Brown spots on tips of some leaves

handamanstarted grow question 5y ago

4 leaves affected on only one plant. All plants are receiving same feeding and are from same clones. Based on photo and googling it looks awfully lot like P deficiency? I'm still in vegetation phase though. I'm feeding with Advanced Hydroponics Grow + Bloom + Micro based on chart

and no need for using Bloom atm,, forget the charts, sttick to your vegetation Nutes ( and only the vegetation + Beneficals) otherwise it adds up to much nitrogen. and they have no need for P and K atm

Nope no P DEF IN THIS STAGE looks like you spilled something on them besudes the leaves are quite darkgreen, so pay attention with the Nitrogen you add.

Brown Patches on Older Leaves Slight yellowing and brown mottled patches. Only on one of the two plants and they’ve been treated and fed exactly the same. On some older fan leaves, no signs of anything on new growth. Anything to worry about at this stage? Maybe just a sensitive pheno? Any advice appreciated.
