Excellent plant. Did you add biobloom only once? Or did you feed additionally during flowering?

Holy, that's some serious Purple Punch Auto!

@Mnogumba, Nothing to thank buddy :-) Yes, I think so, too . In the past, with the sodium vapor lamp, I didn't have a cal / mag deficiency until I switched to LED. With the mixture as described above, I drive perfectly 👍

@MadeInGermany, Thanks for the answer. I think this is the smartest way to avoid magnesium / calcium deficiencies.
