That looks like low iron but I'd bet it's caused by a slightly too high pH causing it to be unavailable to the plant tho you probably have plenty enough in there.
Let it dry out some then water with pH 6. You want around 6.5 for most soil grows tho you shouldn't really have to pH if you have decent soil.
I'd quit the silica for now as it's very caustic and most soils have enough in them. More for hydro but OK if all is well in soil too. I use it but sparingly even in DWC.
Growing in an all organic mix for the first time in almost 20 years now and it's going good so far. Just ProMix HP for a base with sheep and steer manure, some earthworm castings and some myco for good bacteria and fungal action. Just put all that into the mix without 'cooking' and they seem happy and healthy tho not growing all that fast under a 400W CMH. Going to mix up a bigger batch and let it 'cook' for 3 or 4 weeks so it's ready for when I up-pot from the 2L pots they are in now to either 10 or 15L pots. A week after that they will go into flower.
I found a great spot to download FREE POT BOOKS. I downloaded a grow bible first and got lots more. Books look great and complete like the real ones I have here. No web site but just a page of links. Just right click on what you want and then "Save Link As" to download so they don't open first as some are 50+ megs. They got lots. Enjoy.
