Super small autos and terrible grow

Hi, everything is going wrong
These autoflowers are now 18 days from germentation and 16 days being in soil. If anyone here has seen my last thread where I questioned if I have septoria or not it turns out I do. Every single set on the bottom leaves of all 20 of my plants have slowly started getting spots and working its way up. So I went out and got myself some copper fungicide hoping it will stop the spreading (first spray will be today). Anyways my autoflower as you can see are absolutely tiny they have a good green color besides the bottom leaves which is septoria.... How much small are these then normal autos and also one of them has white hairs already did it really just start flowering? Any advice would be great at this point.


The septoria has taken a gigantic shit on my plants. My purple kush is only 13” tall at 50 days of ve with 6 sets of leaves. I dont know what to do because I was hoping to get rapid growth before switching to flower because since I have super slow growth I feel like this needs to get fixed before I switch it over but because of timing im switching to flower on the 21st regardless... My whole grow is a mess. Not a single plant is getting rapid growth.... All so small. One last thing how undersized do those autoflowers look for being 18 days old?

Conditions
Lights on temp - 80
Lights off temp - 70
Humidity - stays around 50 lights on and off
watering ph is - 6.5
soil ph - soil say incubated for 6.2 on the bag and I bought a soil ph meter off amazon and i think its super inaccurate or defective. Ive checked soil in about 15+ different locations and the soil im growing it an apparently none are below 7 which I know is 100% false because i wouldnt get growth with a PH of 7.7 which is being read in my grow tent. Soil is from same soil bag from my first grow which did 100x better. I got 65G from 2 autos for my first grow(not terrible).
Growing with advanced nutrients - I have a whole line but ive only used the connoisseur because I want to fix this growth before I add more shit. Like everthing looks decently green just growing so slow!!! Maybe its the cropking seeds. Looking at there recent purple kush reviews on ck more then 50% of them had complaints but the autos im not sure what to do....

Looks like picture one it’s over water. Lack of dissolved oxygen. Suffocation of roots. First signs of low ph as well starting to show symptoms of lock out of cal mag.

Second one is ph is to low the plants look like they are being deprived of cal mag.

Get a better ph pen or stick with strips or drop.
Better a slight higher ph than lower.

Cheers

they were actually underwatered, I over watered my 4 purple kush and i let these guys get too dry. I watered them just before i took these pictures, you can still see some spots where its bone dry the water came out instantly from the bottom when i watered them today. I know its not any better then over watering. Also they arent calimag deficiency’s. Look up septoria, I have a really bad case of that going on. It looks like a sever case of cali mag deficiency but I gave my PK a high dose of cali mag and it did nothing, the septoria just keeps speading up. Also its not nutrients lock out on the 9 auto flowers as they never been fertilized. Ph might be a possibility. I have a ph up/down kit for checking liquid ph but not a soil pen or kit.

pH and overwatering

Soil pH meters are NEVER a good idea. Do a runoff or chemical test.

Do a slurry test not run off.

It's not a disease.

It's grower error. If they were dry then it's chronic under watering.

Over or under watering will cause pH issues.

so out of my 4 larger plants the purple kush I did a watering on two of them that were pretty dry.
I did a PH and PPM test on the water going in and the runoff. I used chemcial test for PH from the PH up/down kit and I used a digital meter for ppm. This is the results.

Starting water PH/PPM - 6.9ph/5ppm

After adding calimagic then advanced nutrients connoisseur its now 6.5ph/550ppm

Run off results - PH was exact same 6.5 but my ppm was 770 so nearly 800.....

This means I have a nute lockout, but from what? Also if I water with just water what should my ppm be?

missing a watering on time has a massive effect on the leaves... It can have you chasing your tail far ages looking for deficiencies.

i was watering too much at first so i was taking it easy on them, dont think i ever let the roots get bone dry, also can they bounce back from that?

Let me see if I get this, your run off accuses higher concentration than the aqueous feeding solution? I think you saturated the soil with nutrients,as eager you were for getting rapid growth. Auto's don't like overfeeding, they're very fastidious sometimes and better off living is austerity, they just strive with sparse feedings and sparse waterings.
I'd flush the soil with distilled pH'ed water and leave some days before adding again a dilute solution of nutrients.

Everything.
Just like you said.

Sorry.
Im gonna say what i can see.

No nutrients.

Plain water only.

Dry it out.

Forget about ppms with soil. Its just a silly number.
Only useful in hydroponics really.
5ppm water. You're using RO? Maybe bring it to under 50ppm, with calmag.

Stop measuring your runoff.

Imho
Stop using those shitty, synthetic nutrients for your soil. I use synthetic nutrients, but only hydro.
It isnt very good at all for soil life.

Plain water only.

Until good runoff

Dry it out.

Repeat.


Good luck OP.

They can bounce back from looking dead....overwatering is as bad as underwatering...
In a way, it can be worse as is also deprives the roots of oxygen.

I would never use plain water, add a small amount of ferts to it...
What happens when you have two bodies of water separated by a membrane with one of the bodies of water having a higher concentrate of mineral salts?

Make things simple ....

1. Buy a PH PEN ... Shitcan the soil meter
2. Use good potting soil
3. Amend soil with perlite
4. Use a simple 2 or 3 part nute line - forget the multiple bottle shit
5. Ph your water TO 6.5 ... Regardless what the bag says
6. PH water when you do plain watering AND when you do your feed mix.
7. When using BLURPLE and or LED , plants will transpire LESS than other light systems.
8. AUTOS want light ( more the better ) .
9. LED / BLURPLE grows require LESS feed. Sometimes up to 30% less.
10. Stick to ONE LIGHT CYCLE - 24/0 - 20/4 - 18/6
11. Water ONLY WHEN NEEDED
12. Autos can stress from watering issues , ph , feed and other shit .
13 . Autos are plant , grow , harvest simple. They do not need boosters , unicorn cum , special water , etc.
14. AUTOS will flourish in 1 / 3 / 5 gallon containers. No need to transplant , just plant seed.

It's a PH problem all the way across - you pretty much are trying to " gauge " medium instead of " PREPPING " your liquids ( both water and feed ) , you make no mention that you are doing that , only soil meter. Those things are worthless.

You must ph your water and feed so that at the desired ph range , all of the necessary elements are " available " for plant to uptake. Guessing will bite you in the ass sooner than later.

i literally said i checked the ph with chemical which is more accurate then pen. Read my last reply. Ph water in was 6.5 and the run iff water that came out was 6.5. but the ppm was about 200-300 more

Keep ppm under 700

Are you watering until good run off? Mixing your nutes weaker than suggested? Do that and it will help.

Water only for the next few waterings. Daily with good run off.

Also run off pH means nothing. It can be accurate but not always. Different things in the soil can affect the reading.

Mix equal part soil to distilled deionized water and let sit for a few minutes and then test the slurry.
