Flowering started

Hi my plants are really healthy coming out of vegetation their one week into flower. Do I stop nitrogen all together right away and use phosphorus and potassium? I watered with RO H20 supplemented with calmag the last two waterings. Do I need to flush? I’m vermiculturing and my worms give loft a daily liquid rich in nutrients and microorganisms can I keep on using that to water also? It’s a salt free fertilizer. Thank you


Ramp up your P and K. I always continue to feed some (reduced) about of nitrogen through week 4 in flowering to support the stretch.


Thank you
