Typically a plant in hydro of this size it's more a root issue than nutes unless you're burning it. Are they growing well? Is your tank level too low/high? Until those roots can reach you want that root zone kinda misted but not saturated.

Looks like either a ph imbalance Or possible light bleaching. Plants can also be really finicky with nutes at such a young stage.

Fast yellowing in older and middle leaves, small buds.
Hi guys, I need your help on this one, this is a completely organic grow under a FC-6500 light which is 60cm at 100% power, it can't be light stress because the tops are fine.This yellowing happened fast in the span of 4 days.PH shouldn't be an issue since I calibrate regurarly.

How many days of flush until yellowing?
My first grow. I've been flushing my DWC Blue Dream for 4 days now and no sign at all of leaves turning yellow. Everything is still nice and green. Does it start from the bottom? How many days is normal?

Sources of Coco Coir and other supplies are drying up due to shutdown of shipping from Asia.
Already getting hard to find decent Coco for any normal price. Have 8 cu ft myself will be getting more if I can. This could be rough for coco growers. Ideas and any other items of concern? I am thinking LEDs 😳

Do I have a deficiency problem or am I ok? 3 lower leaves on both plants started with the tips browning but now the leaves are going yellow. None of the newer growth has been affected but the 3 leaves seem to be getting worse. See pics in week 4!

Another seedling grows nearby ?
Another seedling grows in my new cannabis's pot for a few days! My seedling is only a 1.5 week old and today I notice this! What the heck. I use the regular common soil 70% + 30% vermiculate. Could it be some seed in the soil? What should I do? All info in my diary for otherplant

Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy disk
Sudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Yellow spots on leaves
Am I correct in assuming that the spots on leaves were probably caused by ph fluctuation? If so, is there anything I can do besides flushing with proper ph water?

Leaves bright green
So I have ruled out the fact that this is not a ph problem, have been properly watering at a consistent ph of 6.5, tested the run off today and it's at a pH of 6.4, also there is purple stems and the main stock has purple running through it as well?!?! Is this lack of pk? ca/mg?

High nitrogen problem
One of my plants/pots seems to have too much nitrogen. I haven't top dressed or added anything besides microbial inoculants, agsil, homemade photoplus(pnsb), and aloe. What can I do to help reduce the nitrogen in the soil? I added extra mulch.
