What kind of deficiency? What should I do? By the way, they're autos.
What kind of deficiency do I have going on here? I gave a good dose of calmag last night. The first signs were the dark spots on the leaves. Been feeding ff bloom nutes every other day, 1/4 to 1/2 strength. started from the bottom. Leaves turn yellow and then dry up.

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

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.

Autogrowing
Do these look healthy? Thoughts? I'm new to hydro/growing
I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

Ugly leaves
So, guys.. I asked a question here, like 3 days ago, about some leaves. I think I have found out what has happened. Mold ignition, but very few, at the root. Have already medicated. Do you think this is a mold symtomn? Cheers!

The leaves on the upper plant wake up today with a brownish spot. It’s not light burning for sure (ts 1000 dimmer 70% height 50-60cm). Feeding problems? The first two photos are dark brown, the last one is yellowish.
