What strains that? Have u checked ur pH that's going in? Is it light burn? is it on any new growth? Or just older growth?
DINAFEM CRITICAL+
1x plant
8L pot
100% brick coco
pH in always 6.0
not light burn as it’s affected OLDER leaves at the sides of the plant that are more than enough distance away etc.
It’s calcium.
I suffered with it using HPS but managed to increase Calmag by 0.2 to sustain any issues, my source water doesn’t even list Ca in the report from supplier lol source water EC0.2.
this time I’ve used brick coco that I rehydrated with straight tap water. Could have caused it as no
buffering.
didn’t buffer it just straight feeding right away.
I’m pretty much certain I’ve stopped it now but time will tell.
I’m not overly concerned.
I don’t freak out with issues like this.
I’ve seen them before in my room was wondering at what point they would surface again due to me running cooler and switching to LED.
At present I’m hand feeding Calmag once a day at 0.6EC pH6.
since I’ve done this EC0.8 going in EC 0.9 coming out.
before I adjusted it was EC in 1.0 EC out 1.4 which is usually the sign something is happening in the coco.
