Planting Annual Flowers, Brussels Sprouts, Collards, Tomatoes. 4.23.18
Hi Joan,Thanks much for the links and pointers (funny, I had been on the site for the 1st one earlier today!) Of course I just bought seeds recently but I think I’ll still check out the disease resistant varieties, like you suggested. Since my 1st post some of the leaves developed even more, smaller brown spots, and last night I discovered a white substance on the surface of the clay pebbles of nearly all the pots, both totes. Argh! Disappointing for sure, but, at the same time I’m kind of glad this is happening early on, when I’m in the learning and experimenting stages anyway.I believe I’ve identified the white substance as salt buildup, not a mold or disease, and most likely it’s related to the nutrient solution. We did have some problems with the scales when weighting that out and it wasn’t as exact as it should be. Another thing to remedy!As for the brown spots, I’m thinking that may have occurred after the temp. in the grow room was too hot for a couple of days last week and I should have had a fan going to circulate the air in there sooner. Lettuce doesn’t care for heat, and add in the humidity, in a room as opposed to outdoors, and not enough air circulation. It’s easy to see how that would be entirely too hospitable for molds and diseases. So, good air circulation at all times, watch the temp. and humidity. There are a couple of other mistakes I was making, like the way I was harvesting leaves (not enough). The greenhouse mix is ready to harvest, which we’ll do tomorrow night and use with some of the romaine. For the next grow I’m aiming for much more accurate weighing of nutrients, and will plant bell peppers, swiss chard and one new lettuce variety.Nice to meet ya’ll! And thanks again.

Thanks anyway, and it's nice to meet you!
Daniel, pretty daffodils and gorgeous blooms.
Welcome Bead Bum.
Daniel, I agree about the daffodils. Very attractive.
Can't help you, BB, but welcome, anyway!
BB, I enjoy seeing the process you use to grow lettuce indoors. The plants look healthy and very appetizing, except for the wilt that you point out. I think the only leaves affected are the older leaves, and they may just be older and tired. Or, they may have an infection with a disease, usually molds caused by too much moisture, or a virus.
Use keywords to search for identifying, treating, and preventing diseases and pests in plants, i.e.
"hydroponics, lettuce, diseases, pests."

One remedy is to plant seed varieties that have resistance to hydroponics grown lettuce diseases.
I would simply pull off the affected leaves and dispose of them. The others should be healthy and delicious if washed under cold running water.
P.S. this is my first grow, so I'm a novice at this kind of gardening.
Hi everyone,Are there any indoor hydroponics growers here? My husband and I recently set up an indoor growing station and are using the Kratky method. Right now we’ve got romaine, greenhouse mix lettuce, spinach and basil growing. We were pleasantly surprised at how fast the lettuces took off. I’m keeping a growing journal and taking pics regularly. Everything was looking great 3 days ago, but today there are brown spots on some of the romaine leaves, and I think I’m in mourning, lol. I’m posting some pics that show the growth stages from 3/11-4/5 and a couple from today of the brown spots. I think it may be a mold of some kind, but haven’t been able to determine for sure. Anyone have experience with this, advise or ideas? Do you think it’s okay to eat the romaine after removing the affected leaves? Thanks for any input you might have! *We're now thinking this may be rust.
