When should I switch to flowering nutrients

I think what I’m seeing is the first stages of flowering. I noticed these white hairs on all plants at the beginning of the week. Should I switch to flowering nutrients next water change or stay in the grow nutrients for another week?
Here is a list of my setup if needed
4x4x6.5’ tent

RDWC system 4 five gallon grow bkts

5 gallon reservoir

1/10 hp water chiller

950 gph air pump

2”x4” air stone in each bucket

12” oscillating fan

1200w king plus led 24” from canopy

6” 400 cfm exhaust fan and filter

Ph level 5.9

PPM 723

Water temp 68.5F

Air temp 75F

I usually split the difference between the manufacturers recommended nutrient schedule, and what I see the plants doing.
If it were me, I would still keep on the nitrogen for a bit, but still adding flowering nutrients. At this point you’re supporting the stretch, and flowering. @Fluffy

I’ve been doing about 1/2 strength on the maxigrow should I stick with that an go about 1/4 strength on the flower nutrients or should I go more?

This should help. @Fluffy

@covertgrower thanks. I have been using that schedule but have been told to start out using 1/2 strength and work my way up from there. I was using the bergmans but found out they said that was more for soil because I was running out of what was sent in the first week. They recommended me to switch to the maxi series starting out at 1/2 strength. I’m on my first week of using it and finishing up third week of veg

@Fluffy you’re on track with 1/2 strength. You can over do nutrients quickly and it’s sometimes more difficult to recover. Just watch for deficiencies and you’ll do great.

@Covertgrower

That was perfect awesome info that you gave. 1
