weird early flower growth possible herms

[Nisor710]

I've had an issue with nanners in the top off the buds my last few harvests in the top of every nug. you have to break down the bud almost to see it in the finished bud. only thing I'm doing different is a different microbe (photoplus) and I'm using a humic fulvic mix at 80%recommended strength (Wallace organic wonder). And age-old kelp at 10ml per gallon (calls for 15ml per gallon)
I don't know that these are herms but the tops of my buds look like they are forming weird? Like there are no pistils on the tops of the flowers. This is how my other harvests went that had the top Nanners.

In coco perlite
I'm using cutting edge solution louder powder at 2.5~ e.c.
1ml agave nectar per gallon
photoplus 30ml per 5 gallon
age old liquid kelp 10ml per gallon
Wallace organic wonder humic/fulvic seaweed 1 tbs per 10 gallon
water goes through a big boy filter and sometimes ill also add calmag
PH- 5.8-6.2


I'm using hlg lights I'm wondering if it could be the light intensity? But tis also happening on all the lowers. I'm using two 350 diablos HLG 350 Diablo – Horticulture Lighting Group at 100% though I crept them to 100% after about a week. Ppfd is about 800-950 at canopy and they are hung at 22 inches.

i dont think its light leaks
im curious if it could be a lack of co2
possibly dry backs im in coco i dont let my plants get to the point of drooping but sometimes a pretty light pot?
Thank you for your time and help.

That looks like the leaves are light stressed, I raise the lights more.

the ppfd is within acceptable range, and i thought this might be the problem but its also happening on the lower bud sites as well.
also i don't have the ceiling height so i turned it down to 80%

here is a photo of the entire canopy i'm not seeing light stress can you explain to me what you are seeing.
photo is from before i turned the lights down
please and thank you

You should be watering/feeding at least daily and probably multiple times a day in coco to runoff. Your first pic looks like fresh growth......maybe a tad light stressed. Second pic looks fine too. When you say lowers look like this too are you talking about fresh buds still?
I don't grow in coco so others hopefully will chime in....but I know you don't let it dry back.

i grew commercially for 2 years we grew in coco perlite and would water once every 2 to 3 days never saw anything like this. even on plants i brought back from the brink of death that got missed on watering (we were hand watering 300 plant to a room and there were 8 rooms.)
when i say lowers i mean the lower bud sites on the plant.... the bottom of the canopy is doing this as well as in the bud sites farthest from the light.
there are no obvious nanners at this point, but the flowers are forming very weird as you can see in the picture and have no pistils on the tops of the flower sites, i believee my previous harvests did this and they all had a popped nanner or two in the top of the bud and some seeds

Damage or yellowing of the tops of the plants can point to a non-mobile nutrient lockout, which usually happens when the pH is too high.

In coco perlite
I'm using cutting edge solution louder powder at 2.5~ e.c.

2.5 EC is already too high.

1ml agave nectar per gallon
photoplus 30ml per 5 gallon
age old liquid kelp 10ml per gallon
Wallace organic wonder humic/fulvic seaweed 1 tbs per 10 gallon
water goes through a big boy filter and sometimes ill also add calmag
PH- 5.8-6.2

You should make your mix of nutrients, and then test the pH and EC over time - immediately, 1 hour later, 2 hours later, 6 hours later, 24 hours later.

I suspect that the pH is slowly increasing over time.

If you don't mind going synthetic, this is all you need:

Canna Coco A+B
Epsom Salt
Ph Down

Keep the pH of the nutrients at 6.0 throughout the grow.

Keep the EC at 1.0 through vegging, and raise it to 1.6 when flowering starts.

Use less light. The light is for living, the dark is for flowering.

that yellow is just bright green from new growth ph run off is fine.
i check my res ph before i water every water. (yes it is aerated) and only sits for 2 days max.
2.5 ec is what it comes out at after i add all my nutrients at recommended strength.
i usually have betwenn 15-30% runoff depending on my last run off e.c. and p.h.
as you can see from the attached photo there is no nutrient burn or ph issues.
my leaf tips aren't even slightly tinged.
the issue in my opinion is the "knots" on the tops of the flowers and no pistils which i believe are going to turn into nanners.
you want your ph to be within 5.5 to 6.5 but i tighten mine to 5.8-6.2 for ph change in the pot. the reason you want to change your ph throughout your grow (preferably from low to high) is that different nutrients uptake easier at different ph. nitrogen at lower P and K and higher.

First of all, great grow.

The thing is that coco coir isn't hydro or soil. It has a higher pH requirement. If you aim at 6.0, you can't go wrong, because that's also the pH of the coco coir itself.

The pH that is made available to the plant isn't only the pH of the nutrient solution. It is the buffering capacity of the medium, plus the pH and buffering capacity of the nutrient solution.

Coco coir buffers to 6.0 pH, and if the nutrient solution is also 6.0 pH, there are no pH swings.

You can't go wrong with that. If you use synthetics like Canna Coco A+B.

Which is all I know about, because I haven't grown in coco coir with other organics added.

My experience is with coco coir synthetics, completely organic supersoil and compost.

What I'm seeing in this photograph is plants that are basically healthty and aren't dying. They have some early issues. The purpling of the leaf stem in the center could be nitrogen or potassium issues. The thickness of the leaf could be magnesium. The wrinkling of the leaves could be zinc.

The coco coir is mixed with perlite. Perlite has a higher pH than coco coir, 7.0 vs 6.0.

I think the problem is mixing coco coir with organic nutrients and adding perlite for aeration.

In coco perlite
I'm using cutting edge solution louder powder at 2.5~ e.c.

Louder Powder is not specific for coco coir.

"The Mineral Family of fertilizers from Cutting Edge Solutions® are concentrated formulas for commercial farmers, suitable for root-feeding in all growing mediums."

1ml agave nectar per gallon

Agave nectar is a natural syrup. I'm sure in an of itself it will be good, however it needs to be fermented before it reaches plant roots.

photoplus 30ml per 5 gallon

Microbe Life Hydroponics' Organic Photo Plus seems to be some kind of microbial addition.

age old liquid kelp 10ml per gallon

Sea kelp is a great addition to compost or supersoil. It needs decomposing, and can contain extra sodium and chloride, which are also alkaline.

Wallace organic wonder humic/fulvic seaweed 1 tbs per 10 gallon

"5-2 Humic / Fulvic Acid + Seaweed Extract Wonder Blend Wallace Organic Wonder" which is more seaweed, again more potential for sodium and chloride, which are alkaline.

water goes through a big boy filter and sometimes ill also add calmag
PH- 5.8-6.2

If you'd added all this to compost, or composted it with supersoil, there wouldn't be a problem.

Organic nutrients are always contained in something else, and they need time, bacteria, sugar, temperature and moisture to decompose. It is not something you want to go on in your root zone.

I think the best thing is to switch to a synthetic nutrient like Canna Coco A+B, even with the perlite added.

I'd say: go all coco, or all organic whether that's supersoil or compost.

And also in future grows, if you go with coco, don't add perlite, just don't water as often. Coco coir aerates itself if it is allowed to dry a little. (Just water when the top of the soil is dry before the lights go up, whether that's twice a week or every day, depending on plant size, humidity, etc. And use 1/4 of the recommended strength, as drying concentrates the nutrients.)

i think it was the light intensity.
