Leaves problems

I have to disagree with the last review. To me that's just a calmag problem. Add some CalMag and in a day or two the deep dark greens will return. Nitrogen burn is that itty bitty burn you have on the tips of the leaves. Just add some calmag.

My thoughts on this one is a few issues going on. One of your plants looks like its got to much nitrogen and not enough magnesium, phosphorus and potassium. There may also be a heat problem. If your feeding with every watering you need to cut that out and at least alternate. Also you need to get run off if your not already doing that. I would be tempted to give a good flush with ph water. Then next feed at 50% but increase your P and K and lower your N.
