honestly no. Only testing water and runoff. cheap vivosun meters. already found out i need to invest in better testers as my ppm meter was off by almost 400. Im thinking that feed cause it was a heavier one was probably the cause of this maybe? Im not sure :/
Good tools are the first thing you need to grow.. it almost makes it foolproof outside of bad genetics or a poor environment.

promix is soiless, similar to coco without the calmag theft. but peat gets acidic over time and you need to lime your peat. promix should come prebuffed

I also doubt it's lockout because there are no visible markings on the fan leaves, they are solid green , usually the fans are the first indicator of ph swings

I think humidity may be at play here and honestly i would have never thought that was it, you guys have been incredibly helpful. oklahoma is a dry winter, so its staying around 30-40% max RH, i need to invest in a humidifier tomorrow.. My runoffs on my soil is pretty low, it was at 5.7 ph and around 700ppm (like mentioned previously i accidently over fed them)

30-40 is good for deep flower when your trying to prevent rot

in veg think of a rainforest

stay vigilant of Powdery Mildew , don't let the night RH spike , keep RH relative close in day Nd night

Ahh, a fellow Okie!.. yes, it’s very dry lately. I run a Portacool evap cooler in my grow room during veg this time of year. Try to get it up to 60+, mist down the area as much as possible.

Thank you again man. I just moved here and every other grow ive worked or done at my own house never had the need to raise the humidity, it was always to lower it as i always lived in damp areas. Not used to the super dry winters here. So low humidity can cause pretty much those symptoms in my pics? The plants reaching for the lights is something i had never seen before, and i had thought it was either a pest of some sort, or something with my feedings. I should be paying yall for this help.. lol. The stunted growth just seemed so weird to me too, but like you said i wasnt sure if it was a burn or lockout cause it would have showed on the leaves first i feel before it would stunt the growth like that

google "VPD chart" and read up on that subject if you feel inclined the relationship to temp and humidity control alot in the plant
