Seedlings don't need any nutrients for a good 12 days at least. Stop giving nutrients, water when dry, it will grow out of it.

At what stage do leaves get darker ? This is confusing
I overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

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.

Listless plant
What would cause this specific plant to look so droopy and sad? Had to cut out some totally dead growth. I’m at week 7, is it too late to help it?

Dunkle Flecken auf den Blättern.
Hey.. One of my White Widows has been getting dark spots on the leaves for days, and today I also noticed the first spots on a Blue Dream.. Can someone tell me what’s going on and how to get rid of it? Removing the affected leaves hasn’t helped.

Heat stress?
Heat stress and can it be saved? Had to go away for a couple days. Hottest days of the summer mid 90's, full sun, but well watered. This is my first ever grow (auto & outdoor) and I expected about 1 week left until harvest. Thanks

Dark tips
it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

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?

Today I noticed 🍄mushrooms popping up with GiSCele. Does that matter? Are they🍄poisonous to girlies? Don’t bother me,but I dunno🤔. I recently started using 🦇 bat guano and have a feeling that’s what encouraged- kinda cool if I see Smurfette sunbathing on 👙🆒👍🏼
