Hope this is right place to post lol. Transplanted 5 plants about 2/3 days ago so growth has been slowed fed them last night and woke up today to the tops of the plants being a lot lighter than there were yesterday. Moved the light up few inches to be safe for the moment.
There under a 400w MH, in coco feeding canna a and b, ph 5.8/5.9 ec 1/1.1

as shown in last picture the leaf one node down unaffected. Photo 2 probably shows the best photo of the issue.

Feeding them - 1.5ml a and b per litre, 2ml rhizotonic per litre, calmag added to water to get ec from 0 to 0.3.

yeah not saw much development in the last few days. i just changed from using ph testing strips to the ph meter for more accuracy.

I'm in the same boat man I have the strips too but to actually tell a shade different is pretty hard I just purchased two vivosun meters and the strips so I can be sure .
 
I’m new as well so ❤️ I just got my ph and ppm meter still trying to figure out the ppm . Anyway I was wondering if you got any answers to the original question. nutrients or light ?

Yeah I use the bluelab meter getting there in the end haha, was told that it was just the new growth starting up after slowing down after the transplant. All happy and normal so far just cupping on new growth not sure if normal.
