Having some problems

To start I just want to say thanks in advance. I have 4 plants in a 4x4 tent with a 400hps.
I'm in dwc with clay pebbles in 5 gallon buckets. I use general hydroponics flora nova. And calmag. I think I'm having a nitrogen and phosphorus diffencacy.
It's about 4 gallons of water. I use a little less than the recommend strength for floranova and the full recommend for calmag. I think the first plant is nitrogen and the second plant is phosphorus. . The other two plants are fine.
Flora nova is 4-8-7 and the calmag is 2-0-0
My ph is about 5.9-6.0. Ppm is about 600. Week two of bloom.
What do you guys think?

does your fert already have calcium and magnesium? if so, you probably don't need to add any more. could you be having a bug problem? that's kind of unusual damage and really doesn't look like a deficiency problem.

Pretty sure no bug problem. I think so but I use ro water

all you are showing that is not looking good is lower growth from lack of lights, nothing to worry about. The slight tip burn just means you have been riding the line of maximum fertilization, over fertilizating just a wee bit, she<s big and going to need more food as she is still stretching so I would say change nothing.

It's the cal mag your adding. 100%. I use floranova 1 part and been there but it's great stuff. Instead use maybe a 1/4 tsp gallon of Epsom salt per gallon, it's a small amount. Keep the ppm total to 700ish through out and you'll grow as good as any body here. Test cal mag and RO water only. It adds a lot of ppm by itself. Rid yourself of it. 4.5 cc bloom to 1 gallon RO will get you those numbers. Don't go switching ferts.

Btw I don't see what you're seeing in the pictures, they look pretty damn good to me

So you would say just stop using calmag and start using Epsom salt??

Absolutely

YUP!!

Dont over analyze things...thats when shit can really get skewed!

Thanks everyone for helping out just trying to get a run with no severe problems. Will be posting on the forum frequently.

dying from the bottom up usually means something is locked out, if your ph is high 7+ it will lock out the nitrogen which will then lock out you mag. its eather cal mag or nitrogen def.
