hi there Habosabin, that's micronutrient deficiency, you're adding silica which is basically optional but you're forgetting calmag which is absolutely necessary in soiless grows. Just add calmag asap . Hope this helps ! 🚀

It looks like the beginning stages of a magnesium or a nitrogen deficiency, when the light is nice and close the plant will eat up the calcium and magnesium very quickly. If the PH of the substrate is too high or low you may run into other deficiencies or abundance’s causing a burn. I would start with confirming the PH of the substrate and the water first. Whatever the culprit it still seems very mild; and you have a gorgeous plant! Good luck and happy growing

Keep an eye on your plants but I think you'll be ok. You may have to adjust nutrients added so not to burn the plant. Play it by ear; If you spend a lot of time with her then that shouldn't be a problem. I know ground source water is always UVC blasted (or at least it should be) so you shouldn't have any harmful bacteria. You can get home devices that UVC your water as it comes in. Seen them with other more personal ground source water. It will lose calcium as it moves through pipes and collecting in certain areas. They are testing at the source and will be higher. I hope this helps, good luck and happy growing
