Need help all plants showing symptoms

Hello,

Outdoor grow
Coco soil less
25G fabric pots
Feed GH flora series with cal-Mag
everyday 4 gallons of tap water that sits 24 hours per pot about 20/30% run off

Cal-mag 1/2 tsp per gallon
Flora micro 1/2 tsp per gallon
Flora bloom 1/2 tsp per gallon
Flora grow 1/4 tsp per gallon
Feed at 5.8 PH

Little back ground my plants have been nothing but prefect that actually grew to good and I ended up having to drop the 25 gallon fabric pot into the ground as they are over 8ft.

They have now been flowering into week 3 and are starting to show signs of what I think is mag issue.
we have had a supper bad heat wave the last few weeks with the high in the grow area at 103f with 43% hum.

Some of the plants the sativa seem to be doing better however all of the plants are starting to show this yellowing that seems to start at the bottom and working it’s way quickly to the top.

Any help would be appreciated

Thank you,

Any one have an idea to this one please?
This is my first outdoor grow I used to grow indoor like 20 years ago in soil though.

Thank you

It looks like spider mites. Have you looked under the leaves with a microscope? Do you see any webs?

I have looked for spider mites I did not see any. I have a ton of active lady bugs, green lace wings and praying mantises.

I have ran into spider mites once a long time go in door grow and the webs where pretty visible.

I will get a better microscope and take another look.

Thank you for the reply

Took another look today and did not see any signs of spider mites. Is it possible that I have to much kelp meal?

Maybe potassium really hard to tell. The leaves are pretty dirty as well been got some rain a week back.

Here are some more photos included one of the bud growth that looks healthy

first thing to do is a run off test ......u feeding at the right ph does not mean the coco is at that ph (pour 5.8 phed water tho untill comes out the bottom count to 20 and then take a sample to test )

but the looks of the plan it is little nurt burned and crying out for calmg
back down on the feeding str by 10-15% and hold there for a week then back to what your plan was .......if u can add in B52 and rapid start (this will help the roots bulk up so the feeding will increase)....add more calmag+

when u say tap water are u talking city water or well
city water has herbicides in it to keep roots from growing in ........carbon filter for the hose or fill bathtub with hot water when it cools to room temp the chemical will have evaporated out so the water is use able

Thank you for the help on this.

tap water provided from the city I have about a 100 ft hose that I use to fill up a 45 gallon jug and let it rest for 24 hours ph to 6.0 add nutes and the ph sits around 5.82 I have two ph pens to confirm.

Been doing this since I popped them.


As far as run off that will be a hard one for me. All of my big girls are in the ground now .
I have a few others that as showing the same thing smaller but I can test the ph on those.

The larger ones before I dropped them where showing about 6.2 in the run off. However that was a while ago. And I did a full flush the day I dropped them into the ground.

Since I have posted I have cut down on the nutes and added the Epson salt at 1 tsp per gallon.

I think its helping shall see this is day 2 in.

For the leaves that are showing the signs do I just let them die off or pull them?

i am honestly not sure if the 45 gallon cold water will vape off like it does with hot .....i know it will in a 1 gallon jug but that has a 8% oxygen transfer in the sun which allows the purging.....but i know this filter will do tha job and mine lasted me 3 years before i replaced it

as for your leaves ......the light has already flipped into flowering .......i say if they stay green leave them alone if they yellow up then the plant has no use for it take it off

Thanks again should have it in 2 days.

I was able to test the run off on some of the smaller pots I was getting about 6.1 run off from the 15 gallon pots.

All of the pants seem to be doing better except for one the Alaskan blue she is really not happy and the break out is almost to the top of the plant.

Not sure what to do with her. I did notice as I was looking around the other day a bunch of these little bugs that sit on the main stock never find them on the leaves. They seem to be shooting what I think was eggs out of them. I did notice a few on the other plants but nothing like this one. I do not think it’s the cause but thought I would post it.

You have a potassium deficiency in your first pictures. Your last picture is a phosphorous deficiency. As for the bugs I have no idea. Best of luck.

PS your run off pH doesn't matter.

Bluish/Green=PK Locked out or Starved, that's for you. But completely agree on PK issues.

What city has herbicides in the water?!?

I have purchased the water filter and started using it the last two days. I will start to focus on the deficiency and see if I can get this girl happy again. Her bud growth has slowed but they still look great.
Thank you again to everyone for your help

advance nutrient B52 ........will help the plant and get it back on track

Calmg+ for sure ......the little brown dots on the older growth
chelated iron ......to help get the leaves greener and stop yellowing if that keeps up ...........the chelated is the important part u can buy it for plants or as a vitamin for ppl (crush the pill mix with warm water then pour into cool water feed mix).......i liked the plant stuff just amazon chelated iron and zinc

bump up your NPK feeding amount by 20% every other feeding
rem if u moved the mass to soil the PH changes from 5.8 to 6.5 for best absorption

side tip if u want super crystallized plants look at advance nutrient bud candy / molasses .....with a touch of fox farms cha ching

yah all cities add a combo of different chemicals in the water .....herbicide is to prevent roots from cracking the pipes so often(little tap root gets in but does not grow into a large feeder root and breaks the pipe)......the older the city the higher the amount rem the pipes are buried 80 110 years sometimes cast iron ....replacing them cost way to much so they wait until the break to do any major and that just a new rubber/plastic liner for the section near the break and replace the broken section

if u want to get freaked out look for a old news report about Washington DC water ......pharm grade drugs in the water

All just as I started to get everything back and going I have been targeted by a group of catipilers. I was warned that they are insane where I live and most growers have to pull early. I was treating for them while in veg and also have a praymantis team but they simply can not keep up. I went and bought 6 more praying mantis eggs in hopes I get a few hundred to take them on.

I have been reading up a lot on them but my plants are now in week 4 of flower and not sure I want to spray anything on them.

Last night I spent at least 2 hours killing what I could find never ending.

I use tap water exclusively when I run out of rainwater. I have roots filling 5-7 gallon containers. Don’t believe this herbicide bullshit.

LMFAO!!!

There might be herbicide residue in some city supplied tap water but there is no way in hell that it's deliberately added to it.

Fluoride and chloramine is bad enough tho I'm sure Mon$atan would love the contract to supply RoundUp for drinking water purposes.

The crap some people think never ceases to astound me. LOL
