I am growing in dirt.... Is that a common issue? I thought it was only coco that had that type of issue. I am giving lots of nutes. I have zero burning going on.... But could this be from over feeding?That's a calcium deficiency, I think. Time to up the doseage, my friend.
Using H&G at a pretty good strength.... PH is always top notch... And if I was over feeding wouldn't they burn?It could be from overfeeding,(salt/waste build up) causing nutelock, PH problems, causing nutelock, or, using ferts that don't have enough calcium. Which one seems most likely, in your situation?
I had just sprayed them... I don't think its from the lights... Out of about 60 plants only 3 or so are doing it. And it is any leaf from the top to the bottom...You would think if I was over or under feeding it would happen to more than 3 plants... I DON'T GET IT.... I am loosing my mind trying to figure it out....what are the water droplets there on the leaf in that pic. it's not burning from your light is it?
Ok cool... How long do I do this for? And do I just give them straight water? Or super low nutes? Or RO water?what makes you think thats not nute burn? I would say it is. Back off the nutrients for those 3 and see what happens
