First grow on coco. Is this a nutrient issue?

So .. on the right is the one in canna coco, the same as last pics. The one on the left (and the pic on its own) is exactly the same seed planted exactly the same time but is in canna terra professional plus. Looks totally different from the one in coco and leaves a much lighter green. Look like the coco is the winner so far.

Just one leaf at the bottom what a crazy outcome I really hope mine will thrive at least just as good!
 
Seeing a few brown spots on several leaves. Not sure if it’s light burn / wind burn or some sort of nutrient deficiency. Any help much appreciated

What is the soil ph at this moment?
I found out that some products like mammoth p will lower ph, I was feeding at 6.0 and next flush it was always 5.5 and I had to start watering at 6.5 to get to 6

seem the PH is too high. I have been feeding at between 5.8 and 6.2. Not sure what ph is showing 7 unless issue with the tester.

If you think there is a buildup in the coco, mix your normal feed strength and pH and flush with that until the runoff is about the same as the PPM and pH of your solution. If there are no signs of a buildup or anything keep feeding at the correct strength and ph.
 
So the other plant, same batch of seeds, planted same time as the one in coco but this one done in canna terra pro plus. Issue is that the buds are so airy / fluffy. No density at all. Wondering if they will ever fill out.

My thoughts exactly. Should I start watering with a much lower ph? Or just carry on as is considering the plant looks ok? Really strange one.

I said what cause I didnt understand what you said but if your saying you feeding at 6ph and it becomes higher Its a very simple fact. The plants it is absorbing nutrients from the soil and this raises ph, you wanna try to feed a bit more frequently till runoff I can see it from the pictures that she could use some more feed.

You've got a long way to go on that one before she's done. So we'll find out together! Seeds are like siblings they can be very different. She looks very good, just keep running them and see where they go!

Growing in the Mojave during the summer my buds would be less dense so are you a bit warm there?
