Help!! possible ph problems.

Sup guys, doing a micro grow using the 12/12 from seed method and things we're going good. Now into flowering her fan leaves have Brown spots and tips on em. And Today I'm noticing the top bud is turning a little bit brown ( could be light burn idk ). I wonder if the ph is off. She's in fox farm ocean soil and I only feed her tiger bloom. I adjust the ph to around 6.5 but when I test the run off its like 5.0 I think. I use the ph kit with color results. So basically my adjustment was greenish and my run off was more orange. What am I doing wrong and what should I do?
Thanks.
P.s I use less then half of what's recommended for tiger bloom.

no need to use tiger bloom when your starting in FF. it's got fert already. since you're flowering already, it's a good chance you could go the rest of the way without any more fert.

The one thing that I do notice the most is the downward claw on most of the leaves. Nitrogen toxicity perhaps? I don't know much I just figured I could throw in what I observed.

Looks like a calcium def. Probably from the ph being too low.

Can you measure the ppm or ec of the runoff? The ph will get too low if there is too much nutes in the mix.

I transplanted her 33 days ago. I figured the soil was used up by now. And I flushed her like 3 times to get rid of the Nitrogen hints The Claw.

Nope. I decided to lay off the tiger bloom due to lack of experience in mixing. Don't wanna mes a g [gd thing up. I used 1/2 teaspoon, then 1, then 1 1/2 teaspoons in 1 gallon of water then give her half. Idk least ph will go back to normal when I stop

Yea I flushed her few times to get rid of the N. Someone told me the leaves won't heal when corrected.

the leaves won't heal if they go brown. yellow can heal.
