Starting week 3 today, with a challenge ahead with this little bad girl! It seems to be a lack of Nitrogen, and I'm pretty afraid of burning the plant. I'm feeding the plant once each two days, with Seaweed Tonic, 150ml with the suggested dilution from the bottle. Now I have also a bottle of Canna Terra Vega, with NPKS 3-0-3-0. Is it a good idea to start feeding the plant, with also this nutrient? The soil is a mixture of 80% organic soil + 20% of coco coir. Could be a lack of nutrients from the soil? What is the best agenda to follow with nutrients? (: Cheers!! UPDATE (17/02 - Day 17): based on the suggestions made by many members, I've tried to gather the best of all and decided to make some moves in an effort to save this plant, and to avoid the same situation to the other 2 plants: #1 - Lifted the LED panel to double of the height, so the distance to the plants went from 50cm to 100cm #2 - This change with the distance from LED panel helped to low down the highest temperature achieved during the day from 27.5°C to 24°C #3 - Since day 15, the plants haven't been watered, in a move to try to dry a little bit the soil, once I was watering every day with something close to 250ml a day. Now I'll return with water in a few days, while I wait for some signals from the plants that they are needing water #4 - Pushed forward the idea to start feeding them this week, and maybe I give just a little bit of seaweed solution to root development when I come back with watering. Hope it works fine!
