New Grower KVS shorty

[trouzzer]

Feel free to take a look at the spotted leaf and give an opinion of what is going on. It seems to have started from the bottom and has worked up on the larger leaves. I thought it was some sort of leaf spot fungus.

This little LST'd KVS girl (out of 4 had 3 males) is on day 41 from sprouting and lives outdoors. She survived a worm that snacked on some leaves and part of the stem(this actually prevented new leaves on about 2 nodes from growing), and grasshopper that was 3 inches long ate almost 2 fan leaves.

Anyways she showed sex at 17 days, and is flowering pretty good right now. she is just short and ugly but smells like lemon head candy.

I am feeding her with bubbled fish fert 5-1-1 and started to give a small amount of unsulphered molasses this last week.

Can't say that I've ever seen anything like that before. I'm going to see if I can get someone else to take a look.

Any chance you splashed some nutrient solution on them when you were feeding?

I feed and water on the soil. This one does get rain water whenever it rains here. I have noticed that some of my other landscape trees have similar spots. Also another male I have is showing these spots.

I will try to get a picture of a younger leaf that is showing the spots

Look on the underside of the leaves and see if there are any insects or eggs.

I took a couple pics. Maybe it spread from my other trees or light burn from dew on the leaves in the morning. Does not seem to be affecting new growth.

What about septoria leaf spot? Ever heard of it? I saw this on a couple other boards. My Area is hot humid so maybe this is it.

I think you may be correct. I did a little quick research and it does look like septoria. If so, you'll need to treat them with a proper fungicide.

No more spreading so maybe that is what it was. I sprayed some Greencure on it once each week for the past two weeks. no spots on the new leaves or smaller leaves. On day 48 today. Pretty small but I think I like this for my location. I will have a couple of seeds from this go around for spring.

It will be interesting to see how this little one bulks up. she is pretty frosty all ready and from what I have seen on all of the other KVS they have went 70 days plus.

So with autoflowers do you always have the chance for a runt just due to genetics?

 

[Muddy]

Yes, autos are still relatively new and not 100% stable, so there is often a variation in phenotypes. As breeding and developing continues that should be less of a problem. I fully expect in a few years that a lot of strains will be available in several different pheno.

day 53 not much longer on the little girl

Probably about 3 weeks, maybe 4. Not really seeing any yellowing of the fan leaves yet. I do see a cal/mag deficiency though. It's the brown spots on the leaves. If your pH is good I'd suggest feeding some cal/mag supplement or some epsom salts and molasses.
