yes i thought it was kind of low but i still managed to raise it a little and i've read that if you variate too much your ph your plant might react get some kind of burn/yellowing in middle of leaves
and today i've found a quite accurate way to measure the ph from root zone, here is the parts:
"You can assume that the pH of the water that runs out the bottom of your plant is about halfway between the pH of the water you put in and of the pH of the root zone.
So for example, if you water your plants with water that has been pH'ed to 6.0, and the water that comes out the bottom has a pH of 6.5, you can assume the pH of your root zone must be around 7.0, because the water that came out was 6.5, which is halfway between 6.0 and 7.0."

i watered #3 with 7.2 or 8.0 (with baking soda) dont remember which one lol, i get 5.7 at bottom that would be 6.85 ph if i did with 8.0 water or 6.5 with 7.2,
same for #2 im pretty sure it was 7.2 that i used to water, that would mean 6.7
theyre both in range all good, will check after next watering
this is my first time ever growing a plant in general im quite impressed how they can recover and theyre reactions to any situations
seems that you really like that strain
they started smelling not fruity but some hempy smell, cant wait till those buds appear
flushing with neutral water is a good idea ill see if it changes havent noticed because i havent added much nutes yet so my soil must be quite acidic
