Seems all my leaves are yellowing now ughgh

It’s my first first auto grow. In the front I have WOS Neville haze auto at day 56. In the back left I have Seedsman blueberry auto at day 68. Back right Dutch Passion Night Queen auto at day 68 also.
3 gallon pots—2x2 tent—spider farmer sf1000–bottom 1/3 of pot is FF ocean forest and top 2/3 is FF happy frog. I’m feeding FF big boom and tiger farm alternating each water. I been feeding 1/4 tsp cal mag every water. I was giving myco up til 2 weeks ago. The blueberry i started flushing last week, plan to harvest on day 75ish. The haze is coming along fattening up and stinkin like lemony terps, but flowering time says 90 days, I’m thinking it’s going to finish up a little sooner than that, but still a few more weeks. My leaves have been showing rust spots since a few weeks back and now leaves are yellowing more and more every watering. I know leaves will start to yellow during flower period but I don’t think they’re supposed to this much yet. I’m worried my buds aren’t going to finish right if the trend continues. The night queen is weird af. Leaves are skinny, rust spots, yellowing, little drooping. It started flowering the same time the haze did but seems like progress has come to a halt. A lot of white hairs but minimum trichomes and not much change happening as far as fattening up. No smell on her. Anyone tell me if my plants are doomed?

You’re deficient on nutes. You need bloom feeds and lay off the cal mag. That’s not why you have spotting.

Ive been feeding tbsp/gal of big bloom. And then 1.5 tsp/gal of tiger bloom. Alternating each feed every watering. My ph has been an issue for little while .. I’ll water with 6.5 and my runoff comes out sometimes as low as 5.3. So my last few waters I’ve been flushing each plant with a gallon of 7.0ph distilled water followed by a gallon with the nutrients. The water run off started to raise but still I’ll get low as 6.1!

Try watering a couple of times. See if the problem disappears or worsens. But your pictures say deficiency.

Over feeding bloom nutes especially makes the soil
Acidic.

Looks like pH issues. In fact when u get multiple deficiencies at once it’s mostly likely pH.

Also too much P/K yellows the tops of the plants.

It looks like you have water dripping down the side of the tent!

I think your rh is too high, you're overwatering, you're overfeeding, Let them almost dry out then water them just a little bit or you will rot the roots. You don't even need run off all the time in soil. I used to happily feed a 6 litre pot just 500ml of water once per day when using led. This grow can still end up going very well, but you have things to address 1st.

It was already deficient and got worse when you flushed.

Why not feed big bloom and tiger bloom at the same time as instructed? I’m confused on that

you need plain water between feedings. You also never mentioned how much TB and BB you’re feeding.

I thinks I have the same problem..
ok so I got two plants the one on the left is a royal drawf auto, right is the moby dick xxl.

2x2x4' tent
4" exhaust and intake with a carbon filter
Sf1000= 100 watts led
3 gal fabric pots
Dwarf is potting soil and coco
Moby is only coco
Feeding ff trio 50% every other watering, watering every other day 1 gallon about ( half that for the dwarf)
Temps run around 65 to 83
Humidity 40-60
Ph is ranges from 5.8-6.5 for (moby) and 6.2-6.8 for(dwarf)
We are in week 5 total. Just started flowering about last week.

I think its was a cal mag def because I might have forgot to put it in. So I added a full dose with the regular water. Please help this is my first grow.

I thought i used to many nutes as well so I flushed it last time.
And sry not trying to steal ur post it just seems like we have the same issue

That water was actually from my co2 bag that slightly dripped from a rip but I patched that up. My rh is 38-48. I probably have been watering too much just trying to balance the ph . My run off is always much lower than what I put in. As far as feeding I’ve been going half dose with foxfarm trio. I jsut don’t know how my soil is sooo acidic

Why would my tips have burnt if it was deficient? Also why would my soil be so acidic if it was deficient? I was mainly flushing to try flushing out salts and raising ph

The bottles stated alternating between waterings. So I took that as BB one day then TB the next feed. I’ve only been feeding them at 50% as they’re smaller autos

I don’t know what to do at this point, my leaves are curling and dieing

I has a simular problem on my first grow. i changed lights at the start of flower to hgl q boards and had them up to bright and burned all the top leaves. looked much the same as these pics.
