Ahh RIU I HAVE A PROBLEM!.

Hey RIU currently flowering and i think I have a deficiency. I will say that I have moved the plant away from the light 2 days ago and I also stopped spraying the leaves just before the light would come on sometime ago so I can't explain these spots and drying on the leaves. My setup is 400w hps about 3ft from plant and growin in ffof, temps around 75/85 degrees with light on and about 70/68 degrees light off.

looks like a calcium deficiency. Is your PH proper? If it is you may
need to add a cal supplement.

Im sure one of the more experienced growers will chime in to give a better
diagnosis.

Calcium and Magnesium? Most nutes don't have enough, GH certainly has big lack.

What are you feeding?

My esperience with the light is that as long as I'm not drying and browning the short hairs, so to speak, on the flowers, I'm OK.

Well all the hairs are fine I mean there still kinda white as cotton lol but I've only used water and beastie blooms once at 1/4 strength to a gallon. I'll try to get some cal-mag and try that.

The yellow spots are Ca., and the rust colored spots are K.
A good feeding should help.

Do you ph and ppm your water? Could be your water source if you are using tap

Are those spots Ca or mites?
It's so hard to tell in pics. In person, easy.

If there are larger spots just like it around with a brown center... then ca. If there are not and the spots are more white than yellow, spider mites.

I pH my water and soil and everything checks out fine. I use to mist the plant before the lights would come on but I don't do it anymore,
