Coco and overwatering

Sorry guys was at work and this thread exploded. Thanks for the feedback. I have a recently calibrated ph pen and I am watering at 5.8-6.0 and my ec I for the babies was 550 or .5 and for the big girls they are at same ph but ec is 900 or .9

The main reason I think this is not nute burn is the yellowing is not localized to the tips. The browing is around the entire edge of the leave I cut off some earlier or I would show it.

Last grow I watered 3 times a day. Regardless of the number of times I water I always water tell runoff to better stabilize ec. Just really scratching my head on this one.
Your massively underfeeding. Increase your ec to 1.7 and get run off every day. It's a simple formula that works for every plant I have.... 9 new phenos... all stable and healthy.

People post that link coz it all works well.

Alright thanks for the tip... yea I have not increased ec yet because until two days ago I thought this was a nute issue then I figured it was overwatering bit now I have finally like 90 percent positive its due to a nasty infestation of root aphids...

Started digging through top layer of coco and saw tons of little root aphids... this has to be why my big girls are so stunted and the seedlings are turning yellow and wilting

I think you can over water seedlings, the 1st time I seen run off with the current was 2 weeks after sprouting, it didn't have a high ec the plants too small to evaporate enough water to raise the ec.
Imo the plants in the pics are too far on to over do it with frequency.

Pour some 1.0 nutrient through the coco and read the ec of the run off.

What's the run off ec?

I water my coco according to the weight of the pot. I've learned what "saturated" feels like, and you can easily tell when it's dry, you go to lift it & it's so light you can tell it's thirsty. After a hearty watering with runoff, often times I'll skip a day of watering on my small plants in the 2x2. My flowering plants get watered once a day no matter what. I've switched from doing runoff with every watering, to doing it every other watering; the watering in between is just to keep the coco wet.

I'll dig through my favorites to find the articles but I was reading about frequent fertigation and the bemifits of it. It all made perfect sense that you eater tell runoff in airy coco and it never gets too saturated to drown the plant. I had HUGE success with it my first run through feeding 3 times a day with runoff. My runoff ec was always pretty close to feeding due to how often I was feeding. Girls did great and had huge yields.

This time it's all diff... it has to be the root aphids because they were not there last grow. That's the only difference. Pics attached are from frequent fertigation on last grow

So setups with Bluemats need runoff? If you set them to get runoff you would overwater your plants. Mold would form. Problems would arise.
No you don't need runoff in coco. I use blumats with coco and go an entire grow without any runoff. Plants stay healthy until the end without any salt buildup. There are people quoting that coco for cannabis website that don't realize that nothing on there is 100%. Some of it is just plain wrong just as is much of what's on the internet regarding growing cannabis.

Yes! That's the website. We'll in any case I didn't figure it was wrong because I got amazing results for my first and second coco grow.

Going to try killing aphids with captain jacks bug dead spinosad

Can someone explain what bluemats are? Not sure we have them/it/whatever here

What are you trying to demonstrate? That its packed down?
That the root system suffered greatly. Normally I have to put some muscle behind tearing apart the coco. When it was chronically overwatered it pretty much fell apart.

Here’s a healthy root system in basically the same sized pot. Just watered correctly. This plant is still in early veg, so it’s far from maxing out.
