What you have read is complete and utter bullshit. Just another myth perpetuated by ignorant people on MJ forums who know nothing about growing healthy plants.
To fix your problem, you just give it more N. It wont fix the affected leaves, but the unaffected foliage will remain lush and green.
The reason you experienced N deficiency is because Tiger Bloom doesn't have enough N in it to maintain healthy foliage.
If your leaves yellow, fall off, and die, then your plants ability to photosynthesize is reduced. When it is reduced, your yield then goes down.
If you can maintain healthy foliage until harvest, you will have a chance at the largest yield possible. I say chance because there are many variables that affect yield, but healthy foliage is the most important one.
Give them some Grow Big or any other fertilizer with sufficient N, and you will be on the right track.
