New to hydroponics, assistance needed

hey lynch, did you adjust ph?

Yes it's at 5.8 currently

 

[PK1]

water temps should be between 66f to 70f but the temps aren't the reason of the leaves.

I'm waiting on some heaters... they seemed to be doing great a few days ago. Could this be a lockout of some sort?

I don't think its a pest issue, i am thinking phosphorus, due to the lower temps.
what is your ph solution?

 

[PK1]

did you recently change rez water or add nutrients?

 

[Lynch_Ironside]

I did a top up on the 1st changed out 5 gallons ppm from 340 to 680
Should I do a reservoir change?

Don't need to change the entire rez, but do a 50% change and add your water resource.
Big jump from 340 to 680. also, watch the cal-mag as that could of caused it

When I adjusted the ppm on the last partial change I had 60 ppm of cal mag before adding nutrients.

i'm not a 10 bottle type of guy and really can't get into which to add and what not.
Simple MC for me however, i know @Aqua Man or @tobh know these bottles better than i do

Sigh.... thanks for your input @PK1

@Aquaman could you bring up to add a thank you emoji to the emoji;s on the post.

where the laugh emoji is

 

[Aqua Man]

63f way to cold... ppm is good around 600. 68-72f. 72 will give faster growth.

I'm with @PK1 Cold root temps and doesn't look like pests.

Look along the branch part on the underside of the leaves with at least 60x magnification, they bury themselves in there .. after reading ur post I looked at mine and I'm pretty sure I have the damn things as well

Update
So the other day my heaters did not show up and with the plants looking worse by the day I decided my fish could live a few days with out theirs.
res temp now sitting at 72
I still think it’s spreading. I left a few of the affected leaves on they have become dried and crunchy to the touch.
i plan on going through and trimming out all fan leaves that are showing these issues. I didn’t want to further stress the plant but the leaves are dying anyway so don’t see much benefit to leave them....
The more I look at the plants I’m realizing that it has really spread. I’m seeing early signs on most of the leaves.
this really sucks
Ph dropped to 5.5
Ppm raised to 700
Topping off res today with plain ro water about a gallon or so

 

[Aqua Man]

Ppm looks a bit to high IMO

 

[Lynch_Ironside]

Ppm was 640 after the top off.
I removed all of the plagued leaves and any other leaf that looked suspicious.
Definitely don’t think it’s insects or a nutrient problem, light, water, exchange, circulation, reservoir or vpd.

So that leaves fungus right? I’m thinking if it pops back up I’ll hit them with southern ag spray? Idk still researching

Honestly they just look like they are over fed... can be many contributing factors. VPD, nutrient ratios, genetic needs etc. Im thinking dial back to 450i-500ppm.

ppm at 700 with ph at 5.5 should not cause this. Did you redo your rez water and brought the calmag down?
i know you said the roots look okay, but double check them. i've got a feeling this is a lockout.
I just found this online from another site and thought its very nicely done.

Nice, love a good chart.
I did a change out the other day, Calmag was Added at 110-120 ppm
No flora gro added with this res change only bloom and micro. 5 grams of epsom for 10 gallons total. Roots look ok. Don’t smell funky or anything... kinda smells like a fish tank
thought it might be rust fungus but nothing wiped off the leaves when rubbed
After looking at the chart I’d say it’s a calcium deficiency but I don’t think that’s the issue. I’ve been very consistent with the calmag throughout this entire grow. I’m always between 110 and 120 ppm
