Got my soil ph down ... what's next

had a soil problem it's ph was at 8 I amended it with urea now it's in the 6.0-7.0 range .... now I have liquid nutrients FF Grow Big, VitaminB1 ,and fish fertilizer (liquid) my question is will my nutrients/waters PH disrupt my soils PH ? I know the nutrients are optional but I am tryna yield a lot

Just don't overuse. Start at quarter strength

Never had a problem myself as stated start slow with the nutes.I like to put some water on the plants before i add the nutes.

Alright well I got like 37 clones my soil is in range I wanna add vitamin b1 and BioRoot 0-1-1 to a bucket of water how much should I add 1 cap full of each ... I'm gonna dunk the plants in thier containers into the water ... what should the ph of the water be ... its 7.0 no with no nutes I know the ph drops when I add b1 and BioRoot so what's should my solutions ph be?

No need for PH outdoors imo
