Nutrient Deficiency or something else?
Canna96started grow question 5 years ago
Is this a nutrient deficiency in my auto? I'm Growing in Coco, feed 6X per day drain to waste, PH stays between 5.7 to 6.3. CalMag, then Maxi Bloom powder, then liquid Kool Bloom. I did cut back on the calmag at end of Veg. running a total EC of about 1400. Thanks for any help!🙏

We found that the Cal-Mag should remain in low doses through flower.
Dont need it during veg as the CocoTek has plenty (assume yours does as well) but as coco breaks down unbuffered cation sites are exposed and begin leaching CA in particular but also Mag as well. This is why a lot of people discourage us from reusing old coco, has to be washed and rebuffered.

Your ec should be around 1.6 now and you should keep your ph 6 to 6.5 in flower. When you give a break and run water through check your runoff ec and ph to make sure their not out of whack. If the ec is coming out over 2.2 you should run water to lower at the proper ph. Hope this helps. Cheers

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?9 months ago

Yellow leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.Week 2
