Early N deficiency?

[Delty]

Strain: Dark Devil by Sweet Seeds
Tent: 90cm x 50cm
Light: Mars TS600*2 (only one currently running)
Medium: Canna coco coir, perlite
Nutes: Canna Coco line, currently following light feeding schedule to 0.8EC
Climate: 24c/75f 50-65% humidity
Day: ~15

Plant started to come on strong in the last few days and had a spurt of growth and looked in good shape, so I lowered light to ~20 inches. In the last 24 hours or so she has started to show some fading to the area between the veins, you can see it more pronounced on the lower leaf in the background. The plant is incidentally a tri-leaf!

I was planning to transplant her to a 3gal pot about now but I want to try to clear this up first. Is this N def and how do I overcome? surely it's not underfeeding? PH has been at the 6.2~ range.

Thank you very much for any help

I would bump my nutes up a little bit, make sure to water to 15-20% runoff and lower my ph a little.....I'm not the sharpest tool in the shed, so please get a second opinion before doing anything drastic

What is the PPM and source of your water?

Sorry I thought I had replied to this, but still need a second opinion the below:

water ppm is 25-40, rainwater.

Upping the EC slightly to 0.8 certainly helped and the had another spurt of growth and the leaf discolouring *partly* fixed.

However some of the leaves are really weirdly wilted and misshapen (furthest from camera) and I’m considering popping another seed to replace her, what do you think? I also had bizarre leaf issues the only other time I tried to run this strain - never had anything like it on Sweet Gelatos I’ve run from sweet seeds
