Hello, do the leaves of the plants get darker if you give more nutrients before they show signs of over-fertilization? I use Canna aqua. I know that if I give too much nitrogen, the plants get darker. But is it the same with too high EC?

High,generally that's the case.Some will straight burn your leaves though.Some strains can take huge amounts compared to others.Auto's are famous for being sensitive although they have gotten a lot stronger in the last few years.

Deeunit1, so it's not the high nitrogen content of the bloom fertilizer that's making the leaves so dark, but rather the high EC? What do you mean by saying that autos are more sensitive? Do you mean that they require a lower EC?

Black discolouration on leaves Okay so the problems with the black spots continue only on one plant. I tried reducing nitrogen and increased calmag to 4ml/g. I defoliated the affected leaves and sprayed with baking soda mix. 3 days later they're appearing again. If I don't get this fixed soon im gonna lose her

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.

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

Dunkle Flecken auf den Blättern.Hey.. On one of my White Widow plants, dark spots have been appearing on the leaves for days, and today I've also noticed the first spots on a Blue Dream.. Can someone tell me what's going on and how I can get rid of it? Removing the affected leaves hasn't helped.
