Yellow spots on leaves

TrainTrainstarted grow question 5y ago

Does anyone know what these yellow spots are? They only appear on about 5 leaves near the top of the plant. I've googled but can't find anything quite like it. I checked under the leaves & there are no bugs.

Fabric planters ? If so i would make sure your entire root system gets wet after you water your girls look a little on the dark side, maybe cut your feeding back some. If their fabric pots look to see if it is pouring out the sides when you water

Losing colors :'(I watered only 2L of water without nutrients this week (pot 30 L) You can see it on the diary photos, the plans have lost their colors (yellow). I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion Thanks !

Hojas bajas amarillas Tras un día de sol sin un calor excesivo he detectado hojas amarillas en la parte baja de esta auto mutante (2 plantas de una semilla). La he alimentado con algunos ferilizantes, incluso calmag en una cantidad adecuada para la prevención... ¿Qué podría significar? ¿Como parece?

Bottom leaves yellowing at beginning of flower So my plants have been flowering for about a week now and the lower fan leaves are yellowing with brown spots. Should I be feeding them more of the flower girl I’m using or is this a deficiency of a specific nutrient? (following dr earth feeding schedule designed for cannabis)

Too close to light? Nute deficiency?Yellow leave with brown spots, what is going on? Showed up really in the last 2 days. It got a half strength dose of big bloom every other watering, the light was pretty close about 6-8 inches away. I didn’t check on it for 3 days so it grew a bit and was super dry.
