S02: Critical Jack Automatic by Dinafem

What a week full of problems! I have too little knowledge to tell what went wrong but almost everything went south in both water reservoirs from water and tent temperature at night, too low humidity, PH issues, nutrient burns, brownish floating things in the water to a very weak stem that cannot hold the plant up right and needs support. I've exchanged both water reservoirs, cleaned them with only water and a sponge and added 40-50L into each of fresh water and left the plants on a water only diet for a few days. They seem to get back on track very slowly but I believe they are doing better now. Critical Jack seems to look sick like an old person at the end of its journey. Don't know if I should just kill it. Even the cam couldn't focus on this shit...
