Hey guys need some help figuring out what may be wrong here.
So my plants have had dying leaves at the bottom and middle for most of their life, i've transplanted about 4 times but did a bad job on the timing and size of pots and also top dressing them and they been like this since they were in a 1gal container.
The pot they're in now is a 6gal pot and they grew pretty good the first few weeks but still had the same dying of leaves and since i'm getting close to flipping to flower i wanted to know if anybody had some advice on what to do.
Theyre in organic soil of around 40%cocofiber 30% pumice %30 compost/ewc. I usually wait until the pots seem dry to water but lately i've been trying to keep the soil moist but doesn't seem to be doing better.

I've giving them a couple of a&b boogie brew teas with has a lot of nutrients and some other nutrient&vitamin teas pretty irregular but never really saw any difference. Give the epsom salts in their water every two weeks or so. Just top dressed them all with 6 tablespoons of dr earth tomato and vegetable as well as 1 tbs of down to earth azomite about a week ago.
Pretty much all the plants look the same but the two biggest ones are the ones with most leaves dying off. Little are suffering the same but on a lot smaller scale. I know i have to remove a lot of bottom growth when flipping but i know it's bad to flip with dificiencies.

How often are you watering?

I'd like to see a picture or two of the whole plant.

I water them mostly every 3-4 days. Since it started to become to cold where i live i've noticed that they don't dry back as quick as they used to so they may be a bit overwatered. My dying leaf issue has been persistent though on all six of my plants. I'm thinking it's a nitrogen issue but not completely sure since i have given them around 5 nutrient teas in the last two months with no real dicernable difference. Will get more pictures when lights are on. The pictures i posted are of all 6 different plants.

It might help to know the temperature and humidity. Humidity increases when the temperature decreases.

There could be a nutrient problem, though. It does look like there could be nitrogen and maybe phosphorous deficiencies.

at 1st glance, they look like they're not very vigorous, could be many dif

causes. another thing is how thick you let them get. they need air circulation

throughout the canopy to aid in transpiration and photosynthesis and to

prevent mold and bug issues. also if you don't remove the dead and rotten

leaves it's a recipe for disaster - bugs, mold, diseases etc. that being said,

the 1st thing i'd [strongly] recommend is to remove some or all of that swarf

from from the insides of the plants. (i'd wait and see if others concur

b4 doing anything that drastic tho). also as @LoveGrowingIt stated, we need way

more pertinent info to be able to better help you out. happy growing

brother, hope you get things sorted out.... -peace-

It’s an interesting soil mix to call organic, 60% of the ingredients are inert (coco and pumice) more info about would be helpful.

During lights off lately they average around 58F & 75% rh
During lights on they average around 62F & 67% humidity
It's been pretty cold lately. Humidity has been pretty high all run though.

i just found this online:

".For cannabis, a commonly recommended ratio of earthworm castings (EWCs) in your soil mix is 10-20% by volume. This means you can mix 10-20% earthworm castings with 80-90% of your regular soil or growing medium1. This ratio provides a nutrient-rich base and improves soil structure and water retention" source was THCFARMER..

is it possible for too much ecw's be causing water retention/poor oxygen?

i've never been a dirt farmer - anybody?

I failed to mention that i also ammended the soil before using it. I used the recipe that the weed in a pot channel on youtube made for a organic soil mix. I also made a super soil mix that i put at the bottom of my pots when i transplanted to 6 gallons. Wasn't really a whole lot though, maybe like 1/5th of the pots size filled at the bottom with it.

60% rh is way too high when plants get that thick, imho, that's

why you have what look to me like rotting leaves ( i have old fading eyes tho)

and again, i've never grown in dirt, however; all plants need water, light,

nutes, oxygen and co2 to thrive. this is the same in all styles of growing

That makes more sense.

Yeah they do look to be petrifying and not all of them are bright yellow like i would expect from a nitrogen deficiency so i'm not sure why they're dying. You really think it could be the high rh?

honestly not sure, that's why i say try and get consensus

ps. i've also been on the side lines for 22yrs and am quite rusty & crusty, if you will 😉

great shite in here, still try'n get consensus tho, many symptoms can mimic ea other

I will look at that tomorrow when i can actually load a webpage in less than 5 minutes lul i have really bad service where my grow is at. And i appreciate all the advice either way, I was hoping to upload more pictures to show but i will have wait until tomorrow. Sucks because i know it's going to be a while for it to resolve if i do find a solution because of how long it takes for dry amendments to take effect in soil. Lul and i was really hoping to flip into flower this week but i guess i'll have to wait. :.(

I've been growing for 5 years and growing organic in Build-A-Soil for my third grow so I'm not a wizard but I can offer an opinion and you are asking for them.

Looking at your pics I think your garden looks righteous. Canopy filling the space. Yahoo! Trunk looks thick like shes been doing some serious vegging. It looks like your getting good results from your lighting and environment.

In this pic it looks like the pot is too small to contain an expanding root ball for a plant that big IMHO. The leaves look a little light green. I imagine roots are quickly filling up (within a couple weeks of transplant) and pulling all the Nutes out of a pot that size and they have 2 or 3 months to go in flower. Once the plant feels the squeeze on nutes or water she's gonna sacrifice leaves to save the flowers.


I think your suffering from your own success. You started with a puppy and now you have a Great Dane to take care of. Can't really see but it looks like the plants are maybe 3 feet tall and 3 feet wide. They'll probably grow another 2 feet in stretch. I think they're just demanding more food and water than those pots can provide. I think you should transplant into 15 gallon pots now before you flip, or at least do one of them to see if it helps for future grows. Examine the roots to see if they are circling or bunching up in the newest transplant soil when you have it out of the pot.

The dynamics of watering change as plants get big. A schedule that worked early won't later. Perhaps someone with experience growing in coco can offer you tips on watering big plants in coco during flower if your unsure. I've read that you need to water often and thoroughly. And you might check with the company that made the soil mix. They might have guides for their products on their web site. My advice on watering is, when you decide to water your plants, take an hour to water slowly so all the soil is wet to the bottom of the pot. Don't just moisten the top. Also, I've seen a few grow diary's on here from coco users who use drip watering systems to keep up with the needs of their plants.

I've never grown in this medium so take the above with a grain of salt. I'm offering my take on it but I'm just looking at pictures and trying to relate. I wish you success.
