@gray_wolf I think you may be right. Sometimes it can be light burn. But the tips of your plants aren’t all effected.
What’s your ppms? Or ph
Also growers recharge is good for this. Helps balance her out and gives the plant a chance to absorb more Potassium and phosphorus. Before fuckin with your nutes. Check Ph
If PH is good. Either cut in half
Or just use less.
PS:
This is why I go true organic.
PH and over nutes are never a prob.
The plant takes what it wants. Instead of you telling it.
Good luck man
