5 weeks old - one plant showing leaf damage

[Jestocost]

Pics are of a white widow. 5 weeks old, under LEDs. No issues until last week.


Other plant - same age, same environment - a NL, is thriving.




I have an idea this is something simple.


Nutes are Roots Organic Buddha Grow at 1/2 strength. 1 gallon smart pots in Roots Organic soil.


Thank you guys for your time and thoughts.

Looks like the beginning of a potassium deficiency

On the one hand it looks like magnesium deficiency/lockout at the beginning of flowering. pH needs to be a little higher for Mg and NPK absorption.

Also, airflow may be an issue with the plants being so tightly packed. I can't quite tell, however there should be no carpets on the floor, or wood.

However when there are a lot of nutrient issues all at once, it could be a nutrient lockout, because too many/the wrong nutrients are not taken up from the medium. The way to know is to measure the EC/PPM and pH of the first runoff.

A while ago i had s problem similar to what you have...a small piece of plastic was in the soil and the roots were trying to brake down the pc of plastic....repotted with new soil with b 1 and it recovered.

You are burning the plants because the ppm is too high.

You are burning the plants because the ppm is too high.

So one plant can take it and the other is overfed?

Is white widow finicky? It's been needing help the whole time, where the other plant just chugs right along.

I will measure runoff PH. But I'm not feeding heavy or doing any crazy amendments.


Thank you guys.

Agreed .....overfed
