Out of the tap it's usually 6.4

Id raise it closer to 7 see if that fixes it....cut back on watering too. If you are checking this plant everyday...no need to give excess water

I'm not positive ... but i believe its a P or K burn ...... my last little ones showed the same on a few after a strong balanced feed

Is a burn even possible considering they haven't been fed anything but water?
Soil too hot maybe?

its possible ...... it could be ph ..... but i grow in mostly soil less with very little nutrients ..... for example my vegetables i start in it i have to feed right off the bat ....... my PH is on point and mix is buffered anyway ...... so if i only get that when i feed a heavy 10-10-10 i would assume it was a slight burn ..... like i said though **** disclaimer **** im not positive

Thanks, I've looked at this chart and the closest thing I see is a boron deficiency?

i never ph and my water is 7.4 with a ppm of 500 dead salts i use biobizz light as it has no nutes in

Is it only some plants that do this ?
have you tried cutting it down with just plain peat or coco maybe ?
Ive never seen or had a chance to use this soil and the search i did showed mostly UK journals
