I am in 15 gallon containers filled with rockwool grow cubes. If you've ever watched any of the greenhouse seed co guys grow videos its based on their method. So its a soiless medium I'd say more similar to your first grow except i fabricated some pvc to do the watering for me. You're absolutly right about taking my measurments on my own and then I know the PPM is correct. What i'll do is Dilute this batch with PH adjusted water and after a few days when i need to mix more I'll figure exactly what I need for 1200ppm. They're week 4 flower so its still early. The Greenhouse guys said it can take 1.9EC from weeks 2 through 6 then they start backing it down. 1.9EC by Advanced Nutes is equal to 1350. Of course i know all strains are different. This is their guide to White Rhino which is what I'm working with.
