What do these spots mean?

First grow! This plant is about a 2 1/2 week old from seed. Grown in Fox Farms Ocean Forest under about 80w CFL right now. Watered with tap water that has been left out to evaporate chlorine and at 6.5 PH. Was in a solo cup until yesterday and just fed 1/4 strength Grow Big for the first time. Just noticed the leaves today. Any idea of what this is? Also attached a report of my water. Is this nute burn, a deficiency or because it was getting root bound?

Thanks for any help or advice!

You may have some spider mites. If you do, spray your plants don't forget to get UNDER the leaves too, they like to hang out there.

It's possible it was root bound. What size was it in?

Looks like your feeding is right where it should be. No burn. It could be splashing when you water with nutes.

It does look similar to mite damage like Rob says, but I didn't see any webbing, so I doubt it's mites.

It was in a 16oz cup. Transplanted it yesterday and that was when I noticed the spots. A friend mentioned it could have been root bound also and that was the cause? I've checked under leaves and I can't see any evidence of mites but I could be wrong. It doesn't seem any worse today.

Thank you guys for the help. Would it be worth using different water and using neem oil or should I just let it be for a few days?

When you transplanted, was it root bound? You would notice. In a 16oz cup, shouldn't have been but depends on the diameter.

Didn't even notice the water test. Harley has the right idea. That is a little rough. Do you drink that?

Just keep an eye on it. It's best to only change things if you need to.

The plant is looking ok..check for pests closely, but it may have been a bit too big for the cup and /or perhaps waterings were not great? Appears to be calcium related. Your water is not great, very high alkalinity at 177 ppm! High bicarbonates, higher sodium, which competes with calcium, if it hasn't caused problems yet..it may once she starts eating and growing more. Calcium deficiencies will usually pop up with watering/transpiration issues. Too much or too little water, or if the plant is not taking the water up in a proper manner (too fast or too slow)..calcium is the first element to suffer, and it will appear at the farthest part from the stem..where it takes water the longest to get to. If the plant drinks too slowly (or not watered often enough with enough water), calcium cannot get to where it has to go..if the plant drinks too fast (too hot/dry surroundings), then the calcium will get deposited to the lower parts of the plant first, and the tops will get the water without the calcium in it. Environmental factors are usually the first cause of calcium deficiencies (assuming one is using some type of fertilizer and/or tap water which contains it).

Okay cool. The roots were reaching the bottom and wrapping a bit, it didn't seem root bound to me but I don't know quite exactly what that would look like. I get this water from the tap outside which is unfiltered, the water to the house gets soft water filtered and through a carbon filter from the fridge I believe which is what I drink.

Yeah my water is pretty hard here. My waterings were pretty good I think, I just monitored soil until it was dry about a knuckles length down. Was watering about every 5 days for awhile but up until transplant yesterday it would be dried up by the next day. It was in a 16oz cup up until then. That's interesting info thank you for sharing, my humidity is at about 40% and temps at 75F I wonder if that is too dry...the water to my house runs through a soft water filter. Would that be better than this unfiltered tap water?

Check the ppm's on the filtered tap, maybe it's better. The biggest issue is the bicarbonates/alkalinity of the water..sodium isn't very high, but compared to calcium and magnesium, it's a bit too close to them. testing water with the knuckle test isnt always accurate! Again, depending on your surroundings..maybe the top dries out faster..maybe a fan, or heat forces some pots to dry quicker near the top..the best way is to judge by weight of the pot..that never lies!:) Do a search on VPD, to get a better understanding of the relationship between temperature and humidity. The charts may help you get a better grasp of it. Your humidity is a bit low for that temp..especially in veg.

Maybe give them the filtered stuff if you can.

This is awesome info Blitz. Thanks for all the help guys! I think I'm gonna try mixing my tap with either distilled/RO for the next few waterings and see how that goes
