Splotches by veins, leaves curling up, yellowing

I know I have a nitrogen deficiency. I think I have about 2 weeks left, and I hope it will be ok till the end.

I dont feed it much. Once every couple watterings. I use Advanced nutrients big bud, and molasses. I also just gave it some other bloom fertilizer 2 days ago. it was 3-10-5

or something like that. I have to go look. But, a normal bloom fertilizer.

I was thinking it was a boron deficiency, and calcuim maybe?? But, the leaf tips are burnt. There are dead spots on leaves, new and old growth.

Now, today one of the yellow fan leaves that was yellowing has curled up. Usually they dont curl up when they die like that. Or, they havent for me on this plant.

Is your PH value as it should be? - if so how is the temperature. Plants can do something like that if it gets too cold in the room or water is too cold.

I am not sure about the PH. I should go get a tester. I flushed the plant today, so maybe that will help.

It isnt too cold.. It is about 75 or so..

I added pictures.

Yes - check the PH-value. I think that's where your problem is. PH-value is important for your plant to take up all the micronutrients.

Now that I think of it.. I think I just burned them with nutes..

I will check the ph tomarrow.

Thanks!!
