What kind of deficiency i am facing here?
The plant is Royal Jack auto in his 6th week from seed. I have been feeding nutrients from BioBizz based on 1/4 of their given scheme. Watering with 3L whenever the pot feels light (every 2-3 days)
I personally guess that its a combined : too intense light and a bit too weak feeding.
Looks like bleachind and calcium spots starting to appear.
In diaries photos saw signs of magnesium too.
Wise dose of calmag and raising lights should sort.
Wait for other answers, i could be wrong.
You might be a touch pale or not if these pics were taken under your grow lights. What you're seeing is very minor. Maybe slightly bump up your CalMag but don't overcorrect.
