Name that deficiency...please?

[Stoney75]

EDIT: Thanx for the help... S75

Yup, I'm brand new, and yup, I'm still screwing up.

OK, plants are in 3 parts - Pro mix premium (blue bag), 1 part mushroom compost, 1 part perlite, 2 TBSP / gal of dolomite lime, 1 TBSP / gal blood meal.

The two big ones had a feeding of PBP 10 ml / gal + few drops of Superthrive.
The smaller ones (not pictured) 5 ml / gal + the Superthrive.

You can see the yellow tips in the first pic.





They've also been foliar feed a light mix of Diamond Nectar and water.
All nutes and water is PH'ed to 6.0.

Here is a close up of the deficiency.



Thanx for any help or feedback...I'm hoping to get my first crop.

Edit: Plants are in a temp controlled wardrobe, - 1 deg. ambient, humidity 53%, lots of air movement / ventilation. They are under a 400 watt, hurricane glass, cooltube.

2 tablespoons lime per gallon of mix is alot especially considering promix is already limed and perlite has a high ph already.

How to test soil ph: After watering/ferting till runoff, wait 30 minutes. Apply a small amount of distilled water to the pot surface till 1 or 2 ounces of runoff occurs. Catch this on a saucer. Test this ph. If after watering/ferting and waiting 30 minutes you can tilt the pot and get some liquid out, you can test that instead.

OK, so what's a better mix for the lime next time....1 or 1 1/2 TBSP / gal. I'm planning to run the same soil for a while. Seems to work pretty well. Also, did I use too much blood meal? Some leaves are looking dark green. Should I drop it to 3/4 TBSP / gal next time?

Thanx for the reply though.

IMHO this doesn't look like a Mg deficiency being as there is no leaf curl. Those yellow tips and your statement about the dark green leaves makes me think too much food.

Ideally, you should test different lime rates with your soil mix. Using 3 seperate containers, add 1, 2, and 3 teaspoons lime per gallon of mix. Wet very well. Wait a week. Mix 1/4 cup soil mix with 1/4 cup distilled water. Stir. Wait 30 minutes. Test this slurry ph. Pick the best lime rate. Be sure to mix the lime well with the soil...it needs to be uniform.

I don't recommend blood meal because its ammonia or urea nitrogen and not nitrate nitrogen. Outdoors in soil some would be converted by microorganisms to nitrate nitrogen. This does not really happen in potting soil. Ammonia/urea nitrogen is toxic in large amounts because it cannot be stored if in excess. Feeding in your water allows you precise control of what the plants are being given and can be increased or decreased or leached out if needed.

Is there any way to improve the situation?

I read in another thread that blood meal cannot be flushed out.
How bad do ya think it is?
And yeah, there is a bit of downward/clawish leaf curl on some of the tips.
No toooooo bad....but its there.

Should I just ride it out?
I've had to change soils/transplant a couple of times already.

I tried using this mix from Organics for Beginners.
--------------------------------------------------------------------------
Or, if you use Pro Mix or Sunshine Mix...
LC's Soiless Mix #2:
6 parts Pro Mix BX or HP / Sunshine Mix (any flavor from #1 up)
2 parts perlite
2 parts earthworm castings
Powdered dolomite lime @ 2 tablespoons per gallon or 1 cup per cubic foot of the soiless mix.
If you use a 3 qt. saucepan as “parts” in the amounts given above, it equals about 1 cu. ft. of soiless mix and you can just dump in a cup of powdered dolomite lime.
---------------------------------------------------------------------------
I couldn't find EWC, so I subbed in the mushroom compost.
I added the bloodmeal cause they were yellowing.
Now they are getting too green. LMAO.
Doh!

Blood meal is an excellent fertilizer for veg, both inside and outside. Been used for centuries. It's also slow release so it shouldn't be an issue. That downward claw can indicate to much Nitrogen. I think you'll be fine riding it out just don't feed her anymore for right now. The Pure Blend Pro plus the blood meal is a lot of Nitrogen.

Thanx bro. I was thinking / hoping the same thing.
I'll ease up on the nutes.

Other than that, they look ok?
I'm doing a bit of LST, trying to create some growth shoots.

I can't wait to flower em.
Speaking of which, should I repot for flower, with no bloodmeal then?

[pastor420]

Looks like you have a good start going on the LST. She is looking very lush.

When you repot for flowering don't add the blood meal as that is a veg nutrient. If you were going to add something it would be bone meal which is high in Potassium, though if you'll be using the PBP Bloom then you won't need to add anything.

Hehe...thanx....I love to tie a hot bitch up...or down.

Edit: OK...I'll drop the bloodmeal before flower....less dolomite lime?
1 1/2 TBSP / gal ?

I also have some unsulphered molassas (Grandma's)...and Awesome Blossoms.
When is the best time to use the molassas?
And it's 1 teaspoon / gal....right?

And yeah, I got the PBP for flower too.

just be carefull with advise my friend......it just could be your soil is a little 2 hot....and then adding nutes is not a good combination...What is the NPK ratio saying on the bag?

NPK of which?

The bloodmeal is 12-0-0
The PBP Veg 3-1.5-4
The lime 21.6% Cal, 10.0% Mag

My mix is soilless so no NPK....right?

[pastor420]

Core makes a good point. The Pro-Mix is pH adjusted already and then with the extra you added sure could make the pH soar.

Perlite is pH neutral

Pro-mix is always low pH. They do not add enough lime.

 

[Stoney75]

Hey inflorescence, thanx for chiming in.

So, you said the pro mix is low pH, so the 2 TBSP/gal of dolomite lime shouldn't be a huge issue?
OK, i just looked at the pro-mix and I don't see HP, BX, TBK, PGX...so I'm not sure which one I got. It's a blue bag, it has "water saving gel", and reads "Premuim Pro-Mix for Containers" near the top.

It's lights out now, but I could snap another pic today to get some more opinions.

They were looking decent last night.

Thanx again everyone.

Stoney, I've never added any Dolomite to my Pro-Mix (both plain and BX) and haven't had issues. I use it straight out of the bag and have had wonderful results.

And FWIW, I don't use RO water either. I guess I just break all the rules.

Lol...Im using half R/O water and half well (hard) water.
Then a little pH down to get it to 6.0.

But no dolomite?!?!?! LOL
I looked for that shit for like 3 months cause everyone here swears by it.
And I'm also using the PBP nutes, which are supposed to be a little light in Cal and Mag.

S75

 

[pastor420]

I looked for it about that long too initially. Been looking for it recently though because of what I've been reading around here. LOL Same thing with pH, never worried about it before and now I've been looking at these cheapy pH meters ?!?!

Anything that might be lacking in the mix in the way of Ca/Mg is supplied in the compost and manure teas I feed the girls with. Those store bought nutes are out of my budget range, so living in the country you do what the farmers around you do.

If your water is hard then that is basically "liquid dolomite" because the calcium and magnesium carbonates are what cause hard water and happens to be the same stuff as precipitated dolomite lime powder.

Guess your not breaking ALL the rules.

Didn't know that I was drinking lime water...LOL

Maybe that's why I got hard burn all the time
