Hey guys so like I said I ordered some ph up and down and a ph pen, I remember reading way way back that you have to be careful using them with like getting it on your skin or on your plants, is that right.? And I know to check ph after adding regular nutrients that's why i can correct it properly. Is there anything else I need to know with using Ph up and down?

Curious if anyone here uses defoliation on their autos. Any info and links would be much appreciated.
Hey JimmysAuto, good to see you here!
I battle mold so I defold, fall greenhouse high RH, defol then let's the air in, and I can keep my eye on everything. If I wasn't battling mold I probably would defol very little. Worn out fans no longer photosynthesizing, and places where leaves are way bunched up. There are lots of opinions about defoliation on AFN!

don't know about your nutes. In ph pin discussions I've noted that keeping probs clean is key to function

Ph down is very strong stuff literally drops per gallon, ph up not so strong. I've never needed ph up, if I do need to raise ph a little I just use rhizotonic to do it.
