Purple underside leaves and stem on tomato seedling
Comments (6)well firstly, your images aren't showing up and the broken image links to a pot site. But ASSUMING you really are growing tomatoes, what is the pH range you're maintaining? have you considered a commercial pH adjustment. I believe they typically use phosphoric acid and from the name you can guess what a byproduct of that is. If your plants have roots coming into contact with the nutrient or coming out of your medium, you're using too weak of a solution. a full strength veg solution is what you should be using. The only other thing I can think of is you've somehow locked up the phosphorus when you mixed up the nutrient batch. is there a precipitation in the bottom of your reservoir? Here's a chart that shows nutrient availability versus pH. Print it out. its a very valuable to to have.

Comments (6)Here in Florida my plants did the same thing when I started to harden them off. They did well in the shade but as soon as they hit the direct sun light a lot of leaves got a purplish orange tint to them. I don't know if a florescent light could do that, but that is what my plants looked like when they hit the direct sun. My plants were almost a foot tall when I started to harden them off, they are fine now. Sam...See MoreTomato seedlings getting brown tips and leaf roll
Comments (10)Jeanna, I started them in miracle grow seed starting mix and watered when I noticed the soil start to dry. They were all doing really great untill they got about 4 or 5 inches tall. ( not all of them ) I did mix a tablespoon of miracle grow liquid feed per gallon. I fed them with that twice. I started in mid February and probably gave them the first feeding maybe 15 days later and then again once I noticed that some of the plants were having problems. I transplanted them all to 16 oz cups. Some of them I gave the miracle grow seed mix and some I made a mix of 2 parts soil , 2 parts peat, 1 part perilite , and 1 part ( the little white things , can't think this morning). Anyway, the ones that were doing ok are still doing ok. The ones that were having problems still seem to be. Some may be a bit better. The problems are on the old leaves and the curling is turning up. Not sure? I know tomatoes are hesvy feeders but I don't want to roast them....See MoreTomato Seedlings Slow Growth and Cotyledon leaves drying
Comments (10)The medium is peat moss (zero nutrients). The lights are mounted to a scrap of plywood suspended 1-2 inches above the tops of the seedlings. And it may look like I have the tray wrapped in plastic, but it's just a barrier to keep the cats from snacking or walking over the tray. The seeds sprouted from about 3/5 to 3/16 (peppers a little slower). The natural light that they do get is shaded a little from the mounting board right now. Only the row closest to the slider gets any real sunlight for now, and those seedlings are leaning ever so slightly toward the artificial light. I'm starting to think the cotyledons are sunburned from the water left on the leaves after misting. I'm just worried that the true leaves won't grow before the cotyledons have dried up...the first true leaves were poking up maybe 2mm last night. I keep tricking myself into thinking these are older than they really are (24days). I was quite satisfied with my results until I saw the slightly browned cotyledons last night. I'll have to take a pic of the "burned" leaves tonight...the OP pic is from about a week ago, and I guess misleading. I'll be back home in a few hours... the spots weren't there last night, so maybe these got too wet for a few days? It's hard to take a pic of such small leaves! These are the San Marzanos...one is a faded green. I'm hoping the true leaves will grow FAST!...See Moregorbelly
