hey,
plant is around 2 weeks old and leaves are starting to curl up from the stem. also there is a bit of purple color on the stems, so maybe phosphorous deficiency?
Today, I've fed her half of recommended nutrient dosage 0.65 EC, pH below 5.8. Watering before that was done with pHed water about 2 days ago and before that with 1/8 of nutrients. She is in 12 liter textile pot and i've used with 600ml of water.
I've also considered heat stress but for last 2 days I've been thoroughly controlling the temp.
So my best guess is salt build up / or too acidic pH? Should I flush the plant with just pHed water until runoff ?
Also should I water 2 week old plant till runoff or just 600ml is fine? I can't check for ppm of runoff if I don't have any :/
Light is CFL 200w around 15cm from the plant, temps are between 20-28 day 15-18 during night. RH is 50%
