Hey y’all, I have a slight issue with my fan leaves. Currently week 3 into flower and I have these yellowing tips that eventually are turning into brown dead tips. My feeding schedule is very meticulous. I cannot diagnose whether the issue is nutrient related or light/heat related.

———————————————————————
Cycle - 12/12
Nurients/Gallon:
MegaCrop Plant food - 3.75g
Mega Crop Sweet Candy - 2g
Botanicare Sweet Raw - 5ml
Botanicare CalMag Plus - 5ml (every other feed)
Botanicare Hydroplex - 2.5ml (every other feed)
Flower Fuel - 1/4 teaspoon (every first feed of the week)

Temp/Humidity- 78F/45% (lights on) / 64F/58%(lights off)

You need to check it beforehand so you know what your feeding it... ppms
Get a microbe product and use it once a week.

Prob the new growth and in the 3rd week they are probably needing less N and just a lil toasty

I went back from 5g to 3.75 on the MegaCrop because it’s 10% N (all purpose nutrient feed) so I’m trying to use less of it every week and supplement nutrients that are higher in P and K.

doesn't seem to be out of control but I'd back off the nutes a tad. if you were measuring your EC in youd be around 1.5 now?
