Title: Tomatos - yellow leaves?
Post by: Spookyville on May 15, 2007, 10:30:24
Forgot to post this last night. Some of our toms have yellowing lower leaves (upper ones seem fine) which have now gone lightish brown.

I noticed a similar problem in th egarden centre when they were still in the smaller pots.

I must admit the ones were affected were left in the smaller pots probably a little too long. I am hoping it is something to do with either watering -= over/under or a magnesium deficiency etc and that now once they are in gorw bags they will recover and propser.

Having never seen blight symptoms first hand (and the pics on the net show dark patches not yellow) I am hoping it is not blight.

I will try and post a pic tonight to show what I mean...

any advice appreciated. thanks.

Hi Spooky, it sound like they may be hungry as well, (if you left them in small pots, they would have used up all the food in the compost , so the plant will move the food from the lower leaves to keep the top ones growing , --photosynthesis, ) give them a tomato feed as well two -three times a week, you'll see new life, greener leaves,
hope this helps
windy ;)

thanks. had a feeling it was something like that.
Will give them a tipple of tomatorite this week :)

should I remove the affected sets of leaves or leave be?

Don't know about most people but I snip off any leaves that look discoloured.

I would remove the affected leaves. It won't harm the plant, presuming it's not the majority of the leaves. I've just removed the lowest 2 sets of leaves from mine in the GH, because I want to put pop bottle collars round them to add a bit more compost over the feeding roots, as they are starting to show above the existing compost.

We moved some of our pots outside a little too early, and the lower leaves have subsequently got a little wind-burnt.  Nothing to worry about, and the plants are doing well apart from that.

Quizzi, Hi,

Pop bottle collars  ......
sounds an interesting idea, could you start a new topic and tell us how  ;D

thanks

I am guessing 2 litre bottles (pepsi max, coke etc) then cutting them into "rings" at a certian length then ppositioning them around the stem on the plant on the growbag or whatever.

home made simplified veriosn of those grow pots you can get I reckon. top stuff :)

Spot on spooky, although you may have to split them lengthwise too and reseal with Duct tape if the plants are already quite big.

It looks more like Magnesium Deficiency, Give them a dose of Epsom Salts, half ounce to a pint of water or a foliar feed with some thing containing Magnesium (Mg)
