Help: leaf tips yellowing

[Haze21]

First time grower. Plants are one month old growing in coco. The Bottom leaves tips on one plant started to yellow and has slowly been yellowing the margins drying out and dying. and now the second set of leaves are yellowing.
Feeding it fox farms organic nutrients. Only one plant has this problem so far.

Hi. Find yourself a chart of Marijuana plant deficiencies. Also its hard to see the issue with the blurple lights

Try this one:

Looks to me that you’re probably splashing it when your feeding.

Thanks Bobulak. I have that chart. It’s hard to figure out which one. I’m leaning towards Potassium, Zinc or Nitrogen. I’ve attached better pictures.

trim off any leaves that are touching or close to touching the soil. They look pretty close to me. Close enough to cause problems like you're seeing.

Thanks. Doing that now.

The bottom leaves are suspiciously close to the coco but if it moved up to the second set of leaves I'm going to have to say it looks like potassium deficiency. How often are you watering and at what ph? Always with nutes right?

I am watering every 2-3 day. Water PH about
6-6.5. And yes using nutes.

 

[AdaminCO]

Drop your pH to 5.8-6.0 and water every day once or more at 1/4 strength nutes.
Coco requires you to go in a bit lower, and water more often than soil. You can’t let it dry out.

I still thinks it’s because it’s getting splash from the feeding.

• ph adjust

Follow the left side of the chart. You’re missing the drift through a lot of micros and your K.

I haven't had that drastic of tip-yellowing but in my experience in soil is because of the ph. then the ph could be locking out some of the nutes listed above by others.
edit: Adam one-upped me. I'm saving that incredibly useful chart.

Follow the left side of the chart.

So if you grow in coco you should follow hydroponic ph levels?

Yes.

Great! Thank you all for the help.
