I was thinking about iron deficiency cause the yellowing is between veins and in new leaves

Whats your light/fans distance

what nutes?

and what are you trying to accomplish with those small buckets barely filled up with river rocks?

 

[shortarker]

Nutes are local made, buying US brands is not worth it here.

River rocks are just for plant support, works great

Whats your light/fans distance

Around 15-20 inches

How do you have 25 hours in a day, when the rest of us only have 24, lol?

Sulfur and or iron or both. Not a mag issue

Because of the moon they predict that 200 million years in the future days will be 25 hours long. lol 1.4 billion years ago days were 18 hours long they say....

Your reply is not useful, if you are bored go to 4chan, you think you are funny due to a mistake.

just curious. and kinda wondering what's gonna happen when the roots grow above the river rocks. i'd guess serious root root.

your nutes suck if you get a Iron deficiency. just a FYI.

pH is what you should look at first...most plants deficient in either Sulfur or Iron are deficient because of a pH issue or too much of something else locking out the element/s in question. If you're feeding anything worthwhile your nutrients should have enough micros in it to satisfy any need from the plant, aside from perhaps Ca or Mg (which cannabis have more of an affinity for) Good luck friend.

I changed the water two days and it is recovering. Same nutes..
