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

Seedling diagnoses
These seedling are 10 days old but have slowed in growth and appear droopy. They are in promix hp with perlite 18/4 lighting roughly 76 degrees 55-60% rh. Watering daily @6.1 ph 220ppm due to the heaters drying the mediumand cardboard containers. Don't think its overwater but idk

Crispy leaves on some lower fan leaves (day after increasing light strength)
What do you think the crispy leaves were caused by? Too much light? Had the light at 200ish watts, (45%) and turned it up to 80% (also raised the light up 4 inches) a day ago.

Low growth rate and yellowish/light green leaves
I am worried about the light green color and slower growth rate. -seeds were new. -ph seems ok -temperature is a little bit high but within range. Actually the tips of the leaves show some purple edges.. any guess?

Rolled in leaves and kinda pale and started to curl up
Leaves have started to curl up on day 5 and down look that healthy, so I have lowered the water level, raised the ph to 5 and doubled the distance to the lamps, did I do the right thing?

Is this some kind of deficiency or a genetics-thing?
What do you think this light green comes from? From looking into several Special-Kush #1 grows, it appears it may could come from this strains genetics - although I'm absolutely not sure about that. For the sake of it i ordered a PH-pen - for now I'll stick to my PH stripes.

Auto seedling discolouration
This discolouration has appeared on the leaves of one of my two gorilla glue autos, it has been there since the first true leaves which makes me think it could be genetic? I’d like to know if anyone has more information on the cause or if anything needs to be done about it.

Pale new growth
Either to much nutrients or to little nutrients? We have had a lot of rain and I wonder if the nutrients have been leeched out.

What's causing the leaves to lighten?
It's day 10 and the first set of leaves are starting to lighten in colour. Is this related to Cal-mag, bleaching from light, or possibly nitrogen? Using FFOF with PH'd tap water adding Cal mag. Mars Ts1000 at 30" on 55%.

Leaf discoloration cause
What would be causing this? Haven't been feeding that much, possible that pH was a bit on the high side but not extreme. I did just defoliate quite a bit. It seems it's only the newer growth that's affected

Spots in Leaves
Today I noticed these spots in one of my plants. It doesn’t seem to be any of the usual symptoms (as far as I could check), or at least it’s not clear for me... aside from having these spots in a few leaves, the plant looks healthy... do you guys think I should be worried ?
