4)besides the gh flora series, i was looking to get liquid karma, megagro, and also some superthrive... sound complete enough or should i be looking at any other products? (ill think about bloom bud and big bud when the time comes, for now, they are babies)
5)can any of the previously mentioned nutrients be used for soil grows with any success?
1...do the math...example:1 qt/liter ml per gallon (5) times res capacity (18);
So, 5x18...then divide that into 1qt/liter...So, 1000ml divided by 90ml(5x18)=?

That is how many res changes you will get from that size bottle

2...7-10 days. Watch your plants...add ph'd ROwater in between res changes. this allows for the leaching of some salts before next dose of tea.

3...Don't start putting alot of "CRAP in your res...It will only tangle in the 'root system'...

4...If you get Liquid Karma, you don't need Superthrive, but I have both and use Superthrive as a tried and tested stress reducer. If you have three part you can double your bloom nutes to enhance flower...I would add Calmag+ if you use ROwater, because RO removes the calmag in your water...And get some Hygrozyme for the enzyme protection of your res...If you cannot afford Hygrozyme...then buy Advanced Nutrients Sensi-Zyme...keep in mind that You use about 3parts sensi to gallon///Hygrozyme you add 2 parts to gallon; In comparison to amount used per/and determining cost per dose...I switched to Hygrozyme(organic; also, if that matters)...you have to read up on both and make the call.

5...yes

hope this helps...I haven't stopped in too much, because i have seen that you have many advisors...peace.lw
