As a general rule, should I cut off fan leaves tha...

Personally i don't remove any leaf till preflower (good or bad looking) Instead of adding nutes at this point- use iron, magnesium and calcium as foliar spray 1x weekly, Magnifical from Remo Nutrients works for me, this will fix leaf problems ;) good luck

You need bigger pots bro 👍

Hi buddy, I’d say keep the leaves on as they store nutrients for vital growth of your plant. Until they naturally yellow there’s no need to remove them. Second, you’re feeding nutrients too early. You don’t actually need any until around the end of your 4th maybe 5th week. So I’d jus feed with normal pH’d water for the next two waterings at least but only when your medium is dry. Try not to give any nutrients till she starts showing signs of deficiencies as you can add the nutrients but can’t necessarily un do the damage of nutrient burn. Getting nutrient lockout at this stage to would be a disaster as you’re setting your plant up for a Healthy flower period. Some of your leaves are curling down also which is an excess of nitrogen so back off them if you want to see improvement. Any questions just ask. Hope this helps.

The fan leaves damage is just a symptom. Removing them won't make the problem go away, just make you oblivious to it, until another leaf shows symptoms. You have a couple of problems to resolve, over watering for one and mild nutrient burn for other.
