NYC Sour D #1: Slightly slower growth compared to the other two strains. But the larger of this strain. Slight spots on the first leaves. Possibly lime residue from spraying. Or does the community here have a different opinion? Please let me know. #2: The lowest growth of all 6 plants. Also possibly lime residue on the leaves. Royal Cookies Auto #1: Largest plant in the tent. Trunk could be a bit thicker. But I am satisfied so far. Leaves are praying upwards. #2: Second largest plant. Slight waves in the 2nd pair of leaves. Must be observed. Royal Haze Auto #1: Good growth. Slight purple coloration on the stem. Small discoloration on the leaf. Problem? #2: Everything looks good. Is the smaller of this strain. Light settings 45% dimmer at 45 cm distance Between 520 and 770 ppfd. Should I turn the dimmer down a little bit? What do you think?
