Dynagrow Foliage Pro Questions

I'd suggest no using FP with early veg/seedlings. I think grow is a better choice at that stage. Start low and don't trust their feed charts either. Or at least be more careful with FP. I bought some FP 6 months ago and I've only used DG. Long story short when I bought it I had mothers and cuttings. I had no bad results with those plants. Since then I got spider mites. Eventually I culled most of library. I wanted to toss some strains others I wanted to search for a better pheno.

The first batch of seedlings were going great. I've never had a problem with seedlings or plants in veg ever. I started a second strain a month after the first. So when I noticed the old leaves of the first batch were starting to yellow and get brown spots. My first reaction was I was low on N because this issue I've had several times in early flower. Which is why I bought FP in the first place. Since it takes less FP to add N during flower I can use more bloom than if I were to use grow. Only this time it wasn't giving me the desired result. At this point the problem was starting to show up on my second batch. So I switched back to grow. I caught it in time on the second batch. Unfortunately the first batch I culled the females with the males and only kept the cuts of each female. I didn't want to start a flowering cycle with leaves yellowing and falling off. So for the time being I'm only using FP on well established plants. At this point I think young plants benefit from the added phosphorus and FP just can't provide that.

Are you using tap water?

I promise that you didn't burn plants at that rate. Something else is going on.

tap water and promix. One in hp an 2 in potting. All Ph'd correctly for their mediums using a digi and a reg drop test kit.
Those seedsman nl's were a real bitch. All of them suffered the same claw and burnt tips.

Could have been the strain because my SD didn't have a problem with the same levels. The nl seeds were small and light green, nothing like the ones I made from those plants. Mine are normal brown with stripes.

The thing about foliage pro and seedlings is that even at a strong dose of 1 tsp/gal, you're not watering seedlings with more than an ounce or two of water. Think about how much actual plant food you're giving a seedling at a watering rate of 2 ounces/watering. That equals just over 1 single drop of plant food at that watering rate. I just don't see how that small amount of food is burning your plants. I suspect your water is screwing things up.
 
No more than 3ml/gal. But that's after its well established. Before that I dilute it. I'll add RO water until I get to my desired PPM. The first dose would be at 30-40 ppm. Then slowly work up. It was very odd I'm still not sure if I am right in my assumption of phosphorus deficiency. I also added 20 ppm of cal/mag. (Before diluted) because it looked like several deficiencies. For whatever reason I can't look at the leaf deficiency picture chart that is floating around the net and decide what the problem was. They all look fairly similar to me. So I figured added a little cal/mag couldn't hurt.
