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.

Weed doctors to the rescue Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

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?
