Issues with leaves

I wouldn't say there are any deficiencies, but way too much feeding going on, especially with the nitrogen. Do you feed every time you water? If so, give them just plain water every third or fourth watering to reduce the build up of nutrients in the substrate. At this stage, I would be giving the substrate a chance to "settle down" by just giving plain water for the next 3 irrigations/waterings. Your plants will still grow fine, I bet there is more than enough built up nutrients in the substrate to keep them going for the time being. Remember, it is easier to give your plant little food often, rather than a lot of food all at once. Slight under feeding is easy to correct, but even slight over feeding is a big problem to correct. Try half strength when you return to feeding them after the plain water schedule (if you choose to try my suggestion) and I am sure your plants will be much happier and grow just as fast as they are now. Hope this helps,... Organoman.
