is this root rot?

Hello everyone so this is my first grow and I've ran into big problems this is 11 weeks since they sprouted. They're 3 1/2 weeks into flower and they are starting to look horrible my one is completely being taken over it has been for awhile but the other 2 were just fine until recently now they also are turning yellow with brown spots and dying. They are still getting buds but I don't think they're growing at a good rate anymore. I've tried researching and identifying the problem but I'm confused. Just hoping someone out there can give me some advice I really could use it right now. This is the strain Crystal. (White Widow x Northern Lights)

Please I need some advice here

They look to be overfed to me, probably multiple lock outs. What is you feeding program?

Flush pH 6.5, let your soil dry, flush again. See how she is in a week or so after the flushing. I see Magnesium. How is the drainage in those buckets?

root rot is not a big issue in soil, root pests can be. give us the run-down on your grow. very sick there.........

Thats not much veg time, I dont think your plants reflect that. Are you sure about how long you vedged or flowered. Your buckets need to be drained look at them do you see fifty one inch holes in that bucket if not put them there. looks to me like you need to drain them and test the run off water.

I have a hook on some food grade plastic buckets if your interested so you can ditch the homer pails pm me.

That looks like magnesium deficiency or looking at the burnt tips over fertilization or excess salts in the dirt medium. You'll be hard pressed to get root rot in a peat based medium with cannabis. By day 5 even if they are not drinking most of the water would have evaporated.

My feeding is just cal-mag then just water and then I use tiger bloom then just water. My tap water had a really high ph level so I started using distilled water. They are in FFOF. For flushing them how much water should I use to flush each plant?

I vegged them for a month and a half, my buckets have plenty of holes in the bottom

unless boxed doesn't have proper drainage did you see the pots?Holes need to be drilled and water needs to run out

These are the bottom of my buckets

you need to drill up the sides about 1/2 way up the bucket the more air holes the better. looking at the roots in the bottom of the bucket Im assuming those are from seed am i correct?

Go with a bigger bucket

Yes they're from seed. So half way up I should drill some more holes? And I can't go with a bigger bucket lol I don't have the room

Tiger bloom? N is to low and P is to high.....No use of a "zyme" product? Looks like an unstable pH problem or a nutrient lock due to mixing with out water. pH anything going in to 6.5, after you have added your nutes. Be sure to rinse the measuring spoon/cup between nutrient measures, and NEVER mix nutes together before adding water!!! ALWAYS ADD NUTRIENT TO WATER separately and with clean tools!
Crush up some egg shells and soak them in your distilled for 48hrs before you use it.....Looks like low Ca too..(I know, your adding a Ca/Mg).....do it anyway......Add a bio to the soil to help bring the soil back,,,,flush? not the best idea.....If you have to, to feel better,,,,,simply run a low nutrient solution through just till you get a cpl of cups of run off and let it dry out to watering stage....If your going to run the Tiger out till it's gone cause you spent the money on it....add some N in like Floralicious plus concentrate at 10 drops per gallon...or any higher N supplement with LOW P.

Good luck

it could be a ph problem my tap water was really high so I was using about a cap full of vinegar to bring the Ph down and maybe a little tiny bit of baking soda to raise it if it went to low then I switched to distilled water upon suggestion from a seasoned grower

ok so i started testing my ph levels once again after cleaning my ph meter and recalibrating it. I tested some runoff water in the bottom of the bucket and its around a 5.9 which is way low which is probably causing my lockout. Can anyone give me a recommendation on how to raise my ph? And should i still flush? Will my plants recover?

if you have a tds meter test Your run off i bet your ppms are real high I bet your plant is rootbound also that could be part of the lock out.Ph is low also so i guess use less vinegar a transplant would do wonders. Your on the rite track get the ph under control and test your ppms

I was going to do a transplant but a 5 gallon root ball is pretty big and I can't put them in a bigger pot so I stopped. I'm going to flush one plant tonight. Try and get my runoff higher and the last gallon I'm going to have a small dose of cal-mag

I wish I had a tds meter but sadly I don't nor do I have the funds for one
