Matina Tomato Leaves Curling Down
Comments (5)First thing you want to do is move your light closer and get a fan on your plants. This plant doesnt look like its been in hydro for 4 month. Its very tall and little to no under foliage. With your tomayo gettimg edema, I would suspect the same thing beginning to happen here. Closer light and fan should help tremendously. I kepy plants only 1-4 inches from my t-5`s. They don't get too hot and benefit more from the closer light. A fan helps keep things cool, but more importantly helps the plant transpire. Give it a shot and followup a few hours later with status....See Moretomato seedling with curled and sligh greenish purple leaves
Comments (1)I do not know your problem but maybe this will start you. If the problem is a deficiency, noticing whether it started on the older or younger leaves first might narrow the cause (if they are big enough). Nitrogen & phosphorous deficiency symptoms first appearing on the older leaves. Symptoms on the younger leaves include Calcium & Sulfur. Purple leaves on the lower surfaces can be seen with a Nitrogen deficiency & leaf curl downward is seen with a Sulfur deficiency. Leaves curled under are seen with a Nitrogen excess. Slow growth can be due to Nitrogen, Phosphorous, Potassium, & Sulfur.

If you think you might have a disease you could post pictures on this forum. Any symptoms of leaf spots, abnormal veins, stem & bud character, plant size, etc., might help identify the cause.

Comments (3)sorry, I do not know how to make them smaller!...See MoreTomato seedlings - leaves are curling downward...Are they OK?
Comments (21)" I actually think it's when true leaves are adapted to the lower radiation levels of artificial indoor light that the plant becomes prone to sun damage. I would guess that, as soon as the growing tip starts producing the first indications of true leaves, that's when you have to start being super careful about sun damage." I'd agree if for no other reason than the cotyledons alone aren't capable of photosyn, only the true leaves. But many times that distinction isn't included in the advice. Shoot I have lost trays of young seedlings sitting in the greenhouse from sunburn, much less outside. What I take issue with is the broad statements made on so many blogs. Utube and even sometimes here, that putting your seedling out in full sun is no problem - no guidelines, no qualifications, no age guidelines, no distinction between full sun in AZ vs. full sun in MN, etc. Newbies read those claims and next thing you know they have a tray full of sun and wind burned plants or dead ones and want to know what happened to them. There is a thread running on this right now over on Vegetable Gardening with pics of young seedlings that were put outside early on and the damage that happened. So the safest approach is to not do it unless you are experienced and really know what you are doing and if you are going to do it be prepared to possibly lose some of your seedlings. If you have 200 of them it is no big deal but if you only started 10-12 plants it can literally wipe you out. But people get impatient and they don't want to bother with proper hardening off procedures. Their choice but they have to pay the price. Dave...See Moredonna_in_sask
