the 3 part ratio advised by GH on their website or is there a more Cannabis specific ratio??
