Deficiency during flower

Hey guys, I'm on day 40 now with my Northern Light Blue auto from Delicious Seeds.
The fan leaves are getting rust spots, which I thought could be calcium deficiency. I got some calmag but it hasn't helped. I also gave a light feed of tiger bloom. I'm using ffof under the hlg 100
ThanksIMG_20190709_074011842.jpg

Hey man I'm a first time grower nearing the end. I had the same prob with one of my NL as well, pretty bad case that even started to affect some tops(see pics)
No idea what the issue is exactly but I made my drain holes bigger on it's pot, gave it a good flush then started back on nutes a little bit weaker than before and cut off most of the worst leafs which seemed to cease the problem.
Good luck to you and I hope a vet with more knowledge can chime in with more info than I can

I'm kind of thinking it might be a phosphorus deficiency, so I'm going to give another feeding of tiger bloom and hope it helps! This my first auto and only my 3rd plant. I think i stunted it from heat before I got my new light but I'm hoping it'll still stack on a half oz atleast

If you are waiting for the damaged leaves to return to normal you’re wasting your time. Watch for newer damage and the newest growth. That plant has some real problems. Appears overwatered at best.

Yeah still spreading. I'm using tap water ph'd to about 6.5, I say about because I don't have a meter, just the pH test drops so I'm going by color
The calmag is also 1 tsp per gallon and I pH after I add the nutes

How many times have you used cal/mag & tiger bloom with that plant? No other nutes right?

The tiger bloom alone already has calcium, along with tap water and cal/mag it should have at least slowed down, since it didn't you might have other problems not related to ca/mg, backing the light off like hotrod said would help slow the progression, a few of my buds run hlg100's at 20" mid flower, so yeah 15" sounds a tad close.
