Hi, I need some help with my plants that are grown 100% organic. I using royal gold kings mix for soil in 7 gallon grow bags. The nutriments I use are Super Soil Organic Concentrate (https://www.amazon.com/dp/B07BDKTT7Q?ref=ppx_yo2ov_dt_b_fed_asin_title) and it worked great till about two weeks ago. Temp stays about 78 degrees and is an indoor grow in a 4x4 tent using spider farmer SF4000. I think it might be a nitrogen deficiency but that's what I read. This plant is a landrace strain of Jamaican and was hard to find. I don't want to lose it. Can somebody please show me how to get the leaves back to green,

led lights can be quite intense for a plant , and if its a bit too much the plant with lock out nitrogen first so you lose that healthy green , then it will lock out potassium (i think) and leave darker veins. have you got your light at 100% or closer than about 18 inches?
this magazine has an article about changing leaf colours page 22 ,

Light at 20 inches and at 80%. Thanks

That might be too intense. More distance and a lower percentage probably would help, if only to reduce the stress on the plants and let them recover.

I turned it to 65% and I have maxed my lights at 20 inches. I will have to rig something up to get it higher. Thanks for info

Every three days. Thanks

That's probably okay, but it doesn't mean the soil isn't too wet. When it's too wet, gas exchange for the roots is reduced. In particular, they need oxygen. Lacking that, a nutrient lockout can occur, thus the chlorosis of nearly the whole plant. You could try letting it dry to see if the color improves.

I will give it a shot. I lift bags to see if they need water is this alright?

Lack of vertical space is a common problem. I've grown plants up to the lights a few times. About 24 inches seems to work well, but even more is okay. I bit more power is needed when they're high, though.

That's what many growers recommend. A moisture meter probe can provide useful information, as well. Letting them dry to a slight wilt won't hurt them. They like it when the soil dries back.

The question is what caused the chlorosis. It could be wet soil. It could be too intense light. It could also be magnesium deficiency, but I doubt that because it has a different appearance. I'd tweak the light and the soil moisture and pay close attention to how the plant responds.

There's always the possibility that there could be more than one problem. For good growth, all the growth factors need to be balanced.

Thanks that seemed to take care of the yellowing problem.
