Tomatoes Nutrients 2 plants compare on Kratky Method Part 1

So I started 2 plants of tomatoes on the same date with different solutions these plants are 2 weeks old and one of them is on a solution mix of Masterblend (left) and the other is on Dyna-Grow 7-9-5 (right) on Kratky Method both using same light sources and area. The masterblend look like is taking off and look more strong from both the only different on my test was the PH when I mix the ingredients am not sure is this is the case but who knows. Any way I will keep updating this and posting in 7 days to see if there any differences .
