PPM too high - how does it looks like?

How does the leaves looks like when the ppm is too high?
I used 700ppm at early stage and I am afraid I burnt it

the tips of your leaves will be brown/burnt and crispy. Sounds like its time to flush the soil

thank you :slight_smile:
do you have a photo?
also, does all leaves will look like this? or only upper/lower leaves?
and, I use hydro (not soil)
thank you

Need a pic… :wink:

:v::sunglasses:

you’re right. I already cut all problematic leaves. will upload next time.
thank you

Nice information, thank you for sharing it.
