Hi, I'm having some issues here. I never had that bad of issues and have been growing for almost 10 years. I'm battling and its getting worst. I have been using this exact method and never had much issues before. Only 2 plants are bad affected and they are affected differently, also 2 different strains.

.Mid week 5 of flower.

Temps/rh: 78 F° / 55%rh

.Grow method: Organic living soil.

.Nutrients: Slow release organic amendments feeding it once a month. Fed 2 weeks ago. Feed brewing tea every other water feed. (worm casting,molasses,liquid fish, bokashi,kelp meal).

Ph: Not adjusting ph, the microbes in organic living soil are supose to do the job. Using declorinated water at 7.2 going in. (tap)

Ppm: not testing ppm. Organic feed once a month.

Light: Led qb boards at 800 ppfd to the top heads.


1st picture: top leaves are affected. yellowing and rusting starting from the tips and progressing to the middle. Leaves curling downward. Also I have circle rust spots. I suspect nuts deficiency but I just fed 2 weeks ago !

2nd picture: Top leaves affected. The side edges and the tips are rusting , curling upward this time. I suspect nuts burn.

Only 2 plants out of 4 are affected, the 2 other ones look good. I dont know how to approach this. Cant flush organics and I dont want to feed amendments that late in flower.

Thank you for taking the time to read my tread 🙏

How long have they been in there current pot? Did you make sure you transplant before flower if they are photos?
Have you tested the soil ph? Should be 6.2-6.8 anything higher or lower will lock it out.

Clones in party cups and I transplant once in a 4gal pot. I normally dont transplant after that, never had issues, I will definitly check my runoff next time tho, never had issues with ph in living soil before

Do not water with run off with dry ammendments. Take a slurry test. Get some soil and put it in water and test ph. You don’t want run off because it pushes out the microbes and nutes. But how long have they been in the current pot.

Also you don’t need the tea unless it is showing deficiencies. Your medium using dry ammendments should have everything you need. Could also be why it’s showing some burn.

So I normally feed teas every other feeding ( once a week) in flower and it explode them real good. I tried to feed them teas every feeding see if I can get more out of it .. This happened instantly .. I believe I loc

Since transplant from solo cup ( 1st week of veg ). I believe I have a K lockout because of too much molasses. I never transplanted twice and never had problems I believe this is not the issue !

I think molasses is the cause or you just need potassium. Molasses seems to lock out K and I never touch it anymore because it always seemed to do this with my grows.
So i tought about it all night and yes I believe I locked out K with too much molasses. I normally feed teas every other feeding in flower. I wanted to experience every feed from week 3 and they did not appreciate I think. I just gave them a good straight water with 20% run off. I believe in teas tho. I see a huge difference when I feed teas, literraly in 24h00 period huge growth, so I will keep using teas. I will definitly cut molasses in half tho. I use molasses to feed the microbes in the tea , not to feed the plant. I wonder if I could use something else to feed the microbes in the tea.

Either cut the molasses when brewing the tea or brew longer to allow more consumption before adding to soil. But realistically you should probably limit tea waterings to every third watering similar to liquid fertilization scheduals. Regardless of the inputs, too much ends up asking too much of the soil and too much of the plant.

Yeap thanks for the advices. Will give a second water feed in 3 days and then will cut molasses in half + brew an extra 12h 🙏 That locked pretty good. Low yield incoming 😬

Think of it this way. Molasses is about 6% Potassium give or take (I don't know the N or the P but assuming 0 for this) every watering you are giving the plant 0-0-6 unless I am mistaken. Cannabis doesn't need all that much K.
I know lots of people are into teas and I'm not trying to sway anyone. It really depends on your soil. If your soil isn't enough, you need teas. Build the soil rich and you can skip that step. Soil microbes want a certain ratio to build. Carbon....Nitrogen......Phos.....and a lesser extent Sulfur. Build a soil rich in carbon and you bypass the need for sugars at least IMO. I think that ratio is amazing and wish more were into learning about it. Build a soil that feeds microbes in a ratio of 100 : 10 : 10 : 1 CNPS and see what happens. Magic.
