Ive begun calculating N, P, & K amounts, along with magnesium, calcium, and sulfur. I try to hit target amounts of these elements in my mixtures. I refer to a chart that has different minimum ppm's of these elements for veg and flower stages.
Ive noticed, using GH nutes, that...
- it is hard to reach target levels of nutrients without getting tip burn
- sulfur levels are way lower then the minimum value on the chart which asks for 60 ppm sulfur, i hit 12 -15
- i need higher levels of magnesium and calcium to keep plants happy
- plants seem to need more phosphorous and less potassium as flowering progresses
Please share your option, experience, or rants. I'm curious if anyone else calculates nutes like this and has noticed trends, has advice, resources, etc.
