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.

First leaves curved ?
On Purple Lemonade and Six Shooter the leaves develop a bit slower, but that's okay I guess. But the first leaves are all curved, is that a problem?

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?

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)
Maturity in day 49 flower from 60-65 (according to breeder) I'm not sure about the degree of ripeness. I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ? What should I do Thank you
