Yellow lower leaves, nitrogen?

[blondie]

I’m thinking this is lack of N. Two lower leaves only. Not a huge deal but I want to get ahead of it. Anyone agree nitrogen deficiency?

 

[Douglas.Curtis]

Nitrogen or overwatering are two main leaf yellowing forces, I believe.

ph lock out can be a factor but normally you would see other signs as well wilting/curling etc

Pictures would definitely help narrow it down

I plead the stoner defense. I forgot to attach my image.. whups.

Here is....

well, imho looks like a little over watering and a little deficient early to mid stages, what does the rest of the plant look like?

 

[blondie]

Rest of the plant looks great. Nothing else happening except a few lower leaves yellow. Plant on the right in the attached.

I don't think that's nitrogen. They generally just turn pale yellow and dry up. That is a mobile nutrient deficiency I would say if it's a lower leaf. Just like I had on my current grow on one plant. Mg probably maybe K.

 

[Maple_Flail]

ya rest of the plant looks pretty good to be a N deficiency at all.


organics or salts?

Old age or they are pot bound.

Post a photo showing the whole plant for the best answer. It's almost impossible to know anything by looking at just one leaf.

Blondie, those plants look really lovely and you're doing a great job. The leaves are heat-stressing a little in the photo. Protect the container from direct sun contact to help keep the plant roots more relaxed. Also since they are outside you could put a thin layer of mulch on top of the container to help keep the roots cooler and more relaxed. Next month is the start of flowering time and keeping the plant cool and healthy now will help greatly in the end.

Here's my two girls about at the end of it all giving up their N from the lower leaves. 8 and 9 weeks GDP.

More images. It has in fact been very hot. I thought since lower leaves it may be low nitrogen very early stage. My tomato plant first image which is next to the ka5h has some similar type of yellowing.

Thanks for comments everyone. Much appreciation.

I've been giving my larger plants plenty of water.

Thought today I'd give them some Nitrogen.

Human Urine diluted 1:1.

 

[Douglas.Curtis]

Standard dilution for plants is 1:8, might want to dilute that a bit more for safety, unless this is a regular thing for ya and it works fine.

 

[Maple_Flail]

yup my tomatoes are doing that right now,

I'd trim up the middle foliage to allow a bit better air flow

and 1:1, 0.o hope they are used to that!

My tomatoes are slowly loosing the lower leaves. Not unusual but this year I'm adding calcium, magnesium and potassium as top dress. Hopefully it slows it down. I always thought it was fungus, maybe it is. Usually by the end of the season it's consumed the whole plant but the new growth.

if it is nitrogen you also notice it from how the petiole easily detaches from the stem or branch... other deficiencies such as magnesium or potassium show much more resistance to splitting

 

[blondie]

I tried to pull the affected leaves and they didn’t want to come off easily. This is great to know. I added some Epsom and another Nute. I’m pretty sure the one remaining yellow leaf turned green after this. Any rate, no more yellow. Thanks all.

Blondie I told you your plants are heat stressing. The yellow leaves are caused by heat stress, try mulching your plants when they are in the Sun with hay. My outdoor plants are needing water every day, even with mulch, though the ground seems moist.
