If its just the lower leaves it may be from getting them wet when watering.

Super soil needs activation?
There are plenty of nutrients in my supers soil. However I heard that the problem might be that the soil isnt "activated" is that logical? Thus need to add organic ferts? I am trying this, but I'm sure the super soil has months of nutes in it!

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Too close to light? Nute deficiency?
Yellow leave with brown spots, what is going on? Showed up really in the last 2 days. It got a half strength dose of big bloom every other watering, the light was pretty close about 6-8 inches away. I didn’t check on it for 3 days so it grew a bit and was super dry.

Don't know what's causing
What would be causing this? I think the one pic with the limp leaf may be from intake fan flow. Also this is just on the bottom leaves. Thanks

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Yellow spots on leaves
Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?
