SSFito173started grow question 5y ago
First week of flower and this starts happening. I flushed with 1 gallon r/o water hopefully it doesn’t continue. Anyone knows what deficiency is this?

It look like light burn or a micro nutrient deficiency (magnesium, copper etc).
If your lights are the proper distance and your feeding the plants a well rounded diet, then i would double check your ph pen is accurate. Recalibrate it if possible. You may be having ph swings too low or too high.
Happy growing. ✌️

Mancha en hojaA que se debe que estén así algunas hojas? Es deficiencia o exceso? Regaba con 1000 ppm pero vi algunas puntas quemadas y color verde oscuro en las hojas así que lo fui bajando poco a poco hasta llegar a 500 ppm, y hoy note esas manchas(el agua drenada da 750 ppm)(coco y perlita)Leaves.

Leaves browning in multiple spots Lower leaves yellowing but have green veins.One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?4y ago

I have only been using CalMag at half strength.. I normally go full.. So I suspect its Cal def.... But never seen it this color.. Different strains can show differently tho.. Help! Just on the 2 remaining fan leaves.. Not spreading to branches... Yet.Week 4
