Make sure when using any sort of Silicate product that it is the very first thing that you mix into your solution. Also, it needs to be mixed for a few minutes as well. If you add this at any point after you have already mixed anything else, it will easily bind it up and precipitate out. Advanced Nurtients should have mixing directions for their products. It looks like you have some issues with bound up nutrients and should swap it with a fresh batch immediately. Hope this helps.

Potassium silicate was added.. depends on the ppms.. but could have locked soemthing out if too high. potassium silicate is a base, so it could have shifted your pH, too. A couple things you have to check, then take the most likely path. Algea won't cause that, no worries. don't think of fertilization of soilless/hydro as add a bit of this here and a bit of this there and whimsically add and take away things. it can use 10-20ppm of silica, if i recall? That reference info you search and apply, then observe and adjust. I wouldn't trust AN's instructions. they care more bout selling the next bottle than anything important. now, how much K is that adding? if it adds "50" then you have to deduct 50 from what the other products add, give or take, to maintain roughly the same levels and expect the same growth you saw before. JFC... top 50 google returns are all bro science with vague instructions and nothing solid to go on, lol... but it's out there. i'm not putting any more effort into searching for it. also, potassium silicate is always potassium silicate, so if you find a generic cheaper, no reason to pay for a cartoon graphic. Always add anything with Si 2nd to last... since ppm isn't as high, i'd mix in Si before something with Ca. Ca-rich products should be last. (si and ca, for that matter) 120-130N 40-60 P 180-200 K 100+ Ca 75ish Mg 100-110 S Your tap water will matter, too. Might help with some of those. Ca and Mg will probably be the most impacted. Good ballpark to start... it's a good ratio but overall concentration may need to be adjusted relative to local variables.. primarily VPD differences between gardens. This is on light side because i tend to have slgihtly higher than normal VPD. In flower i'm around 1.2EC overall concentration (calculated from nute labels and excluding what tap water adds) becaue the lights crank up, temps rise but RH doesn't scale with it (beyond the 'relative' part, of course). knowing how you feed through ppm or weighted average of your percents off labels will keep you on a good path and make adjusting, learning from things you encounter that much easier. Soon you have a formula for early on, formuala for vege and one for flower... all not significantly different but may need minor tweaks... maybe 110 ppm N in flower... nothing drastic ever should be occurring.. no need for it in soilless/hydro.

Looks like a PH drift issue to me and maybe some burning. Rhino Skin is a potassium silicate and they are very alkaline aorund PH 11. In other gudies I've read regarding Silicon they normally add it first and let it sit a bit before doing anything else. AN says to do it a bit different. * Advanced Nutrients Rhino Skin should be used from the beginning of flowering through to 1 week before harvest. Simply make up your feed/nutrient solution as usual to the required strength and add Rhino Skin at a rate of 2ml/Litre and mix well. * If your not monitoring your EC you may want to do that and retest PH once its all been mixed up to confirm its within the realms you want when using products that alter the PH greatly.
