So I planted three AK auto seeds 7 weeks ago. They were transplanted into Happy Frog soil exactly one month ago. Things were going along fine until a few weeks ago when one of my plants started getting dark spots on the leaves, which would then shrivel up to the point they would need to be removed. The plant kept stretching up to the light and budding but now almost very leaf is gone and I still have at least a couple of weeks to go (I’m guessing). The worst part is that now my other two plants are showing the same issue. I thought it was a nutrient defiency since it started on the bottom leaves. So I started with adding 10mL of Florobloom, 60 mL of Fox Farm Big Bloom, 5ml of Cal Mag and 5ml of Silca per gallon of distilled water every other watering. I am careful to adjust the pH every time After adding nutes. I water to enough runoff to get ppm (usually around 950). I know Happy Frog is a hot soil but shouldn’t it have more than a couple of weeks of nutes? I’ve even tried a little molasses once to help. After two weeks this doesn’t seem to helping. The first photo is of my most affected plant - the second of my other same aged plants starting to do the same. Thoughts?
The only difference on the other plants is that the discoloration is on the ends of the leaves - maybe Nute burn?
