Currently growing 8 auto’s and four of them either have Deficiencies or toxicity’s. I’ve linked some pics. I’m growing in miracle grow with gaia green dry amendments. Ph’ing my water to 6.5-6.8.
rh is 50%~ temps are 24C~ and the four that have issues are in their first week of flower. I’d like to solve any issues asap so I can still get a somewhat decent yield. Any help is appreciated.

Look like nuke burn. What is your PPM? I would flush it then just use PH water and see if it corrected.
there is a bit of nute burn and maybe also potassium deficiency . i dont think its a good thing to flush an organic grow . but im no expert . search for potassium def online
Yea I was also thinking burn, don’t have a ppm meter unfortunately.. :(
Sounds good, thank you! Hard to find info though because everyone is using bottled nutrients :(
yes i know what you mean i feel the same . i guess you should stick with the feeding schedule of your nutes but a bit less i guess . on the stage that you are, you also have the tool of foliar spraying. you can cover a lot of problems by feeding through the leafs . are you topdressing ? whats your schedule? for me a good quality soil ph meter has helped me a lot
Yea I already just top dressed and I’m thinking I used too many slow time released nutes considering I’m using a soil that already has nutrients in it. But yea I also have a good ph meter. Just trying to figure out if if’s burn or a potassium deficiency asap.. my lights were also a bit close so I put them back to the recommended height.
Here’s some pictures with normal light!
Looks a lot like potassium deficiency. But light burn has similar symptoms. What grow light are you using and what is the light distance from the top of the plants? More info on potassium deficiency: https://www.mrgrowit.com/post/potassium-deficiency-in-cannabis-plants
Two vivosun 300w’s, they stretched into the light past the recommended for a few days but I put them back to the recommended height! I’m gonna try my best to fix the potassium deficiency if that’s it asap.
Also, I bought these auto seeds that are struggling from a very sketchy new breeder at a dispensary so I’m also thinking very poor genetics is a possibility because I’ve seen others with issues. Although my other four auto’s are doing well.
