Wedding Gelato & Royal Gorilla First Gro

Incredible week learned so much! I can swear the WG has super genetics - she sprouted so fast and her roots rushed out of the rock wool in no time, she tolerated my mistakes and continues to thrive. RG sprouted two days later so she didn’t witness the same conditions her sister has but she is very short! Leaves look good, roots hit the water but I guess she should grow better now. Wedding Gelato sprouted quickly and strongly but due to my lack of experience and eagerness considering this my first grow I made some fundamental mistakes that I advise beginners to avoid: 1) Do not rush into nutrients - I gave her too much in her first few days which caused a tip burn. The water was around 900 PPM with an EC of 1.2 and the RH in the room was around 30%! Relatively unfavorable conditions for a seedling so I had to remove half of the water in the tank and refill with PH balanced RO water that took down the readings to half and immediately things got better! 2) Do NOT expose the water in the DWC reservoir to light LOL I was basically encouraging an orgy for bacteria and algae in the tank, WG started drooping so I checked her roots and saw those brown spots and freaked out - So I added 4 vials of 60 ml 6% hydrogen peroxide and I swear it was like magic - she is up and her roots are looking fine I’m loving this and enjoying it beyond words. Hope they’ll survive
