Maybe a nitrogen toxicity problem or deficiency

[harlem09]

So I'm a newbie to growing cannabis. This is my first plant and I don't know what's going on or how to fix this issue. Maybe a nitrogen toxicity problem or deficiency?

 

[Renfro]

Ok, what type of medium is it potted in?

What are you watering with? Tap water, RO water? PPM pH? Any feed?

 

[harlem09]

Watering with RO water, medium is foxfarm,fish bone meal,Rose and flower mix,azomite, and compost. I did a compost tea for her which looks like it started new growth.

 

[harlem09]

Since young seedling I've been using liquid seaweed and urb in a spray bottle. Just till recently almost a week ago I did the compost tea. I just order some cal-mag so I might try a little of that to see if it'll help.Any suggestions on fixing her up!

 

[harlem09]

My runoff water pH 7.2. The water I was giving her with the seaweed and urb was anywhere from pH to 6.9,6.5 and just recently 6.1.

You have a lot going on in your mix. Your pH seems a bit high; this is where I'd start. Good luck.

 

[harlem09]

Forgot to mention the strain is northern lights. Should I flush her? If so how? Worrying a flush might make the plant stress and make matters worse.

 

[CannaCountry]

No, don't flush it. The starting point is this: pH You need to get a handle on it before going too far.

 

[harlem09]

I've done the flush yet! I'm waiting till the medium dry a bit. When you say get a hold of the PH you mean from the roots or my watering? I'm going to start watering with 6.2 pH I just purchased Nectar for the gods Hades down. I was using general hydroponics pH up & down. The bottom leafs feels dry and paper like.the two really dark ones don't fine as dry! I'm keeping the temps at 74 degrees sometimes it fluctuate 74-78 lights on and 69-70 lights off. And humidity at 66-68 lights on and 60-63 lights off. I have the Spider farmer SF-2000. I also have 4 more young seedling also that's stretching. So my new growth looking ok she's become bush . I bought some Epsom salt I hear its good for plants in general not sure how to use this yet. So I'm I dealing with a toxicity or deficiency?

 

[harlem09]

So any help or suggestions?

TBH with all that nutritional content it's just gonna have to run it's course.

 

[harlem09]

So now the new growth is starting a little dark green as well. And help in getting better?

 

[harlem09]

I'm thinking it's a magnesium toxicity. I have no idea what I'm doing.... I pH her water at 6.4 today with half a teaspoon of Epsom salt in plain water! I'll give her some compost tea in two days or so. Please help!

Bro you have a toxicity which means excess so why do you keep feeding it more lol

So what should I do? And what type of toxicity is it magnesium toxicity?

 

[harlem09]

I was think a flush? So I can take it out from the roots.It's affecting the new growth.

Nitrogen toxicity, everything you've added to the soil so far you should be good to water only for a good while

Should I flush her?

 

[harlem09]

Should I flush her?

The reason I ask is because it's affecting the new leafs.

Flushing should be a last resort if your having serious issues, your plants look healthy just overfed, you could water to a bit more runoff then you normally would but no dont flush IMO
