Put a plastic bag over it, it looks like it could use some humidity.

Hallo, werden die Blätter der Pflanzen dunkler wenn man mehr Dünger gibt bevor dass sie überdüngung Erscheinungen haben? Ich nutze Canna aqua. Ich weiß dass wenn ich zu viel Stickstoff gebe dass die Pflanzen dunkler werden. Ist das aber auch so bei zu hohen EC?

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

greyish leaftips and dieing branches after topping
the highest branches died after topping. It looks to me like they had the same symptoms like some new upper branches are developing now. It looks very dark & feels soft Temps were 17-19°C & Humidity was 90%+ Water should be PH5.9, think ph reader might be wrong and ph is too low?

Bud leaves turned black
Top leaves turned brown overnight, That day I did come home to a disturbing temp off 31oC . It’s the black Mini leaves in buds that are worrying me more. lights came on accidentally for two hours so gave her 16hrs dark and back to 12/12 This may have contributed.

My seedling doesn't look so good.
This is my first coco grow so could be possible that I made a mistake. The other three seedlings are super healthy but this one has this weird thing with it's leaves. Somebody seen this before? I gave them some root juice and fertilizer before transplanting with ph between 5,5-6.

I’ve never seen this before?!
Weird spots on leaf’s I’ve never seen before. Growing in coco with dry amendments and worm castings. Ph 6.7/6.5. Just gave some compost tea earlier today. And earlier this week some GH calmag because some of them are showing deficiencies for that. But what are these weird spots?
