Brown dead leaves started after flowering! Nutrient defficiency?

[slimshady]

Hey guys I have a thread in growing outdoors with pics and all but heres what I have going. 3 plants about 2 months and 3 weeks old. decided to try and flower one. Put in the shed with a small fan blowing to keep temps cooler. after 2 days the leaves in one section started to brown. I thought it was the fan and turned the plan the next day but same effect. So i stopped the flowering process and all three are just outside, its been cold three days straight, about 60 degrees and one of the others is looking like it might be dead and the other one is strong still while the one i tried to flower is being hurt by the weather a bit. Ill just hope for the best with the weather.

However now back to the flowering plant, i asked in the other thread what may have caused this and they said probably because i used miracle grow twice at 50% throughout vegging. They also said it sounded like anutrient problem because thye need a specific amount when you start to flower otherwise they can die. Now browning leaves and a lighter green plant is what I have so it sounds like Nitrogen possibly?

Please help me out here with what the problem is and what i should get if its fixable or just trash everything? thanks

Your leaves will turn yellow when N is deficient.

we need pics,

dont feed with any nutes and give her a good watering and see if it wasnt nute burn. the new growth should be green and healthy but may take time to come back strong so be patient.

the browning with yellowing says its nute burn.

Hey guys I have the pics in my other thread. I think the cold got to one of my babies, its pretty much gone for good unfortunately, one is still very strong, a monster and the last one which is the one i tried to flower is still a bit browning and has dead leaves but looks like it will make a comeback, what i will do is wait another week or so until i think flowering is ready, i will take updated pics and post them for you all to see and give me your opinion and i will take it from there as round 2. thanks guys!

Are the leaves curling upward? Good be K or Mg deficiency. Otherwise, if its at the tip of the leaves, its likely nutrient burn.
