Hello all! Little update and a question. The plants seem to be all doing well and REALLY need to go into flower but I was told that i need to give them a feeding of FF grow big and open sesame a week before i put them into flower. Is this 100 pct true? The blues got nutes last feeding and the bag seed plants in the front row were flushed with water to correct an issue that has since cleared up. Can i start flowering and feed them in about 4 days with the recommended nutes?
thanx

p.s. Almost forgot to mention that the blues are 4 weeks and the bags are 5 weeks.
thanx again.
