Plants look like azz... help!!

Temps: 72 to 75F
Humidity : 40 to 50 %
Lights 400w cob led 30" above canopy.
70% ffof 30% perlite
Nutes 400 to 500 ppm 9-3-6 plus 70 to100 ppm or so cal mag.


Struggling to figure out what I'm doing wrong. Had same soil same conditions last grow and hadn't almost no yellowing sagging leaves. Just replanted from 1 gallon to 3 gallon buy plants were looking ragged before the transplant. Have other looking like crap too.

RO water with nutes ph'd to 6.0 to 6.3. Runoff tests 6.0 to 6.3. Seems like a lockout issue. But ph seems ok for soil.

Watering when container drys out and is light.

Root mass looked like this, not exact plant but representative.



Here are the two plants but have others that look like shit.



Any ideas?

Seems to look like a cal mag issue, but have been adding cal mag and ph seems ok.

Also, runoff ppms are 1000-1300, However as an experiment I mixed up a gallon of 70% FFOF 30% perlite mix and ran RO water through it and that tested at 1000ppm after straining through a coffee filter.

they need nitrogen for sure...what are the temps in the grow area?

72F to 75F.

Also, from chart looks uptake for N is between 5.5 and 7.5 so should be ok. Wondering if I should bump up the nutes next watering. Also figured new soil from the 1 to 3 gallon transplant would supply some nutrients if needed.

nitrogen is mobile, looks immobile to me, if nutrient issue.

Try and keep humidity closer to 60-65 and see if that helps. Sometimes over transpiration can cause curling like that.

Your hunch about transplant shock is probably a factor too.

You shouldn’t have to use any nutrients with Ocean Forest so early.
It is a relatively hot mix out of the bag.

yeah, been the case in my last grow... waited a good couple weeks into veg before any feeding and all was green. Ii that case went from solo to 5 gallon though.

last indoor grow was right at 50% didnt have any issues. My buddy grows in AZ and its like 10% and he hasnt had a huge issue.

IMHO.
That's a lot of ppms man. Especially soil.
I'm at 900 ATM in coir. Plants are triple the size, and 3rd week of bloom, to put it in perspective.
900 is pushing the limit for me too. My nutrient is a 5.3.9.

So do I flush for a while or dial back ppms to say 200 to 300?
Didn't see tip burn so thought I was not over feeding.

I think a flush will do some good. I'd just be feeding water too. Until it improves.
I think it's touch and go too. Sorry.
Good luck. I hope they get better

Was that grow in ffof also? The thing about low humidity is that is causes increased transpiration, ie the plant takes up more water/solution through the roots. So it ends up getting more nutes than it can use.

Just my $0.02

Flush em and see how they do. Keep ppm low. Best wishes.

Same as last time.. 70% ffof 30% perlite. Last grow was 50% humidity most of the grow due to low humidity in winter. Here's a pic. Only diff is veg nutes. And added some silica this time around.

Nitrogen dude nitrogen. Perlite is inert it has no it has no NPK value. Its function is oxygenating the roots. If you add perlite match it with worm castings. EWC have nitrogen among other goodies. I have seen grows with 50/50 perlite and worm castings. Some girls can be nitrogen whores. Don't forget that.

IMHO. OP.
Your ppm is way too high for soil. I don't think I've ever grown in soil, with 1000ppm. I was a longtime organic outdoor grower, and was in the veggie garden since I was a Toddy. Before moving indoors.
Everything just happens so much slower in soil. It's the bacteria feeding on the nutrient that feed your plants. The soil is alive. 1000ppm is a lot for bacteria to handle. Especially without the presence of worms too.

In no way am I showing to show off. I just want to try and make a point. I run my flower nutrient 5.3.9, seedling to harvest. Very rarely do I ever need calmag. If I ever use it. It's only for a boost of nitrogen.

You'll notice 900ppm is even a little too much nitrogen for mine. I have a tiny bit of claw, here and there. My leaves are dark too. I'm in coir. It's fairly inert, and is almost lifeless too. I need to feed my plant rather than my soil, in hydro.
You always feed stronger in hydro.



IMHO. You're not deficient in anything

Are u running dyna gro?

I was doing 500 to 600 ppms.. run off was 1300 to 1400.
Then I tested virgin ffof 70/30 perlite soil and runoff with 0 ppm water and that in itself was 1000 ppms.

If the roots look like that pic just up pot in fresh ffof and water only for a bit.

Why use a hot soil and bottle feed?

I havnt used dyno grow before. Sorry.
I'm using a generic brand of nutrients. "Growlush" ab, flower, synthetic. I think Dutchmaster, makes it for them.
I'd recommend doing a soil sample myself. You can use a soil sample, with distilled water. You can find the ratio on google or wiki.
Reason being, runoff is inaccurate for soil. Because it's flushing nutrients, and solids too. Even if you filtered it. Which would affect your ppm reading, and more than likely read higher, than what the medium actually is.
I'd recommend getting a sample from the top, and bottom. Then compare the two.
I havnt used fox farms before either. They don't sell it over here.
But it really does sound rather high. Soil will hold back, more nutrient than coir too. Has less oxygen as well. Which makes over feeding worse.
TBH I think judging by ec will be more accurate for soil too.
We go by ec here. But measuring the electrical conductivity in soil, imho will give a better representation.
I'd recommend using organic nutrients too.
