I have a plant in DWC. It's at 2 weeks in flower. The larger leaves are cupping and drying up. It looks like Nitrogen toxicity, but hasn't been getting much N in flower other than from the Calcium. I'm not using the Nitrogen "Grow" nutrient.

Nutrients are GH Flora trio, Botanicares Calmag, GH Armor Si (silica), fulvic acid, a touch of Thrive Alive.

Could the Calmag really cause a Nitrogen issue? I understand Grow More makes a Nitrogen free nutrient.

Sorry I cant.
By "natural" light I mean turn off grow lights for a moment and use your camera flash. It will help us see details not otherwise seen in your current lighting. More details will get your problem solved sooner.

This is an overall view of the plant20200131_084447.jpg20200118_200410.jpg

Its approx. 4 feet wide. The strain is DNAs Strawberry Banana. It was a clone from this plant.20200131_084435.jpg
As I said, it looks like a Nitro issue, but it's not getting a lot of Nitro

I know what you meant. The issues are pretty obvious in any light.

Did your solution of Si get mixed in wrong?Youll have a brown color,that or root rot or.....you have a bug problem i see specs on your leaves.Or your mix is just out of wack.

Silica was added first, a d set over night in the system. No brown color, no root rot, I had little flying bugs, looked like white flies but much smaller. I sprayed them with neem and that was that.

It really looks like Nitrogen toxicity, but there hasn't been a lot of N. Just using the Calmag for it now. The mix is pretty tame really. PPMs are just above 1000. I didnt say anything about it earlier, but I'm using a PK booster from Grow More called Hula Boom, at 50% dosage

Because there couldn't possibly be an underlying issue that's easily missed..
Just trying to cover all the bases.
I know dude, and I'm sorry if I'm coming off like a dick, I just wanted to bounce this thing off a couple guys to see if I'm missing something. I completely understand what you're saying

I looked at the pot a little closer but found nothing flying. 20200131_144313.jpg

I reached around to the other side and didnt feel any root balls that could have gone bad. I dont think it's a bug thing in here.

Well a simple flush for 24 hrs and reset at a lower ppm should clear things up. DWC is pretty forgiving as you know. Stick with basic nutes until it clears.

You're so polite! What are you doing here on Roll it Up? I'm not talking about any of the folks helping me now of course, but, there are some rude mother fuckers on this forum haha. I dont think I've ever gotten a thank you before

Yeah, that was next. I *think* it's something easy, like a Nitro issue, I just wanted to kick it around with some of Roll It Up's finest. Thanks all
