Brown spots watering in coco multiple times a day
Seeing brown spots on the leaves. Assuming it's a calcium deficiency. Added another ml/gal of Cal-Mag for the daily feeding. Besides that, what else could it be? Also, at what point do you water plants in coco twice a day?

What’s appening to the little northern light auto?
so far I have only given her the rqs growtablets plus a break of plain water and given this reaction today I have also started to give her some advanced nutrients (MGB) is it just a delayed nutrient problem or should I worry?

Brown spots
I'm having what I think is a cal deficiency. Ive been using calmag for a week or so now. Just curious if this will ruin my end results? It looks pretty bad. Buds still look nice though. Any thoughts?

Spots on leaves and little twisted...
Spots started slowly showing when it had a different 600w light, too much heat back then, this started a little "save operation" changed light, made the plants look a bit healthier but now it looks like the spots have spread and also affected the leaves above... Are they healthy?

Damaged leaves
I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected

Brown spots, droopy leaves
I'm trying to figure out what's wrong with them. Leaves look stiff, droopy and feel a bit dry. Am I overwatering? Potassium deficiency?

Yellow leaves - moby dick
The olders leaves started to die and to turn this yellow-brown color. I thought it could be the temperature (I am about to receive my temperature hydrometer to measure that), or over/less watering, or nutrients. The plant looked great a week before.

Small brown spots on certain leaves
Some leaves are showing small brown spots. Around 5% leaves affected and all are close to each other. Can this be an infection? Otherwise plant looks healthy
