Looks like phosphorus deficiency. Too much water can cause this or it is just purely lacking it. Good luck 👍

In coco you can not have too much water in one sitting. Is your run off ph 5.8?

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

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?

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

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?

Black spots spreading // Need your help!
Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...
