Curling leaf

In the absence of knowing otherwise... Best to purchase a quality PH meter and test your soil to determine the correct PH. Should be somewhere around 6.5, as 7.0 is considered neutral. My experience is that without an acid neutralizing amendment such as agricultural lime, the soil will go acid, at which point the leaves will drift toward a pale avacado green. More fertilizer will only tend to kill it faster, not to mention the risk of overwatering as you desperately try to feed it back to health. If the plant is struggling it may need repotting. Avoid excessive light, lest the plant become driven to exhaustion.

Either from rubbing pot aka wind and mechanical damage. Or overwatering in past, new grow dont show any signs Plastic dome could boil them too , but all in past. Good luck !

if that shit continues on new growth, just trash it -- whether a retard or disease is irrelevant at that point. if it grows out of it... all is well. New growth looks fine.. so i'd be patient and see how it goes. in my expereince, ongoing defective growth is rarely a good plant in the end. i've pushed through with plants with fucke dup leaves and always felt it was a waste of time. YMMV. But, sometimesm those initialy leaves just simply fugly... and it grows fine after that.
