hi dude ! i can't be sure but for me it's look like a chain reaction with your silicon nutes
from the manufacturer " Aggressives are types of substance which can cause damage to skin and clothing and can cause burns. This group of products includes, but is not limited to: pH Up (potassium hydroxide), pH Down (nitric acid, phosphoric acid, citric acid), Liquid oxygen (hydrogen peroxide) and products containing liquid forms of silica/silicon. Always add straight to your reservoir water and mix well straight away. Do not mix aggressive substances with any other product while in their concentrated form. When using, always wear suitable protection (gloves, goggles etc.) and keep out of the reach of children at all times."
hope this help ! good luck for ur grow dude 👊
