Leaf Diagnosis

[conesy]

As title says I’ve got an issue with some leafs on one particular plant, I’ve looked around the net and can’t find a definitive answer as to what it could be. Medium is coco and nutrients is canna coco a and b plant is outdoor.

Hey mate are you able to give bit more info....how often are you watering, coco is a hydroponic medium, needs solution everyday to feed, pull fresh oxygen through the roots and stop the coco drying out, which will cause nutrient salts to build up.... are you only using the a+b, no rhizotonic or cannazyme? whats ph going in compared to ph runoff and the ec/ppms also going in and runoff??

Definitely looks like a nutrient problem or perhaps ph lockout....

Can't really see properly, looks to me like some sort of insect attack, are those white spots eggs?

The insects maybe under the soil causing nute deficiencies, the colour change at the start of leaves,

Take a pic of whole plant there may be other symptoms which can help with diagnosis

If you have coco outside be sure it never dries out, as dr said the may lead to nute lockouts, causing deficiency, I don't think it's nute burn

As it’s only my second grow I think I’ve made a mistake with not letting my feeding run off fuk all which would explain the salt build up and the leaves looking crispy, my ph when going in is 5.8 to 6, the run off never tested and I’ve never done anything with Ec which now I’m thinking I should run down to shop n grab an ec metre

If u want to grow using nutrient mixtures u can't be without 1

Make up heaps of ph water and flush all the salts out. And get that EC meter.

Yer I’ve made a couple hundred litres up for the next couple days to flush them, mind you it’s only 1 plant that has the issue out of 15 but none the less I’m sure the others will catch up if I don’t do anything about it, also can someone explain how ec works and why it’s so important? Or if someone can direct me to a URL link. Thanks. Much appreciated for the help guys. Merry Xmas and happy growing

I sorta didn’t realise that having them all in 52l pots would use up soo much nutrients each week. Probably gonna cost me a grand just for this grow in nutrients . I always just kinda thought giving them a couple or a few litres per plant each day would be enough even if there was no run off. Ohh how naive and dumb that was haha.

Haha yeah mate especially when its hot like this, i have mine in 30L pots and im feeding them 6ish litres a day per plant at the moment, you want at least 20% runoff with coco mate[emoji16] and seen as your using canna , go to growguide.info , thats cannas online nutrient calculator, has helped me heaps over the years [emoji6]

Is it too late to put them in soil ?

 

Or perhaps set up a recirc system, not sure if that works with Coco.

 

I’m watering my 50l pots with around 25l per day before I see any run off at the moment. That’s in soil...
