Help please

[Greencheezit]

I'm not really sure what is goin on with my plant I have checked and inspected it for bugs but I havent seen any I'd say this has happened within the last 2 days it was really hot here yesterday it needed watered but I wasnt able to get to it until last night please let me know what you guys think the leaves are curling up and now turning colors

I’m a lil busy at the moment to look into that for you bro! Hopefully someone comes to your rescue here shortly!!

It looks like it might be suffering from heat stress which could cause nutrient lockout.

I'm gonna say Ca/Mg deficiency.

 

[Emilya Green]

since it is in the upper growth it shows as a non-mobile deficiency, therefore it is a calcium deficiency.

That chart shows Ca as a mobile nutrient? You’re saying it’s immobile. I’m inclined to trust you more so than the chart, but why is it immobile on the chart?

 

[Emilya Green]

Probably why you don't see me promoting that chart... Ca deficiencies show up only in the top growth because the plant does not have the ability to take the needed mineral from other areas of the plant. If you are light on Ca, it shows up immediately in the growth that is happening now, at the top. Magnesium is also misclassified by this simple chart, because it is now known to be Semi-mobile... and problems with Mg first show up in the lower leaves, but not exclusively... some of its damage also shows up in the middle to the top of the plant.

 

[ChefDGreen]

@Emilya thats why you’re the authority on the matter and the chart is not!

 

[Bush Doctor 77]

Probably why you don't see me promoting that chart...

I just used the chart to diagnose the Ca/Mg problem. I've never had it, just went to the chart and looked at the pretty pix.

Don't mean to hijack your post but I have a similar curling of leaves on a Northern Light Fem I am DWCing. Before the curl the new leaves were yellowing so I added Cal-Mag. This seemed to help the yellow but then the curl started.

I've backed off the Cal-Mag a little in case there's too much now and raised the lights in case it is a heat issue.

Curled leaves on Northern Lights fem

I'll be watching to see if you problem is resolved and might help mine.

I was also thinking a soil flush with fresh correct PH water could help your ladies thrive a little bit more too.

 

[Greencheezit]

My soil and water is at 6.5 I havent had a chance to go to the grow store but I will be there first thing in the morning I really hope this is a cal mag issue

 

[Greencheezit]

Can anyone say a time frame on how long it takes before it starts really effecting the overall health of the plant ?

Heat stress, some cal mag should get her back on track pretty quick, just dont overwater her

 

[Greencheezit]

Ok it looks worse today still think a cal mag issue?

 

[Greencheezit]

This was the closest thing I could get to organic in a hurry

 

[Commando45]

Give it afew days see if it stops the spreading

 

[Emilya Green]

it is going to take 2 or 3 watering cycles to get the nutrition moving around, and any dead areas now will not repair themselves. All you can do at this point is to stop it from getting worse.

 

[Greencheezit]

Should I cut off the bad stuff ? Or wait a week and see wats up

 

[Emilya Green]

Wait a week... if the plant wants something gone it knows how to sluff it off. If you take it before the plant is done with it, the problem just moves up the trunk to the next set of leaves.
