HELP! Whiteish yellow leaves

[JLid905]

Hey everybody, new here and first time posting. I’m growing outdoors, 2 clones I got from a friend. They’re a month old now. On the one plant I noticed the leaves are a whitish yellow but only one one branch and not the rest. I’ve given them 1 feeding of fish emulsion 5-1-1 when I transplanted to bigger pot and was going to give them another one tonight. We’ve gotten a good amount of rain lately so I haven’t had to water. But it’s been hot this week and today so I’ll should be able to water again either tonight or tomorrow morning. I’m not too worried since it’s only on one branch and the rest looks good to me. I’ve looked around trying to diagnose it myself and I’ve seen a few things but figured I’d post as well. Any help would be much appreciated. Thanks

Hey JLid905 - I looked at your plant for a while - it looks very good lots of very promising growth about to happen.

I looked at Ed Rosenthal's book -:because it is starting at a lower section means it could be Leaf Septoria or yellow leaf spot. normally only happens outdoors. It is a fungus, not deadly but could hurt your yield.
Ed says for prevention one could use neem oil, copper, potassium bicarbonate, compost tea used as a spray. Stuff like that.

But that's just my opinion.

Here's another opinion of mine - if it was my plant and only happening on that one branch - scissor time - snip it off. Just have a good long look at the rest of the plant to make sure it isn't starting elsewhere.

Other opinions are bound to appear and you should read them all before making a decision.

Unless I saw it somewhere else on the plant I'd remove that one stem and keep an eye out. All the newer growth looks great right now. So as stated above. Just keep an eye on it.

It is so white that it looks like an absence of chlorophyll in that specific leaf.

Thanks for the reply’s. I gave it the day to see if it changed for better or worse and when I got home last night it looked like the green was coming back in the new growth on that branch. I’ll give it another day to see how it does and if it doesn’t look like it’s getting better I’ll just cut it off. Thanks again
