Any idea what is wrong with my plants?

[PK1]

i think he should flush it 2x the pot size.

 

[GNick55]

sounds like a flush is what to do, but you’ll lose your nutrients by washing them out, so you’ll have to probably start feeding them after.
you’ll have to get advice from someone else , i don’t know auto flowers, i don’t like flushing. i know you can’t be mucking about with them as time is limited as another member mentioned.
my way would be unconventional and i wouldn’t advice someone else to do the same..

 

[Mr.GreenthumbOG]

Plant looks much improved. No flush. Stay the course.

+1 the new growth looks great.

You really need to water to runoff. Unless you have a high quality soil ph pen. Either way I would wanna know runoff ph in your case.

I would with synthetics but with organics I kinda don't see the need.. maybe every few waterings to check ph if you are having issues. The reason I say that is keeping the soil in the optimal o2 and moisture zone. With synthetic we need to flush out some of the old to prevent a buildup at the cost of being over saturated and lower o2 for a while until the plants drink up some of the water. Its a trade off. If you can keep the soil between 30-60% then it has a much better air holding capacity and high o2 levels but with synthetics it usually creates issues with nutrient buildup so we water to runoff.

For ph I would probably just do a slurry sample using something like a large straw or something to get a core sample from top to bottom.

Just my reasoning and opinion.

Slurry sample would be smart. Blue lab soil Ph meter would be better.
Get the ph under control either way.

[Mr.GreenthumbOG]

Growing in a goddam bucket isn’t helping the drainage much.

100% and I agree about the bucket... I honestly can't say enough about the fabric pots.

i disagree. Watering to runoff helps clear the roots of waste and brings in more oxygen. Also helps clear out calcium from tap water.

and of course gives something to monitor for root pests and rot or disease.

and helps to know the pot is fully saturated.

I water to 20% runoff from the first watering even in ocean forest.

In peat yup... better drainage. But no need to remove organic nutes. You also are using synthetic nutrients so yeah I agree with ya there

 

[MIMedGrower]

comparing my and other plastic pot growers results i am going to suggest cloth pots do nothing beneficial for out plants and may cause more issues with uneven drying and watering through channels.

wouldnt matter if it was coco. You dont want buildup regardless of nutrient source.

absolutely +1

 

[Aqua Man]

I should say yes watering bring in o2 but when the media has less drainage like soil and isbsaturated its the gas exchange that suffers. So as that o2 is used up there is not much being replenished... it goes stagnant in a sense and can end up anaerobic... see varying degrees of this in the form of over watering.

Sure it does... only need to flush through if to much is added... not near as common with organics but yes possible... but thats just grower error.

runoff doesnt mean over watering. Need a bit of patience in potting soil but thats my favorite feature. I can equal yield with so much less water and nutes.

That’s the beautiful thing about growing. Grow in a hardware bucket. Traditional plastic pots. Whatever.
personally I use fabric. Almost Impossible to overwater. Can control airflow through the root zone better. Only negative is transplanting out of them.

bro-science answer. Nature waters with plenty of runoff to clean roots. ;-)

Mr. G

for me transplanting is the big negative.
