Yellowing and Burn

[greenhousefaith]

Having some extreme grow problems. Noob grower I spared no expense and run top line equipment, not seeing the results
using technaflower nutes according to instructions, trying to control PH of city water

 

[ChasingGreen]

What kind of soil is it? How old is the plant? If you're following the bottle exactly, you might be over providing the ferts. I'd do some plain water for a couple cycles then cut back to half strength and see what happens.

I see a lot of deficiencies. N, P, K, Ca. I guess those nutes are too weak.

My guess and I'm no master, but I've read quite a bit of things about cannabis deficiency. Looks like you got brown spots on leaves before they turn yellow. That could be magnesium or calcium deficiency. Without magnesium and calcium the plant can't make chlorophyll ( Magnesium is the central element in chlorophyll.) , which will lead to yellowing, which can appear as a nitrogen deficiency.

Use your magiCal, calmag or calimagic etc.. Maybe foliar spray some Epsom salt.

Thanks for the feedback. A full comeback was acheived by connecting an air intake. I figured that the outtake would cause fresh air to come in from vents on sides but I guese it needed that intake to flourish

 

[macky1708]

got damn give that thing some nutrients go organic its easier

 

[Big-Narstie]

So adding an inlet solved the plants issues alone?? Did u have the flaps open or closed on the tent?

 

[greenhousefaith]

Once an air intake was added plants seem to make a complete turn around. flaps were open

are you phing your water? ..

 

[bigdad41296]

Damm all that from stale air? Had to be more to the problem

 

[Farmer B]

I would never guessed air. Look like it was growing in plain water/no nutes.

 

[iTarzan]

I am not falling for the stale air theory.

 

[exploziv]

Stale air means lack of CO2 means reduced photosyntesys. So it is possible.
From what I can see in the pics, soil looks way too moist, dunno if they were taken after watering or maybe the op keeps them too moist and that will hurt the plants cause roots won't be happy if they can't breathe.

Looks like you have many more problems than just air/ventillation issues. Got some kind of nutrient lockout going on also. Maybe a soil/water PH problem. Check the PH of your runoff water. I would switch to RO water and use 10-15 drops of CalMag per gallon of water. Also I would switch to TLO growing and stop using those nutrients/not needed in TLO growing style. You can have the best equipment money can buy, but if the soil/water is bad you will fail. True Living Organics is the easiest way to grow. Even if you do not want to mix and cook your own soil. There are companies that sell the pre-mixed/pre-cooked soil. Also the buds are so much better than sythetic/chemical grown or even liquid organics grown buds.
