answered grow question 4y ago
Hello. In the back of my Advanced Nutrient catalogue it has charts that are up to 2000 ppm. I usually do 800 to 1000 ppm in veg and 1200 to 1400 ppm in flowering. At 1600 I usually get some leaf tip burning and huge buds.. Chuck.

Efficient Nutrient Mixing?
Any suggestions for efficient nutrient measurement/mixing routines? I’m currently making a stinking mess every time I pour nutrients into a cup, pull up with graduated syringe and transfer to my watering container for mixing and pH. There has to be a better way…

DWC PPM First feed
I used rainwater with ppm of 15-18 and mixed 8 gallons with 18 ml of GHE Bloom, Gro and Micro with 4 ml of CalMag. Both buckets have new PPM of 350-390. Is that too aggressive for day 9? Or can I push more? New to DWC and growing and hoping for some applied knowledge. Thanks

I stopped giving my plants Plagron Silic Rock from mid last week (week 13, week 5 flower). Can anybody tell me if I did right to cut it in flower or does anybody has experience using this nute until the end of their grow? I think this nute is just for veg and early flower.

Plagron or BioBizz?
Which nutrient pack do you prefer to use on your autos? Consider that I will use a poorly-fertilized soil like LightMix. Thanks for answering 😊🙏🏻

Should I switch to well water?
I use tap water. For our normal flower/vegetable garden we use well water. I measured the EC/PPM of both. Tap: 0.5 mS/cm (=320 ppm), we live in an area with soft tapwater according to Water Agency (11°F-13°F max) Well: 0.32 (=205 ppm) -> how do I interpret this for well water?

I need a little help with Advanced Nutrients. Without the help of ppm.
Hello, a friend confused me with the use of Advanced Nutrients, this is the easiest way for me to conclude, question. We have A, B, C nutrients, each of them goes 1ml per liter, on 1l we put all 3 components A, B, C each one ml per liter, or only one milliliter goes to each liter
