Some of the leaves are having some yellow dots on them (See pictures) and some top leaves have yellow tips.
What are those dots and yellow tips? Is this a bad sign if so how can i fix it?

With no EC/PPM information it's hard to give an accurate diagnosis. That the pictures are under purple light does not help. Anyway I think it's calcium deficiency, due to either soft water (if your water PPM is lower than 200, there's a high chance this is the cause); or it could be due lockout caused by nutrient excess, those burnt tips support this theory.

The yellow tips indicate nutrient burn. The yellow spots could be a calcium or phosphorus deficiency, but could also be a sign of spider mites. Good luck!

Have a look at my leaves that have turned yellow and red. I've search online and can't seem to find a similar picture. Is this normal due to late flowering in some plants? Is this a nute problem? If I add the needed nutes, will this clear up? What's going on?Week 8

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

are the rust colored spots that start during flowering a fungus? I sprayed with the sulfur and cleaned tent and it still happen is it from the temperatures being too low and humidity too high at night? Does it hurt growth and thickeningcof the buds? What does nute burn look likeWeek 9

Lila Stängel - Nährstoffmangel?Hallo zusammen,
ungefähr eine Woche, nachdem die Pflanze mit der Blüte begonnen haben, haben sich die Stängel der Blätter rötlich/lila verfärbt.
Meint ihr das kommt von der Genetik (Auto Overdose - Divine Seeds) oder könnte es sich auch um einen Nährstoffmangel handeln?Leaves. Color - Red or pink
