Leaves are looking horrorable

[abadtrip]

Hi party people I have a real issue that I am not being able to work out I am thinking about scrapping this plant and starting again.
She is 23 days from seed a Hindu kush auto from South Oregon seeds.
I topped her in the second week she is growing strong I feel. but the leaves are turning a rusty color and dieing off. I have tried upping the nutes. Ph is right in the 6 range she is growing in dwc plenty of air. She is under a 300w viperspectra. I don't know what is wrong. Please help i was thinking bad genitics as it's a free bee and no info from them about the strain.

I had similar spotting on my first grow. How do the roots look? The first thing I would do is flush it if you are in hydro, and then give it low nutes for a little bit. See if that helps, and then work your way back to the strength you were using. Take my words with a grain of salt though, I'm only on my second grow

Ok I'll give it a shot try a flush I am just a a loss as to why every other plant I have grown has been fine not that I have grown alot just 5 different strains but this is a first for me

Could be a calcium deficiency. Do you use calmag?

Yep I do magical by technaflora I'll up it maybe she wants more

Do you check your pH about a couple hours after a res change? Mine always went up in hydro, so it was good to put it in a little lower than you wanted it.so maybe 5.6-5.7 and it would work it's way up to 6

I check it every day my water out the tap is 6 and a ppm of 5

PPM of 5? Lowest I have achieved is 170 PPM.

I live at the base of an uninhabited mountain my well is drilled into bedrock I am pulling nature's finest out the ground it tastes amazing.

So I looked back in the log and I am only running 2.5 ml of magical i gave her another 5 ml see if that helps

 

[Doubledealing72]

That could be the problem. Also seems to add up with the awesome water you're using. Gotta put a calmag supplement in water with a ppm that low...from what everyone seems to say online anyway

Does your pH stay stable at 6 or does it fluctuate up or down over a few days? My understanding is that you want to let it drift in between 5.5-6.5 in hydro. Mine naturally drifts down so I start around 6.3 and let it fall to 5.5 and then correct it back to 6.3.

When the plants get bigger and start really drinking the ph does go down but by the time it gets to 5.5 I need to top up the res with fresh water
