the 2 completely yellow ones have been clipped off. they where in ffof transplanted to ffof. the 100% yellow ones where the very bottom leaves.
no additives/nutes have been added.
I have been having the same issue with my two plants. The very bottom "true leaves" on each of my plants have turned yellow got crispy and are beginning to fall off. I am using Canna Coco with nutes. From what I have read and posted so far I have come to the conclusion that it has nothing to do with calcium...Tap water has plenty of it. RO water= Reverse Osmosis Water and need to have calcium added to it by buying Calmag. So if you are not using RO water dont worry about Calcium deficiencies.
Anyway to the problem, the yellowing in the leaves. Well I am still trying to figure out what that is from. So far I have reduced the nutes 1ml from each type and made a new batch of water. Then I had read that Chlorine is tap water so a person who uses Tap water would have to let the water sit for 24 hour to evaporate some of the Chlorine. So I went to the store and bought a 5 gallon jug and filled it up with tap water which I let sit out for 24 hours and TONIGHT I WILL BE MAKING A NEW BATCH OF NUTES (LOWER NUTES) AND TAP WATER THAT HAS SAT OUT FOR 24HR.
The yellowing on the leaves has gotten worse on 1 plant and better on the other. I am doing two different stains so that might have to do with something. Hopefully this new batch of water will show results. Ill try to post pics tonight.
Just recently found a good form about nutes that could help check it out its in my journal.
