Whats wrong with my leaves *pics included*

[Friendlytoad]

My plants got a bunch of these leaves with rusty splotches and the plants have been kinda droopy also. Any idea what this is. Copper deficiency?

My first assumption would be calcium deficiency, you’re going to have to give us a little more background and info.

Sure thing. So week 2 of flower. Blackberry auto flowers. Spiderfarmer sf4000.

I'm using promix and have had issues with this soiless stuff. I'm currently switching over to hydro.

I use general hydroponics trio. I do about 2ml micro and grow and 3ml of grow per liter of water. I also add 2ml of calmag per liter. I was ph balancing it to 6.2

I recently read spoiless needs 5.8ph??? So I think I need to change my ph. My temperature is stead 23 Celsius and also humidity is steady 50%

Here some more pictures. They keep getting droopy also and just don't look too healthy overall.

Sorry I meant 3ml of bloom, I also noticed the very tips are kind of twisting?

Now that I think about it. I've been only doing 3ml of calmag per 8 liters. I need to be doing way more than that. Its probably calcium

Could potentially be cal, I just dealt with this on my run. In my experience the leafs were browning and creating small holes. Affecting first old growth and then new. Didn’t look quite like yours.. Droopy was present aswell. Up your cal/mag slightly. I did one third above full recommended. Then once recovered reduce slightly but not back to where you were.

Thanks, I'll up my calmag and hopefully that will keep it at bay. Also I'll make sure .my ph is spot on 5.8

Yes that’s another point I meant to mention, i ph 5.8.
