Tell us a little bit more about your grow. What soil are you using? How long have they been growing? What light are you using and what's the light schedule? What's your water source?

I don't have the answer but you'll definitely need to add more information for an accurate diagnosis.

Magnesium deficiency. What medium? You can foliar spray cal mag.

680 watt led only at 40%, fox farm ocean, 24 hr light, water source from tap, 48 days old, still in veg.

They look overwatered to me. How far is the light what temps are the room and what humidity I would bump the light up to like 50 percent for a day and see how the respond but temps and humidity info would help

How much and how often do you water?

There should be a template for these kind of post.


Definitely include the watering habits though, I also remember reading if the environment has low humidity it will may cause the plants to transpire at a higher rate that is faster than it can uptake nutes which will cause problems.

This is your problem right here. They need food.

Make some compost tea. Crank that light up, too.

I would agree, they need to be fed. Generally if I see discoloration on the lower leaves I think deficiency. If the discoloration is on the top I think over feeding. In this case it's time to give them some food. I'd give them 900-1000 ppm of whatever fertilizer you are running for the next couple waterings. As another member mentioned, make sure it has a good amout of Magnesium in it or add some cal mag or epsom salt.

As far as the light goes, I agree they are going to need more intense light once the nutrient deficiency is fixed. For now I'd keep the light intensity at 40%. Maybe give them 4-6 hours of dark. I find to get the added growth possible with continuous light you need to have everything pretty dialed in. I find 18/6 or 20/4 to be more a better, more forgiving option in general.
