Yellow Spots

Seldom_Seenstarted grow question 4y ago

Can someone please tell me what these yellow spots are. They are not uniformed circles. Found them on two leaves. I removed both of them. First two pics are taken under a scope.

Most likely from leaves getting wet. When the leaf has water on it the light gets magnified on that spot causing it to burn. Similarly to using a magnifying glass when you use the sun to burn ants when you was a kid.

Looks like you might have splashed some water on them while the lights were on.

Spot on seedling Slow growth - Pest or not?Planted some Pineapple Express Autos a few days ago. 3/4 are developing well so far but this one hasn't even gotten true leaves yet. It has this weird mark on it, has been like that since it sprouted so I figured it would be fine. Is this cause for concern?

Somethings up with my baby girls!?Help! I have no idea why my girls aren’t happy?!?! Their leaves appear wrinkly (like when you stay in the bath too long). They were stretching when they first sprouted so I moved the light down and turned up to 💯 Shouldn’t they be a bit bigger by now?!

Small marks on leaves a concern?I noticed only a couple leaves out of a 4x4 gg4 grow show weird marks. Just wondering if it's cause for concern since it's my first grow. Otherwise they appear to be perfectly healthy, growing great and praying going on 4 weeks into flower.

Please help!Hi grow bros. This is my first ever grow attempt with some AK-47 seeds. I am about 8 weeks in and have had to move plants indoors due to extreme heat here in Australia. Quite concerned at these marks on the fans that seem to be getting worse. Plants are inside now on 16-8 LS.

Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?
