    Continuous yellowing from the bottom. Please help!

    I'm listening and i appreciate your help. I cut the nutes down during a week and the yellowing kept going. Then people told me that there was not enough nutes on here... Thank you for the link. The thing is that it's hard to know what to do when you get advices in opposite directions.

    Continuous yellowing from the bottom. Please help!

    Anybody? The plants are still growing well. I changed the watering to 15min ON 15min OFF. I think the roots might have gotten a little too dry between watering.

    Continuous yellowing from the bottom. Please help!

    It seems to be getting worst and spreading to the latest fan leaves. The leaves on the branches are fine. Even at the bottom. Even if i start over i don't even know what to do differently. I've been told to feed them less, then to feed them more. i have no idea what to do next.

    Continuous yellowing from the bottom. Please help!

    How much the EC should drop every day or so in a healthy system? Is it that noticeable? Running the EC much lower at 0.8 kind of made it worst. Could it be calmag deficiency from using RO water? Thank you for your help.

    Continuous yellowing from the bottom. Please help!

    Here are some more pics from today. Any help will be much appreciated. It seems like a cal/mag deficiency with the browning/yellowing edge of old leaves and little rusty color spots on the leaves.

    Continuous yellowing from the bottom. Please help!

    I redid the res yesterday and i put exactly 30ml-60ml-90ml in 50L of water. And 30ml of mag. The yellowing keep going. Isn't there a way to tell what kind of deficiency it is? Could it be that i'm watering too much or not enough? It's around 29 to 30C degrees in the room and the humidity is...

    I didn't see any white mold on them. Is it normal that i don't see the EC dropping after a few days even at 0.8 EC? The yellowing is still going on. I increase the EC to 1.1 then 1.3 today.

    Continuous yellowing from the bottom. Please help!

    GHE advises EC about 1.5 to 2.2 during growth and flowering. Also i just realised that i didn't shake the bottles of nutes. It's the 5l ones maybe it's causing the problem. Maybe i should raise the EC higher than 0.8. Unless you really need to reduce it with aeroponic due to the constant...

    Continuous yellowing from the bottom. Please help!

    I never used straight RO water. The RO water is EC 0.1 or less. Right now it's at 0.8 EC using GHE flora series. I put all the details on the first post. When i top off with pure water it's just to bring back the EC down as it raises 0.1 after 2 days of evaporation and plants drinking. Do you...

    Continuous yellowing from the bottom. Please help!

    It was at 2.5 3 weeks ago. I slowly dropped it down to 1.1. And now people suggested to drop it to 0.8 EC. What is the good EC? I was hopping to see some EC drop in the res at some point to get a reference to increase or lower the EC but the EC never drops. When i top up the res it goes back to...

    Continuous yellowing from the bottom. Please help!

    I've dropped the EC down to 0.8 and the Ph is already at 5.9. They are growing well at the top but i still feel that the yellow will keep progressing to the further up. Also the middle leaves have some brown rusty spot showing as you can see on the pics above.
