All of my seeds have germinated which I'm excited about but I have concerns about what I think may be nitrogen burn because the plants go through the same thing Everytime they will germinate sprout and grow for about 3 weeks then it looks like someone took a blow torch to the leaves they start out looking burned then turn yellow not to long after the plant is dead. I have tested the soil pH and it comes out at a solid 7.0 which as far as I know isn't to acidic so I'm just totally confused, I'm pretty desperate for some help here guys I've already gone through a pack of seeds the last thing I want is to loose all of these plants so any advice would be awesome

@smartin3722, hey if that is the ph you are running it looks way too low unless it is just the lights? It looks orange. You want yellow or a slight green. Any orange is too low. Yours looks well below 5 from the picture. If you look at week 4 of my wild west diary the yellow that shade is right in 6 compared to a test pen. Also it looks like your dwc seedling root is sitting in water? It is best to start dwc seedlings in a starter cube and transfer them to the system after you get a healthy taproot out of the bottom of the cube.

@smartin3722,your always gonna want to over complicate the begging but you can't no nutes for most growing mediums right off the bat .soil wait three weeks and so on man ..to save them now I'd say a lot less is more over watering is a killer everytime the roots can't breath and the light you have is 75 watt LED it pulls less in true watts from the wall you will need better light for better buds..I really wish you the best and hope you can turn the girls around man ..

I've got a few different grow mediums going on I've got a promix from a greenhouse that's full of perlite and peat moss I've taken the ph of the soil and it comes out at 7.0. I also have a deep water culture with the addition of an air pump for more oxygen to the roots I have an Early Miss Autoflower in there and 5 Sour Girl in the promix I'm just taking some picture to attach

How did you germinate the seeds? You should wait until they've sprouted before giving them to much strong light. Are you using soil and hydro? I'm confused by the pics.... Must keep the humidity quite high as they are still developing roots and can only use leaves to absorb moisture. Soil must be fairly dry, not soaked. If using hydro, you need to measure your ppm and pH levels all the time.

Just keep them fed at 75 PPM daily for a few days then slowly ramp up the nutes and they will be fine. You need a more powerful grow light for Veg, go on Alibaba and buy a Kingbright 240 watt 3000K separate heatsink QB. Also buy a bag of Mega Crop fertilizer it is specially formulated for Coco Coir.

Hey somethings ive noticed in the growing community, and something alot of us growers do. And thats overlook some of the problems that arent like a posterboard deficiency or toxicity. Hows your chlorine levels and your bromine and that stuff. That got alot of my dwc in the first month when i first tried it out. And the temp of the water is important when measuring. And chlorosis and plant illnesses happen alot to. You might want to look a little in that area online and do some research. I hope i can help ya out.
