Marijuana Plant Leaves Turning Wrinkly And Crinkly

Hello guys, I have been noticing an issue with my grow recently. I started growing this plant about a month and a half ago and it was growing beautifully, but then it started showing signs that something was not right with it. Some leaves have light yellow spots and the other leaves are turning wrinkly and they eventually turn crunchy and fall off. Even the new branches that are emerging have leaves that are doing the same .I have the plant supported by pencils because it keeps tipping over. I don't know what I did wrong, but I'm giving it sufficient water and nutrients. The lighting schedule I have it on right now is 18/6. I was using a blurple light before on one of my other plants, but the whole plant burned and died so I switched to white LED for this plant and it has grown pretty big. Can someone please tell me what's wrong with it? Thank you.

looks like you need a larger pot, it could be over feeding and or over watering, but you havent mentioned feeding it.
could be a problem with the roots, being in such a small pot, it needs more soil to support the plants growth.
is that tomatoe plant grow bag in the back i think, the yellow colour is the same as uk tomatoe grow bags,

I picked up a Rainbow belts from a store front a few months ago and it does this too. It grows healthy, I’ve kept it in big containers and it keeps loosing leaves in a crunchy fashion. I’ve tried everything. Not sure what the issue is but I’m probably going to toss it. Lol. What I’ve learned is if the plant doesn’t like your methods and style of growing move on to something else.

I am feeding it nutrients but I don't know how much to feed it and how many days apart. I'm just eyeballing it.

That is a miracle gro bag. It's soil.

ok, ive never grown in the stuff, but i believe it has food allready in it and you shouldent need to feed it for a while,
so as its been fed, you would do better to either start again with a new seed, or get a larger pot and replant it.
you should read the bag and see what it says about food in it.
mirical grow isnt the best to use, but its ok to start with, its hot, which means its not the best to start a seedling in, you use a general purpose potting compost to start the seed off, then move it to the mirical grow when its large enough.
try a larger pot and dont add any more food untill the lower leaves start to turn a pale green colour, then you start feeding it.
what food you giving it?

ok, i will most likely move it to a bigger pot. I'm using general hydroponics nutrients, nitrogen, calcium, potassium, phosphorus, calcium, magnesium, and sulfur all in one gallon of water. I put all the nutrients in one gallon of water and now I'm realizing that may be the issue. I think I'm not supposed to add all the nutrients together.

Just a guess here as I'm no pro, but I have a feeling you are cooking that thing. Your soil has nutrients in it. While people shit all over Miracle Gro, plenty of people have grown healthy plants in it. I would quit feeding it and just switch to straight water as needed. As far as it being weak and needing support, that's probably a feed issue as well as you need a fan on it. The breeze on a plant is like exercise for it and it helps them to build strong stems.

The plant looks like way too much N. Too much water, too.

Yeah I would say way over fed. The MG soil has slow release nutrients in it and then it’s being fed on top of that. Transplant it into a bigger pot and just water it when it needs it not when you think it needs it when the pot is light and the soil is dried out a bit. Looks like you have GH trio in the pic to so if your just eye balling how much to feed it more than likely it’s way to much.

Bigger pot for sure, water when thirsty (light).

I have a fan on it but I think I may be overfeeding it. I had grown a plant 2 years ago without nutrients and it was not potent at all. It smelled like grass and tasted like hay. People said I waited too long to harvest so I burned all the THC off and maybe that was the case. I just thought feeding the plant this time around would make it grow more potent. I guess I'll stop feeding it and try to flush the soil with pure water.

Thank you everyone for your help! I think you guys have helped me out a lot and gave me some good advice. I will stop feeding it and just use plain water. The question now is, will it flower potent?

Potency is going to be genetics. You obviously need to grow and maintain a healthy plant, but that potency is up to the plant. The grass and hay issue is from not drying and curing correctly.

I doubt you will get anything out of it. That thing aint getting enough light. Way to tall and lanky.
