PLEASE HELP !! I need advice FAST

i have a plant that has nutri. burn on the end of its leafs, but now i have 3 leafs that the stem went softer and the leaf is hanging down now. the leafs are not dying but i need advice asap please on how to fix this if i can and what will happen to the plant.... THANKS !

Need lots more info Lights temp age dro or soil you cant ask for help and not give all your info if its soil FLUSH pure water wait 2 days water a few times plain water slowly start your plant back on nute one eight strength and slowly work up to half only nute on every 2nd or 3rd water tho

ok well i dont have all the answer to your questions but heres what i can tell you its good plant soil temp is between 70 and 80 degrees 24/7, i use miracle grow and yes i do need to flush the plant out cause the nutri. are killing it thats the answer ive been looking for all night long. the light is a 2 foot long floresent light with a soft white in the room as well just not near it. i use tap water and i let it sit out for 2 days after i boil it. thats all i can tell you

Why are you boiling your water? Are you pulling it out of the Ganges or some shit?
If the water is bad to the point where you need to boil it then I would suggest using bottled water. Are you using miracle grow soil ,just the nutrients or both?

As far as the info you thats the main one SOIL you need to be carful with MG nutes if your two heavy on them they will burn badly. nothing against it but i will only use small amounts of it. if it is nute burn you may want to put them under a 18\6 they will need down time to recupe from the trama and stress if your plant stress to much it's more likly to be male or hermy so treat it better than your old lady(hope mine dont read that part) you know what strain or good ole baggy? how old is you(fingers crossed)girl? hope i helped just dont over care for her many firsttimers have that prob!I know i did on my first 2 solo grows

oh to go with what shreeder said by boiling you are pulling any oxogen out of the water that may be in there go get a 5 gallon fist pump and small airstone to put in your water for 24hrs will speed up the declore prosses and keep ox in the water for the roots what's the ppm on your water?
