Growing Tomatoes

Yellowing Leafs, any suggestions? - Yellow Spots

15 years ago

This is my first time growing tomatoes from seeds, and so far everything looks good. However, I have noticed that some of the plants have these yellow spots on them. This is a recent issue and I am becoming worried. Does anyone have any idea what it is and if I should be concerned?

The plants are under fluorescent light for about 18 hours a day and I only water then when the soil gets dry.

Please take at a look at the pictures below.

Thanks in advance!

I wouldn't worry about it yet, unless it gets worse. Could be a nutrient issue. I noticed slight yellowing between the veins on some of my plants...never got bad and doesn't seem to be a problem for me.

But keep an eye on them, in case it turns out to be a serious deficiency or a disease of some sort.

Your tree looks great; so don't stress. Whatever did that damage to a few leaves is not there now. BTW 12-4-8 is the perfect NPK ratio for Meyers; just be sure it has, or you add Mg, Ca, Iron, and Zinc. Your tree shows no evidence of any of those deficiencies.

Yes, the pot looks small and the plant looks underfed. You are giving it only about a quarter of its nutrient needs: Citrus Focus instructions say "Add 10ml of Citrus Focus in every litre of clean water, weekly. If leaves are pale or yellow, increase frequency of application."

Hello! I'm new to the forums, but I got such excellent help regarding one of my orchids that I'm returning. I just found this 5'9 fiddle leaf fig for sale at the local second hand shop for 29$, and I couldn't resist. I've just discovered this forum, and I've read about the importance of soil composition and the difference of a true repot vs just moving to a larger pot, and a lot of other things. So a bit of a lightbulb moment. Now I'm asking if you think my plan for this fig will work. The situation: The leaves are looking a bit dry and some are also a little yellow. The pot looks like someone bought it and never changed pot or soil at all. It looks very root bound. I can't discern any bugs or other kind of disease, as far as I can tell anyway. I have not taken it out of the pot yet, so I don't know the exact root situation. My home at the moment unfortunately has rather small windows, and I'm not sure the light will be enough, but perhaps if I can make everything else close to perfect, it will work? We will change windows in a couple of months though, so perhaps that will make a difference. My plan: I'm going out to buy some ingredient for Al's 5-1-1 mix as I'm not sure I, or the plant, is ready for a gritty mix. I've found a larger ceramic pot (with draining holes, of course) for it, and will repot. But, should I trim the roots? And if I do, should I prune the plant in order for the root system to be able to care for the remaining leaves? My dream vision is a healthy plant with a thick trunk and several branches, so I'll need to trim at some point. Were/How high should I trim? Or should I wait with the trimming? And how do I encourage the top to root? Lots of questions, now here's some pictures

Spider mites! I think I can see them. Looks like (two-spotted) Spider mites on the picture. Take a picture of the underside of the leaves. Or just put a piece of white paper under the leaves and tap the leaves. The mites will fall to the paper. They will look like finely chopped pepper but moving slowly.

oh no...I hope it's not spider mites...they're the devil. I spent over $50 trying to get rid of them off all 11 of my hot pepper plants last year and still never got a single pepper. :( Anyways, I can't see them. I agree with catman (dude, check out my contest post on Tomatoes...you can co-host/help with stuff if u want). They look fine. I say take them off the fluorescent bulbs. Maybe soak the soil good & put in sunlight heat if available.
I'm thinking a tad bit too much heat caused this.

Peace - Steve
