basically, i just want some confirmation from a few other people that it looks like ph burn.










long story short, didnt recalibrate my ph pen for 6 weeks, kinda embarrassing.
after i calibrated it i realized just how off it was.

was wanting to know tho what everyone keeps their rockwool at. i've been tryin to keep mine at 5.5-5.8, but the res water is almost always at 5.8

what should i be aiming for???

any help appreciated.

I was just curious what you are feeding these? How much and how often? You said your ph has been off. Too high or low?

feeding GH floranutes 1/2 str, every feeding so far. ph was way too high, basically cause my pen was off, when i calibrated it the 5.8 jumped to 7.1.

5.5-5.8 is the correct ph range i'm looking to get for rockwool tho correct?

ph issues and nturient burn, there is no such thing as ph burn. Its nutrient burn and im sure ph has caused worse cnoditions from over feeding


flush your plants and replace the water with proper ph and nutrients

what ppms is your system right now?

the GH feeding schedule someone sent me said for veg, grow-12.5,micro-7.5, bloom-2.5, and i've only been feeding them at half of that.

i'm unsure of my ppm because i have yet to buy a ppm pen =(

i would imagine this has just been caused by the ph being off for such a period of time.

thanks for all the input guys, i'll see if i cant get it straightened out.
take care,
Dirty
