2 plants, same variables, 1 great, 1 dying

So i have a photo Jack Herer thats doing great, and a Special kush #1, that looks like its dying.

Both plants have the same variables, soil, lighting, water, nutes, etc..i cant think of anything thats different besides genetics. Any idea why 1 plant is doing great and the other is dying?

Also are the leaves on the jack turning yellow a product of maturing during flowering or something different? My mind is escaping me right now, im pretty sure its just natural.

Pictures going to be posted in about 10 minutes, but until then, and without them, can anyone think of a reason why this is happening?



So besides the fact that maybe both are lacking from watering, try and look past that, as thats not a big deal. I just watered as i took the picture.

Newb question but do both the plants have proper drainage and ventilation? The droopy one looks like a lack of co2 imo. Or maybe even it requires a higher or lower temp? it just doesn't look like normal nute deficiency.

They are in the same area, both seem to be draining well. Ventilation is only when i open the closet door, not much else. It could be co2 i have no clue about co2.

Check the soil ph

The first plant looks like it has a small case of too much nutes (browining on the edges), the second one can be from all kinds of things. I have two kinds of C99 growing- one will take much more nitrogen than the other.

I think all this maybe is 1 plant is more resilient to high levels of nutes lower your feed, and get rid of them dead leafs

I usually grow different varieties at the same time and it has happened to me before where one plant was loving the high nutes and the other was all deformed from nitrogen toxicity. They never come back from it when in flower. Or many times i get a shitty pheno that will not do right no matter what I do compared to the others in the same grow with the same everything. it is hard to be sure.

What kind of growing medium are you using?

Overwatering maybe not enough ventilation could have root rot lack of oxygen id just transplant it make sure not to over water and make sure you have plenty of ventilation.

fox farm ocean forest

plants are still stalled in flowering completely. not growing at all, this has never happened to me before. i might just cut my loses and just completely redo my entire grow. Different pots, soil, lights, everything. And disinfect the area

Are the plants locked away without any ventilation most of the day?

Id say change soil and get it into bigger pot and happy frog soil. You could try and give the plant diamond nector it helps the plant take in vitamins when it has a hard time getting its nutes. Dont take my word for it though try and get info from the internet or any cannabis club or someone who knows more about that. Ive never heard of that happening sorry for your missfortune.

You could be overwatering maybe makes sure the soil is dry about an inch down before watering and only water till it comes out the bottom then stop. Could be not enough water maybe too. I dunno im just guessing.

Is it worth repotting this far into flowering? I guess it couldn't hurt as its not growing right now. It looks like it has some nute burn, but could that totally stop a plant from flowering? Could it be a co2

Yeah for the most part, I had a fan in there but I take it out at night when I sleep and use it on me. could that completely stop a plant from flowering? Its never happened before. I have quite a few grows under my belt and never had this happen before.

No but if you have nute burn then that means your over fertilizing it are you following the regimen on the container? If you over fertilized and you are getting deficiencies yes it could stop the plant from growing because it probably has nutrient lockout in that case change soil like I said and just give it water for a bit or try diamond nector itll help but probably changing soil would be best bet if theres still time.

Could even be possible grow room too hot n moldy as well could be alot of factors unfortunately ADMITTINGLY I dont have a straight answer sorry man..

If you change soil make sure you keep an eye on your ph levels too I think eventually the ph adjusters in ocean forrest and happy frog eventually wear out that could be another reason which also could mean your water is too high in alkalinity or two low and acidic..

You should check your ph level in your faucet water just for good measure and check run off from plants as well.

Different plants and strains react differently. The reason I asked is because the plant looks "Stressed" rather than burned or under fed, it seems to be something to do with the environment, if it were feed / nutrient based you would see yellowing and deficiencies well before what you see now, plus the entire plant seems to be effected. It really does look like either its been suffocated or extremely over heated, excess moisture in the grow area is a possibility as well. I would think some fresh water with a light feed and fresh air could revive that plant, is there no chance of keeping it in a darkened bedroom with an open window during dark period for a few days, or getting some kind of fresh air to them?
