It's probably just nothing man and will continue to grow well. Sometimes they have like birthmarks while they emerge from the seed

Thoughts, should I be concerned?
One of my plants is developing twisted and spotted leaves. Is it just to much nutrients or something more?

Fungus or deficiency?
I have these gals growing outdoors and have a few leaves that look like this. Appeared after multiple heavy rain days. Applied nutrients yesterday so I still need to wait for the results. Is this a sign of fungus or deficiency?

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Whats wrong with her?
I cant tell what's wrong with her. I recently upped my CalMag nutrients cause I originally thought this was a Calcium deficiency (full nutrient breakdown in diary). I dont want to hinder my harvest so any insight?

Possible manganese deficiency?
I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?

Brown Patches on Older Leaves
Slight yellowing and brown mottled patches. Only on one of the two plants and they’ve been treated and fed exactly the same. On some older fan leaves, no signs of anything on new growth. Anything to worry about at this stage? Maybe just a sensitive pheno? Any advice appreciated.

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

Damaged leaves
I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency? Or do I have another problem? And is 1 ml CalMag Agent enough to counter it? Dont wanna risk anything so close to the goal...
