Help! Somethings wrong!

Hey guys new here and thought I'd start my first post with a call for help.

• Growing in Canna Coco
• Using Canna Coco A and B nutes as per Canna's grow guide.
• 3rd day into flowering of 26 days total.
• Been using CalMag+ as per bottle every watering.
• Plants are fed everyday with nutes and CalMag+
• During veg everything was booming!

Leaves are folding down and the leaf edges are tight, seems to be pulling the leaf down. There is yellowing in the leaves also.

I figured I may have screwed my self with the CalMag+ since I'm using tap water (which I think is hard, I get toilet rings). So prior to this post I did a pretty hefty flush for all my plants with just tap water (nothing else).

Thanks guys!

what is ur PH with your feed water? looks to be a PH problem also check your tap water PH and make sure its around 6.0 usally its high

Water ph is about 7.0 before any nutes.

With nutes is 6.0~ (without CalMag+).


I haven't made a batch with CalMag+ as I think it was the cause of my problems. Not sure which direction of the pH CalMag+ will go.

I think you are right in assuming it was the cal mag+. The spotting on the edges of the leaves looks like nute burn to me. Maybe you just used a little too much. Im not familiar with Cana coco nutes though.

Looks nitrogen deficient to me....

your P.H at 7.0 should be ok

According to Marijuana Garden Saver you need iron, maybe? It says to foliar feed a supplemetn with iron, zinc, and manganese because they are often together. Pics of the pages, I couldn't get a decent pic but it looks similar to me. What do you think? Good luck.

Mine kind of look like that right now and they're running in straight water. I'm picking up NEW nutes today and hopefully a little afternoon snack will bring that green color back. I'll keep you posted on what happens when I give my plants their nutes back because like I said my plants look similar to yours. If it works for me it should work for you right? Ha I hope!

Well after my massive flush I fed the next day and things were looking better. But now I think it's going bad again...

Maybe I shouldn't feed nutes everyday with my water. Should I be feeding nutes every other day when growing in Coco?

it looks like N to me.. but it could be ph also.. try and get your ph down to 6.5 or so ..

Does N deficiency start at the leaf tip or the leaf edges?

And does anyone have a good pic on nute burn?

Thanks!
