I'm stumped, what am I doing wrong??

Hi everyone. I have been having issues with this plant for the last few weeks. It is still in veg and is somewhat stunted I think although there is still growth happening. I really want to get this issue sorted out before flipping.

This is a Godfather OG monster crop from my last grow and the mother did very well. The only thing that changed was that I went from the migro array 4 pro light (in a 4x2) to the Mars hydro fc3000 in a (3x3)

The issue is, the leaves are not growing very large before getting what looks like nute burn and then dying off. All older leaves are crisping before getting large.

I thought it was nute burn so I dropped ppm down to 500 for a week but the problem didn't get resolved. I then started thinking it was a nitrogen deficiency, so I increased the nutes back up to 785.

Here is my setup/stats, everything appears to be dialed in from an environment perspective

Tent- 3x3 grow area
Light- Mars hydro fc3000 (50% strength)
Light height- 12"

Daytime Temp- 78
Water temp- 67
Humidity- 55%-65%
pH- 5.8-6.2
Ppm- 785
Nutrients- full canna line with hydroguard and cal mag


Any thoughts on what it could be? Or something else to try?

Looks like light stress, raise your light to 24 to 30 inches above canopy.

How is the water you're using and how much calmag? And unless you're keeping the light 6"away turn it up

Edit: didn't see you were 12" if you can get it to 18 and turn it up you would also benefit from the heat

It would be 550 right in the middle. I've got this exact lamp. He needs to feed canna at full strength and cut out the calmag. It's definitely not the little fc frying the plant

light stress raise it or dime it.... in veg dont need as much light as in flower .. 18/6 in veg plant can't take all that light. unlike in flower where using more light at 12/12 ..

It really depends on how many hours it's on veg,
18/6 and its likely fine light wise, 24/0 and its not.
Plus a few extra degrees f wouldn't hurt.

Did you not see all the tip burn in his plants? That's not a light issue, it's an over fertilization issue.
Over nuted would be dark green, not bleached as is frequently common when given too much light. She can't keep up with the light being given , back off the lights till she's ready.
And yes you're right light stress stress can cause burnt tips. The curling leaves, bleaching and short internodal spacing also tell you it's light stressed.
Also, notice that the leaves towards the bottom are dark green the furthest away from the light. But no, it can't be light stress, for you and your merry group have proclaimed it, despite all evidence to the contrary.

I don't have any merry group, so I'm not sure what you're referring to. The leaves are not going to be dark green in a nute lockout situation due to overfeeding. I've also never seen leaf tips burn from excessive amounts of light. 12 inches away at 50% shouldn't be an issue.
