So finally got my first grow going here in raining San Diego, been referencing the forum for guidance, but I think I need to reach out and find out what I’m totally blowing and what maybe I’m doing okay on. Specifics and photos below of my grow so far.
Questions:
I bought Cal/Mag cause I keep hearing people talking about it. Can anyone tell me if I should be using it, when, and how much? It doesn’t show up on the FF soil feeding schedule?
When should I manicure these girls? Feels like maybe too soon?
Is my EC run off being so high a problem?
Trellis is up, but I’m not what I’m doing with it…Do I need it?
What else should I be asking?
Gotta say this forum has been amaze balls! Any comments welcome. Overall I feel pretty good, but if I only knew what I don’t know Thanks for looking and helping me!

I love fast forward posts. Cal mag is used when you have a lot of light, and cannabis is generally hungry for both.
I wouldn’t be too concerned with the run off numbers, FFOF has a lot of nutrients in it.
Otherwise looks like you’re doing fine.
Ya I was just too busy to start a grow journal on my first run. I feel like I’m about halfway to harvest so maybe I’ll do a second half “fast forward”. For the Cal/Mag question I’m not sure if I have a lot of light or not. I have (3) 260 XL respec…so not sure if I should incorporate a preventative Cal/Mag regiment or just wait to see if a Cal/Mag deficiency show up.
5 ml/gallon cal mag under those lights: you can just go ahead and assume you’ve got a lot of light haha. Those will make the plants cal mag hungry. It won’t hurt to dose em. I do it at water days but you can dump it all in with the other nutes if you want.
I agree. When you have that much light, unless you see the plants get nutrient burn, you’re not feeding them too much. For example, I finally ended up adding 25% worm castings to FFOF. That soil is already pretty hot. And I finally have a decent grow that’s not showing deficiencies left and right. I’ve also thrown the canna nutrient line schedule out the window. Max dosage, and then some.
If that’s the only supplement; every other watering? I don’t know your nutrient schedule (if any) so hard to say. I’m in coco now and do cal mag with every watering as opposed to feeding.
soil soil? Or supersoil? Or fox farms soil? What are you using ? Like I know this is an old post? Just scanning around. Anyways, what are you growing your weed in?
