Amnesia Haze attempt two

Hi there Kees, so this is what happened : every time you water you’re slightly overwatering which is “activating” or “releasing” the nutrients in the soil a bit “too much” so over time there is an excess of Nitrogen which is causing “lock out” meaning the plant is not taking any more N, and of course in veg it does need N. So now you see the symptoms of N deficiency , but you know there is no deficiency. This you can see first on the leafs , the puffy space between the veins of the leafs is from overwatering, you can also see them wrinkled . Then the yellowing starting with the oldest leafs first , moving upwards . Hopefully there is not too much damage. You can fix this by following a more strict wet dry cycle , try the pot lifting method if you want to learn never to overwater again. Hope this helps ! 🚀

Overfeeding for sure. Measuring the EC of your runoff helps with this. If the EC in your runoff is going up after each feed, them you're probably giving too much nutes. In this case the dark green foliage is a classic sign of too much N, but it looks like you have other toxicities as well. Almost never trust the feeding schedule on the bottle. Always start at 1/4 and slowly increase it. You'll rarely need to go past half strength in my experience.

Try going to a plain water/plain water/feed/plain water/plain water/feed schedule. If you are feeding each and every irrigation, you will get a build up of fertilizer salts, especially if you are only giving 50-100mls and not flushing the substrate properly. The symptoms appear very much like nitrogen overdose, and if you are feeding each time you irrigate, this would be plausible. Unfortunately these things build up slowly over time, until the plant can take no more and before symptoms appear, but by then the problem is intensive. Fixing the problem is also a long and slow process and is not something that can be remedied in a week. Flushing with lots of plain water can be dangerous too, as it may release more nutrient salts from the substrate and cause a bigger problem. Therefore, switching to a water/water/feed routine may be the first option in preventing the problem from getting worse, but there is no easy or quick fix. Hopefully by doing so, your plants new growth will be much more normal and some slow and steady healing can begin. With this water/water/feed schedule, you should be feeding your plants every 8-12 days, depending on how fast your substrate dries out. In about 3 weeks time, I would suggest giving more plain water between feeding, maybe a litre or a bit more, to begin flushing the substrate between feeds and to prevent from the nutrient salts building up again and causing your plants ongoing problems. Hope this helps,............. Organoman.
