White stains on top sugar leaves?
tototerremoto
started grow question 6y ago
Yesterday I realized that I got some top sugar leaves with white stains. I think It cannot be light stress because I put her at a distance of 3 feet from the lamp and today she has more stains. What do you think? Thanks mates 🙇♀️🏻

Orange spots?!
Can anyone tell me what these orange spots are on my THC Bomb autoflower? They're only on one leaf (the very first one) - the plant has since grown and there's no further sign of it... should I worry? Grow medium is ProMix, using Fox Farm Grow Big (lightly so far).

Whats wrong with the plant? Is it Male or Female?
Hey guys, its day 23 I noticed this yellow spot on plant #1, overall the plant looks healthy, is it normal for it to turn that color at this stage? Ph 6.10 Ppm 205 Feeding only 1/3 of the recommended nutrients (CalMag, Pure Blend Pro Grow) Is it to early to detect its gender?

All my plants are infested of thrips ! I didn't notice before, beginner mistake ! I can see the thrips under the leaves, even close to the buds. I'm about to harvest 1 plant very soon and the others in the coming weeks, can I harvest anyway or I have to get rid of them before ?

No matter how much PH down is added, my water naturally skyrockets back to a 6.4-6.5 because of the reused hydroton (regret reusing it) Should I let the water stay where it is, or should I continue to add more PH down every day? (I think this is damaging my leaves.)

Seltsame Färbung einiger Blätter
Hallo zusammen! Ich beobachte seit einiger Zeit eine recht eigenartige Färbung einiger weniger Blätter an meiner fetten Banane. Die Musterung beschränkt sich ausschließlich auf diese Bereiche, die Pflanze entwickelt sich sehr gut und zeigt keinerlei Mangelerscheinungen.
