Have been scouring these forums for a little while, first time posting.
I have just started my first grow. First seedling sprouted 15 days ago and these guys have been growing like crazy. Im the past 6 days they have grown about 5 or 6 times their size. See below
I was thinking it may have been just the start of light burn. This plant was sitting in the most intense part of the light. I am using 2 x 315W CMH 4200k lights in half of my tent which is an area of 5x5.
I am feeding Canna Cocoa A and B and also a root promoter called Drive, once a day at the moment. Sometimes i wait up to 36 hours to feed because the cocoa is still wet.
Ph of nutrient water is between 5.8 and 6. Just wanted to see what you guys thought.
Not sure what pH for Coco @PreyBird1 or @devjyarn will know but they’d the range for soiless mix like pro mix. U may have some lock out,I’d flush with proper pH water and a weak nutrient solution.is that plant by the fan wind burn can do that too.or possibly too much light but I’m leaning towards pH issues
Thanks for your fast reply. The guys at the store said I didnt need cal mag because Canna Cocoa has added cal mag already.
This plant was actually sitting right next to the 250mm intake fan. I have since moved it. It wasnt in the direct line of the wind but leaves were rustling slightly.
What’s the ppm of the nutrients your feeding?
The ph in coco is same as hydro aim for 5.8.
You’ll need to add calmag too. Especially if your coco wasn’t prebuffed…
I would dilute the nutrients some. Try around 350~ 400.
What is your base ppm water reading. Is it tap, rain, well or reverse osmosis. If you’re starting with a high ppm water theres not much room for the nutrients while keeping your ppm in check…
I don’t often go over 600 ppm In veg. If i am its not till late veg when I’m almost ready to flip. I Would dilute the mix and see how they go. Having another look. They look fairly young. Maybe even go as low as 250~300ppm.
What part of Aus are you from?
I’m in W.A…
Yeah got me mate coming tomorrow to give me a hand. Will be putting them into their final pots. 25L fabric pots hopefully they are big enough. Wasn’t expecting them to grow this fast, they outgrew these 200mm pots in a few days. They looked so small in them 6 days ago.
I think they are looking awsome for their age. Definitely doing something right.
Just remember if you push too much you’ll just stall the girls, they won’t like it.
It takes a bit, but eventually you’ll be able to read them and get to know what they like and how much you can push.
Good luck mate…
Im not pushing them on purpose. I am just following instructions from the Canna website on nutrients and added the Drive root promoter which was recommended by the guy at the store.
I am trying to learn as much as I can. I will flush them tomorrow before transplant and then run lower ppm for a week or 2 and grab some calmag see how they go after that.
Thanks for all your help mate.
I always shoot for 5.8 max ever 6.0 but i have found that the 3 brands of coco i have tested have been naturally buffering the ph so havent had to mess with it as much anymore.
Just a wild shot here and looking at my grow bible. It could be a mobile deficiency like magnesium or potassium. To treat it quickly you could do a small spray solution of epsom salts and foliar spray. Looking good though.
