Brown Splotches on leaves

SgtDoofystarted grow question 2 years ago

I am dealing with a brown splotch issue on the leaves. Does this signify any particular deficiency?

wie @gottagrowsometime sagt. CalMag Sperre oder Mangel. Mit PH reguliertem Wasser und 20-30 Prozent Abfluss spülen. Dann wieder leicht andüngen + kleiner extra Dosis CalMag.

I'd have to strongly disagree with my fellow growers This is typical calmag. If it were K, I'd be seeing edges crispy and so on. Not on this. Also with the mag signs. Its just a typical calmag pal. As you're still in veg. I don't see it been K at this stage. If it were I'd of seen it coming up. I can see light mag on the week before You can add Epsom salt Foliar spray. Or an organic calmag r just feed it into sub. Good Growing

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

Does anyone know what’s going on here?Hey I have the following problem: A week ago, I bought some cuttings from a seller, but they turned out to be infested with thrips.

4 times same genetic but one has hanging leaves The top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?

First grow with autos, are these growing too slowly after a week?It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

Super thin leafs at the Top The leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?
