Dyna Gro is highly concentrated so less is more. If you are growing in coco I'll post a recommended feed chart below. This feed chart was created by Costa Mesa Steve, so I want to give credit where it's deserved. His Feed Chart was developed using Growmore Nutrients, however it works perfectly for Dyna Gro.
Just one other thing to note - the highest my PPM's ever go are about 800, and even then there are only a few strains that can routinely feed that heavy in my experience. You'll want to gradually work your way up.
By the way - when you add 5ML calmag to your RO water it's going to increase the PPM's significantly so don't be scared of that. Follow what I have down below and I can damn near guarantee you'll be really successful with DG. Once you get comfortable then you can start tweaking things.
**I'm assuming you are using R/O water**
If you are using tap water then cut the Calmag down to 2.5ML or even 0 depending on your tap water PPM's.
**If using coco then feed this every watering**
**If using soil then feed this recipe 1x per week, with normal watering in between of just 5ML calmag and RO water + 2.5ML of Recharge**
