i wait till the pot is light and dry and then water so i dont think its overwatering
tips of leaves turning brown could be a sign of low humidity and usually doesnt go an farther than that. i cant say for sure thats the problem without seeing it but it souds like your over caring for the plant, it really isnt hard to growok so i didnt give em any nutes but their tips are turning brown and twisted after the transplant in to this new soil everything was going just fine, they recovered and now again the same shit, what can i do now
