Is this a deficiency?
lotuslordstarted grow question 2 years ago
Hello there,
Today I saw that some of my plants have some curled and sad looking leaves (see pic). The soil is pre-fertilized and I currently use normal tap water (p.H. adjusted) for watering. My plants get 18hrs of light a day (approx. 300-400PPFD)
Thanks for you help guys :)

bad ph
bad watering regime, which played with pots ph
too much nutrition, nitrogen
too rich soil
