Well best amd probably only way is to have an ec meter. Ppm's are converted numbers from ec thats measured and differing from manufacturer the ec is multiplied by 500,600 or 700 to get the PPM's

Accidentally poured 2mL of "Grow Big" into "Big Bloom" bottle.
I absentmindedly put 2mL of FF "grow big" directly into the bottle of"Big Bloom" (the murky one with bat guano). Is there going any type of reaction that will create products that would be unsafe for my plants? Haven't taken chemistry yet. Is it ruined?

Adding P20 and K20 to a 8-0-0 and 0-6-12 A B
I'm feeding Bionova Coco Forte A+B which is 8-0-0 and 0-6-12. I'm afraid my buds will be airy due to low P and K dosages. Do you think this will be the case? I was thinking of adding Bionova P20 and K20 to the schedule as she enters flower. Too much or should I go for it?

Diamond black vs. Diamond nectar by GHE
Hi everyone, I've read Diamond nectar is very good. But I noticed there is a very similar product from the same brand: diamond black. I was wondering what's the difference, and which one would be the best in an indoor grow in coco with high frequency fertigation. Thanks

Good Nutrient Mixture For GH Flora
My outdoors are transitioning and I got GH Flora Series (Micro, Gro, Bloom). I mixed 2.5ml of each into 1 gallon of water (4 L) and spread that across my 4 plants. I feel like this was too little? What is a good general mixture for 1 plant, or is it better to make a bigger batch?
