Doesn’t matter. You’ll have to play with the ppm no matter what. I have the advanced. I used it 1 or 2xs the. Went with bennies so I can add carbohydrates. What I don’t understand is. I used 1g/1gallon for the stock solution. I don’t have gallons. I used 2.84L jugs. Simple math get the same ratio. Ppm around 11k. Now supposed to mix 1ml/gal of res water. I tested this. 1ml/gallon. The ppm was super low. It was more like 20mls to get it to 200. I’m not sure how much 200ppm would do I think you need to be in that 300 range. I probably had it in the res for a week. I don’t think it messed with the plants but I didn’t have my nutes locked in yet so can’t really say. Personally I never used bennies or h2o2. Botinacare nutes which were super dirty. High temp water. I’ve dealt with rot and gnats. Knock on wood using southern AG for the last 2 weeks. Both flower and veg roots exploded. Temps are hotter with the lamps up. Super white.
