Hey guys
Within the last couple days I've noticed abit of twisting and abit of darkening of the leafs on my plants also on one in getting like a light tea sort of stain near the tip (2 leafs) also one or two leaves on another plant are abit droopy
I'm using canna coco a and b at 2ml each per litre and plant magic calmag 1ml per litre. My surface temp looked abit low at about 19/20 oC so I think it was time I lowered the light
The leaf twist looks like ph swing to me. I've seen it a few times in coco. your checking the ph before every watering? Even if you checked the ph last night and you want to water this morning. Recheck it. The plant comes back but the leaf stays twisted.
