leaf problem
CloneKingzanswered grow question 5 years ago
Heya konopek!
Looks like you may have some critters on the undersides of your leaves. Have a look, they may appear white, green or brown. You can use neem oil to get rid of them, use an insecticidle soap or water with a drop or oil based soap. I spray the canopy, the undersides of the leaves, the stems and soil. I do this a few times a week and when I no longer see any I continue for one more week to be safe.
Have a close eye, they can be really small!
Cheers and goodluck

Hey Growmie,
Looks like thrips are causing the issue. The way you get rid of these pest is by using a mild insecticide like insecticidal soap or neem oil. Hopefully I answered your question and remember Happy Growing and Free your mind one puff at a time.

Those are thrips, get ProNeem so you can apply in irrigation and spray, or neemazal for spray only, those work wonders.

That's thrips. Check everywhere especially under the leaves. You'll find 1..... or 30....
Neem oil kills them. They are probably on your other plants too. Best of luck!

What's going on with this leaf? Changed colors overnight?Woke up to find this leaf in the back of my tent. What's going on here? Day 46 flower. Recommended flowering of 60-70 days. Looking at my timeline, I figured I had maybe 1 or 2 more feedings left before I started giving just water till the end. Should I worry or is this normal?Leaves. Other

Too little calcium in early flower?I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed.
Is this a calcium deficiency, and if so, how can I address it?

Please help me diagnose this one :)It is a very slight orange spotting that almost appears like the start of a calcium def, but without actually creating necrosis. It looks almost like the orange spots are on the surface of the leaf. Nothing on the bottom and it's only showing on the one fan leaf.Week 4

Seltsame Färbung einiger BlätterHallo 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.Week 8
