SF-400 on 60 cm for seedlings ... wooow thats heavy
and in every case to strong// to close
Plants will grow much better in dimming// and give more distance
As they are in bloom, look for good hydration, water often to keep them vigor
because they transpirate the water and the nutrients remain... delute your feedings, asn likely give alow feeding solution every dayand enough water// vs, only feeing with regular dosage
The growing under Quantumboards changed drasticly, but if you adapt , they will shine
Go on 75cm and dimm to at least 50 percent
And look in the desriptions at the core coverage of the plant in flower... that shows you , how far you can go
But every Plant is different
So play around alittle and get used to you new High quality Light
