This is a Gelato (fem), germinated 2/13/22. Explosive growth in first 4 weeks compared to others germinated at same time. Topped after 5th node, and the new stems are taking off.
She is in a 5 gal fabric pot, with approx 2" of Cali Super Soil on bottom, and filled with FoxFarm Ocean Forest. No pests observed. No nutrients yet used.
The tent is 4x2x6 with a Kind x420 attenuated to 25% about 20" over canopy. Temp remains between 72-80F and RH is held between 45-55%. All water is pH'ed down to ~6.4.
So - the opinion(s) I hope to get - (a) what would be the probable root cause of the fan leaf tips looking burned at the top of the canopy and (b) what would be the probable root cause of the fan leaves at the third node (second pic) getting spotty and looking generally unhappy?
Thanks for any feedback;

I hope this is helpful
@Cap Stone - Many thanks for the quick feedback. CalMag ordered and she'll get a taste tomorrow.
I'll post pics over the next several days to see how she responds. (Leaving all other variables the same)

Hi, totally just guessing here so maybe wait and see if others agree before acting.
The burnt tips at the top look like a mild nutrient burn, but you should not be seeing that after 30+ days in the FFoF soil. Maybe the roots have hit the Cali Super Soil and you are getting a burst of nutrients? I am not familiar with that soil so not sure. Assuming it is a mild burn caused by the super soil and not from being hungry, I would just continue watering and keep an eye on things. If she starts getting worse then maybe consider a flush, if she starts to fade in color then she is hungry and it's time for nutrients.
The lower leaf problem looks like a Magnesium deficiency. I would definitely be adding CalMag to your water. I am also growing Gelato clones and wow do they ever like the CalMag.
If your Gelatos are anything like mine, they respond very well to LST but can get very bushy very quick!
Have fun!
