AsNoriuanswered grow question 2 years ago Humidity and temperature for veg too low.
I had best results at 70-80 rh and 26-28 celcius at day time
Search for vpd chart
Ph a bit too hight, drop to 6.3-6.4
The rest as i said, i had that type of leaf as last red flag, if i wont stop feeding , all issues would start.
Light cal mag always good, add it to your feed days , but around 0.25-0.5 ml/L
Happy Growing !!!
