Ph dropping in dwc veg stage

So I've been growing these clones out for almost a month. I've had a few hiccups and have been finding great info here to help me correct and get them back on track. The last couple of days I've had ph drops in a 24 hour period of from 5.6 to 4.77 being the largest. I over nuted in the beginning but currently have been a steady .6 EC for the past week

Plants are growing well and root growth is doing good. Should I be worried about these new ph drops or just add ph up. Or should I dilute the nutes even further. I'm using recipe for success at quarter strength of there recommended recipe.
Thanks

tell me how many mls of each of the techna flora products your adding per gallon

whats your water source?

how long ago did you lower your EC and how high did you have it when it was too high?

Satori. You helped me earlier with some nute recommendations. Thanks
Tap water left out for one day
Mixing the following into one gallon of water and then diluting further.
Boost 15 ml
Grow 7.5 ml
Thrive b1 red 2.5ml
Magical 2.5 ml
Sugar daddy 12.5 ml
That one gallon of nutrient gets mixed with between 5 and 6 gallons of water to then get divided for my 6 buckets. ( hope you understand that). So with my truncheon I'm at .6 and have been there for over two weeks. Last nute change was 6 days ago. I've had good upward drift on the ph for the first three weeks. After this change I drifted up the first day, held steady for two and now have dropped ph the last two days. I estimate they have taken up about a half a gallon each. I wish I could be more exact with the measurements but I've been relying on the truncheon and ph meter to be accurate. I have checked and rechecked calibration on ph meter as well

Thanks

feed them per gallon

10mls boost
5mls grow
1gram per gallon of Epsom salt
thrive b1

dump the sugar and you don't need the magical in veg
use the Epsom salt you need it for sure

first flush them with half strength

5ML boost
2,5mls grow

and so on

then dump the nutes and refill the reservoir per above directions

Thanks again how much of the thrive b1 per gallon

How long on the flush ?

that's mostly kelp isn't it?
id say as directed

does it list the % amounts

I don't have the info for it

you can post a pic of the % amounts and I can see if it changes anything but if its just kelp it wont

maybe 15minutes
