Defincency

[dtracy11191978]

What do you think is wrong with this plant?

 

[Rurumo]

Typically taco leaves like that are due to heat stress, what kind of temps are you seeing in there?

 

[HydoDan]

Either light or heat stress..

Perhaps magnesium deficiency considering the purpling stems. I have a stand-alone dwc bin with 6or7 strains and only one clone showed similar cupping of the leaves. Heat and light stress definitely wasn’t an issue in this setup. Researching I came across possibly a mag deficiency. Sprayed with Epsom and it resolved... good luck

Either light or heat stress..

The highest it went was 80F

Here a better pic. My other plant is right next to it and is not showing any deficiencies.

Can it be ready for nutes? I have not started any nutes. It's in straight compost with perlite mix.

What kind of compost as that 'deficiency' looks more like high N causing nute burn to me. As it only seems like it's happening to leaves with good light exposure I suspect a bit of heat stress causing it to happen there alone. those leaves are getting bit too warm so draw extra water and nutrients into them to cool themselves down. Those extra nutes build in the leaf tissue along the margins leading to the curling and yellowing, (soon to be browning). Kind of like localized toxic salts buildup.

How high is your light hanging from the plant?

 

[dtracy11191978]

How high is your light hanging from the plant?

It's about 16 inches from the top of the plant. The light is a bloom plus 1000. It's only about a true 100 watt.

It's compost from my backyard. Cut grass clippings and brown leaves mix.

That's "sub-optimal" to be generous

How old is the compost?

 

[dtracy11191978]

How old is the compost?

About 6 months old.

I thought it would be good to grow in because they call it gardeners gold.

About 6 months old.

I grew successfully in compost. But I gave it two full years to age. This supports the “too much N” hypothesis.

Nutes my man Nutes.

 

[dtracy11191978]

Then that may be my issue. Thanks. The compost is 6 to 12 months old. Right in between there. I'm on day 33. If there was to much N then my seedlings would have died. I don't get it.

Day 33 of my grow.

Should I start adding nutes?
