My plants are growing nubs

Hey there guys so ive been learnjng grow mmj with my dad but we have run into a problem that hes never seen and he's been growing for a long while.

Any ways we had a problem wirh spider mites, took care of them with azamax. Everything was growing awesome. Blue dream, shishka berry, rascal o.g. Girl scout, girl scout platinum, and a few others. But as of 2 weeks ago they stopped growing leaves and started growing nubs. The top just turn into a calus (it look like a thinker plant and mutated.) I used organic dirt and organic foxfarm nutes.

They were going fine and nothing changed except the bucket they were in

Any ideas of what could be going on?

Upload a picture so we can help you. I tried picturing it in my mind but I cant so we need a picture to further help you my friend. Oh and put down all the growing conditions for a more tuned in response.

So i had three pics but this is the only one that will load the other are doing this but they are way shorter and stout.. No joke . And they look worse amd have bigger calus/nubs

Disregard, we posted at the same time, lol. I have no idea what is going on in that pic. Looks unhealthy to me tho, hehe.

Also im using a 400 watt and florecent over my clones in the same room. Stay a stead 70 and they are all in veg. Im not sure about humidity though

they look poisoned or over nuted..

So flush with normal water you think?

The top leafs look like my friends pug's face.

Looks like lacking micronurtients.

Like which micronutrients?

I would flush asap. I dont think Ive had a whole plant do that to me before, maybe a few leaves before I notice and flush out the poison. How long have they been like that?

Well my humidity was at 30% when that little cold snap hit my part of washington they just started doing that a week or two around the same time. We have a humidifier now and it stays about 50% after the adjustment we made. And we are hoping that changes things. Also my shishka and blue dream are wilty stiff, and some curl up on all new growth areas on the plant

And I know i didnt poison them. I measure and only give it every 3-4 waterings. I prefer normal water,the nutes just kick up bud size a little and add more flavor to the smoke

Zinc, Iron would be my guess.

Measure and give WHAT?
What is your PH?
What are you calling 'normal' water?

I measure the nutes. Its well water that tests at a 6.0

I would make sure your water reading is accurate. It looks like the ph level of the soil is making it difficult for the plant to absorb the proper amount of nutrients.


Its a boron deficiency. You have to flush your plants with clean water ph 6.5

You haven't used any herbicides/pesticdes in the growroom or carried them in from outdoors?

Have seen these nubs before. too much nutes. flush and flush and flush. Then do not add ferts until it is well on its way again. if you do, it will return and die. Go very easy when the time comes. It has excess in soil but also excess in its roots/cells. Flushing will not reverse it out.

You can over fert it even if you read low nutes in your bucket, if the water evaporates off or plant transpires a lot nutes will rise.
