leaves have strange spots and yellowing

What seems to be the problem with this plant. It is an ak-48 and the only one out of 6 that is showing this problem. I grow in soil with 6.2 ph and use fox farm nutes. using t-5 and cfl for vegging. They are 3 weeks old. any ideas will be helpfiul.

Thanks for any help!

Here is a photo, I forgot to attach it in original post.

How are the roots? Maybe time to transplant...

You may want to try a good flushing and give her 1/2 nutrients to start or maybe even try a BC product with lower sodium.
You may also want to introduce an LED that gives you a good red, blue spectrum. If you need help with LED's you can contact me for more info.

Good luck!

thanks for the replies but I do not think transplanting is the answer, the leaves have looked this way since week one. I have been giving proper nutes, the way I always have and never had this before. It looks to be some kind of nute defienciecy but the photos I have of nute problems look nothing like this problem.

Fill out the copy-and-paste troubleshooting form and paste it in this thread. Without all the necessary info, we're just going to be guessing. The more info, the better. :thumbsup:

I am having the same problem still. I've taken everything i possibly can into account and the only conclusion that i've been able to come to is that it must have something to do with my tap water. Even though i've adjusted the ph accordingly.. alas my problem persists. I've noticed my roots are growing at an insanely fast rate however. I transplanted into 3 gallon pots not but 1 week ago and my girls are already showing roots through the bottom drainage holes.. Anyways sorry for clouding your thread with my unecessary problems. I wish you the best with your grow and hope you get to the root of that problem! Happy growin man. Definately fill out the troubleshooting form. :hippy:

Also i'm using ocean forest. I'm a stranger to this organic soil so im not used to these new problems. Are you using this also?

Hi will somebody help me?
My first indoor plant :) i has problem with yellow spots.
My plants have 4 weeks old from 2 weeks yellow spots start showing. In first 2 weeks the temp. was from 82 to 91 degree. Now when light is on is 84 & humidity 45% and when it off is 65 degree & 75%.The air movements are fine. Is the Temp to hight? What nutrients will be the best for them.

First off, the plant is VERY likely root bound,... So re-pot that sucker.

Second issue is 70-80 is closer to optimal temps during lights on. 91 is a little to hot.

Third,.. Although such high humidity during dark hours will likely slow any chance of mites. Anything over 50% risks molds, fungus and gnats. So keep it around 40-50%.

Lastly,.. It kinda looks to me like nute burn. Those lower leaves are where high nutrients will collect and burn them.

So,.. Let it dry out, then re pot. Make sure your lights out humidity stays under 50%. Don't use nutes until it recovers. Then use nutes very sparingly.

First pic is a 4 week old minutes after re pot, before recovery.

Second is the same plant a couple days later.

how i can drop temps?

Vancefish i have to re-pot to bigger pot?

Aye, re pot that sucker. Once dry enough to pull the pot, do it! :thumbsup: You'll likely find roots clinging to ALL the edges of the ball. Once in the new pot, with extra grow space. It'll just take a couple days to recover and look great again.

Technically high temps just cause the plant to evaporate more water through the leaves. Thus making you water more often. However if it gets to hot it can hurt the plants. Most people just use a fan to pull in cool air.

I think your biggest issues are the tiny pot, and the excess humidity at night (Thus risking molds and such).

The yellow crispy leaves at the bottom are likely the nute burn. Just reduce nutes and water with straight water a couple times before using ANY nutes.
