Could well be a potassium deficiency appearing or some lightburn as it is quite even and uniform.

Nutrient or water temps? Water temps between 15⁰C and 20⁰C but usually closer to 15⁰C.Not sure if it's a nutrient deficiency/excess or water temps. Please refer to pics. 2/3 plants are showing light green and yellow tips. New growth seems light in colour as well.
pH - 5.9 to 6.1
Daytime temp - 75⁰ to 79⁰
Night temp - 67⁰ to 70⁰

White tips on leaves and veins on the other oneHi guys, what should I do to fix these problems?
1) I see a lot of white tips on the leaves on the left one.
2) On the other hand the right one leaves show weird veins or am I wrong?
Please take a look to the diary for the info you need, thanks a lot.

Nute burn or gnats?Is this nutrient burn or fungus gnats? I started to see signs of my leaves starting to lighten. So I moved the light away and it didn’t solve it. So I started flushing, which seemed to help at first but because the soil is always wet I’ve got lots of fungus gnats flying around.

Seedling issueHey guys my seedling got a little pale between the veins and started to get rusty on edges of leaves. I'm sure its due to unfavourable environment as it did get a little dry and humidity wasn't as high as it should have been. Looking for thoughts on whats up?

Is this light burn?I have discoloring on the top leaves of the plant. It started today and I think it has to do with the lights, so I‘ve turned them down and moved them up about 1-2 inches. Can anyone confirm if I’ve diagnosed it correctly and if not what the issue might be. Thanks.

My autoflowers are getting bright spots on leaves. What could the reason be? (Week 3, no nutrients given yet because they are in all mix)What could the reason for those spots be? I suspect one of the following:
Nute Burn because my Autoflowers are in 75% Allmix.
Cal/Mag deficiency because my water is very soft and a bit high in natrium.
Light Burn because the DLI was ~25 when it should be 20
