Problems 2 weeks into flowering

[Tiflis]

Hello everyone
I need your expertise to confirm the diagnosis please.
Some info to help you help me :
Strain - DLA 7 ( by Bodhi, Old Mother Ghani x 88G13HP )
Soil - FFOF + added perlite
Nutes - FF Trio( Grow big, Big bloom and Tiger bloom, somewhat old so might be expired? ) I used plain water until about 1st week of 12/12. Gave her some grow big to supplement the N during the stretch and some Botanicare Cal/Mag, but deficiencies were already starting to show at that point. I also think my HLG 135 light was close enough to have caused some heat stress. ( Clip on fan arriving tomorrow so that should help with that, I have also raised the lights to about 20" from the main cola )
Temps - normally 73-75 with 45-50 % RH, but everything fluctuates somewhat due to tent being in a laundry room.
She is most likely going to need watering or feed tomorrow, so I'm trying to figure out what the best thing would be for her. Just plain ph-ed water or feed some more.

Based on charts I've been looking at and my research, I'm thinking there's multiple deficiencies going on here. N, Potassium and probablu Cal/Mag + the heat stress but that shouldn't be an issue anymore.
Thank you all

Might be a ph issue with multiple lock outs. I would give them plain water and see how they respond. Those messed up leaves won't get better though, so watch the new growth. I don't use those nutes though since they are chemicals. Big Bloom is the only one I would use though since it's organic. I'm not a tree hugger, but am trying to keep a no-till living soil that needs little work to maintain.

I wouldn't feed it until you PH the soil.that may not be the problem but I wouldent start throwing anything else at it until you know where the PH is at first.You could go from bad to worse.It just takes a few minutes.If its acidic get that back in place first before you do anything else.Like padawan said those leaves are gone watch the new growth remember in soil it may take a few days your feeding the soil not the plant.I think often people try to feed the plant and mess up the soil in the process.

That my friend is a plant that wants more food. I would bump the ppms w a solid “base” nutrient by 100-150, remove the effected leaves and watch closely for signs of progression

 

[Justkickinit420]

Also foliar 5ml calmag and 2gram epsom salt per gallon (do the math of making less) and that’ll turn around overnight.
Defiantly remove effected leaves and watch for progression no matter what you do

Needs more P and K? Like @Gond00s asked, what is your current nutes ppm? I use Foxfarm trio too, and have seen this before on my indica strains which I have read need more P and K...

 

[ColoradoHighGrower]

Not seeing purple viens or stems, so likely not a mag def...

I have no idea, never used a PPM meter.

I was thinking that, because I didn't bother with PH up until the end of veg. You know, soil being able to buffer and all that crap. I know there's no saving the leaves with necrosis and I barely used them nutes. She was started in a small nursery square pot, then up-potted twice with fresh FFOF.

Thank you everyone for chiming in. I was leaning towards flushing with 2 gal of clean ph-ed water and see what happens. I wouldn't be able to feed for another 3-4 days, but I'm thinking I can foliar feed if I have to. She was a beast of a plant, so that makes me think she's hungry too. I'm conflicted so think I'll play on the safe side.

I'm hesistant to remove the effected leaves, because they're not totally dead. Thinking to leave them for her to use up all of the stored energy.
I can still watch the new growth

Hi Tiflis

What size pot are they in?

Tell us how you have been using big grow and tiger bloom for the last 2 or 3 weeks?

How many teaspoons per gallon of water of each and how often did you add these nutes?
Meaning how many times did you give the plant water only between feeding the nutes.

Hey Kushash
Think we were in a party cup contest together last year, that was fun!

I've got 2 plants, both in 3 gal containers.
Dla 7 was fed around 5 ml cal/mag to 1 gal water for first feed, after I noticed the rusty spots showing. I honestly can't remember the exact order of water/water+feed, but I know I gave her cal/mag + grow big once during the 1st week after the flip. Haven't used tiger bloom at all. I should mention, all this stuff I'm using is like at least 5-6 years old. I also did not have a fan in there, and HLG QB may have been a tad too close. She got stressed out from that too. I have since taken care of that problem, so hopefully I can finish these ladies out ok. I always run into problems into flowering, more so using LEDs it seems, but I've always managed to salvage some decent stuff in the end. Except for that one time...crispy fried using Tiger Bloom, hence why I stay the fuck away from it.
DLA got watered yesterday, 1 gal clean ph-ed followed by 1 gal water + 5ml big bloom. I was going to not feed anything, but big bloom calls for 4 tablespoons for general feed, and that's like 60ml. I think 5ml is fine. In case I'm wrong and she's just hungry. She was a beast, until I slowed her down.

Sounds good, I thought the pot was bigger than 3 gallons.
Too much Tiger bloom can be ruled out.
5 - 6 years is pretty old, I think most bottled nutes have about a 2 or 3 year expiration date.
Big Bloom can't hurt even in the larger quantity of 4 TBL.
It's a pretty big plant for a 3 gallon pot.
Might be a PH issue but I'm wondering if she is hungry with the feedings mentioned.
If she's been in that pot for 4 weeks or more I would think she's hungry.
Not sure if those old bottles are helping enough compared to what fresh bottles would do.
