Burnt leaves? Nuts burn or something else?

Hey friend, When I look into your diary, I see alot of problems there.First I see curling leaves , may be caused due to over watering or nitrogen toxicity.To fix this, let the soil dry about half to one inch down from top.You have already switched to flowering circle.So stop or reduce feeding nitrogen rich fertilizer.Another thing is burn tips.They could be from nute burn due to excess of nutrient.Soil don’t need much nutrient.You should reduce your dosage strength.I hope you are not using folior spray fertilizer.Cause they could cause burn tips easily.Last thing is I found out is some brown and dry crispy leaves at the bottom.They seem to be Cal-Mag deficiency to me.So add more Cal-Mag.Remember always adjust your water pH around 6.5 whenever you water.In this way you can get rid of those in no time.Happy growing.. ✌️
