Northern Lights (MSNL) First Grow

First attempt at testing soil ph, but I have been testing and adjusting nutrient solution every watering. My Digital ph meter was reading this at a 7, this is more 6ish with the ph chemical kit. This is my nutrient solution, am I too acidic?

The ph strips def read more accurately.
I’d try to get it to that 6.5 #.

But full disclosure, I haven’t ph’d in years. Been a long time.

That’s what I was thinking, going to up it next watering.

Is closer to 6.5 just general throughout growth?

I was reading that some growers raise ph in flowering.

I’ll have to toss the baton off on that. I have no earthly idea. I really just always tried to keep what I put in the soil balanced. But that was only when I smelled over treated water coming out of my facets. So as far as runoff, I never really did that. I’m curious as well here.

Pots are drying out daily now I think partly due to the increased airflow and because they are packing on bud weight.

I raised the nutrient ph, the new color seemed to be between a 6.5 and 7. I might have raised it a bit too much, will get it dialed in better for tomorrow’s watering.

I do think one plant has septoria, taking no chances I defoliated 3 leaves.



The gray middle with ring around it is what makes me think septoria.

What are the drawbacks of using hydrogen peroxide soil for the one plant with flare ups?

Yeah, it’s very light spotting whatever it is.

I know I can’t keep defoliating over 1 or 2 spots. I’m just being extremely careful with it, I would rather sacrifice one plant over the whole garden.

@GNick55 , here is a plant with a flare up. I’m convinced it’s septoria. I’m going to cut back infected leaves and mist soil with diluted hydrogen peroxide in attempt to kill any septoria that the surface soil is holding in this pot.


A couple other plants have like 1 or 2 spots at most, this is the problem child…patient 0.

2 days in to week 4 of flowering

Hopefully this week some weight will be added to these dwarf plant popcorn buds.

Shoot Dang, I should have checked my phone when I was watering.

Already treated P0 with 1ml of hydrogen peroxide in a cup of water misted on top soil. Defoliated infected leaves and added a black tourmaline for some hippie healing lol.

She looks thin, but ok.

Garden is starting to crash a little bit but I have hope for it.

Bottom leaves are yellowing and brown splotches.

Pots are dry every morning.

I cut out most nitrogen and feeding ferts every other day.

It seemed to get worse yesterday when it was a non feed day.








I’m wondering if I’m overwatering even though no water comes through bottom and soil is rock hard.

I just don’t know if I need to flush or if the plants are actually craving nutrients?

With small pot sizes that dry out daily I feel like I need to fert water every day like you would in hydro.

I’m struggling to control mg lockout in the garden right now.

It’s strange because the shorter bushy dark green phenotype is showing barely any lock out but the other type is suffering.

The beastie bloomz has high K levels that I believe triggered/accelerated the lock out.

Flushing and giving base nutes for a few days then switching to Cha Ching.

Buds are starting to fill in and get frosty, just need to control the lock out and keep the garden alive for a few more weeks.
