Nute Burn? Can anyone confirm for me?

Hey All,

So i'm about 4 weeks into flowering and I'm starting to see spotting on a good amount of leaves on my table. It isn't all of them but enough that I'm concerned. I've been following a nutrient schedule I found online using the GH Flora series ...

I took a couple pics (sorry for the poor quality, its impossible to take a good pic when the light is on) ... Can anyone confirm this is nutrient burn? For now, I added nutrient free water to try to decrease the strength of the nutes and hoping to see if that makes a difference. In the meantime, can any more experienced growers take a look and let me know what you think?

As always, thanks!Pic 1.jpegpic2.PNG

take pic with HIDs off
 
Definitely overnuted.
Also looks like you might have bugs ( The spots on leaves )...check for spider mites.and / or thrips.
 
kindda hard to say with the yellowing effect of your hps. do you foliar feed? your lights can cause leaf burn from the water droplets. are you in soil or hydro? it never hurts to flush. definately check for bugs on the underside of leaves.
 
Looks like leaf curling too. Grab a loupe to look for bugs.
There is a Bio insecticide called Met52 EC that will control Aphids , whiteflies , thrips , spider mites and other garden pests.

Take more pics , minus HID.
What is your feeding routine and water ?

I'm currently flooding my table twice a day ... I'm in my 5th week of flowering and I'm using 2.5 ml / gallon of Grow, 7 ml / gallon of micro, and 18 ml per gallon of bloom (GH Flora Series)... I have included more pictures with my HIDs turned off as well as a couple of pics of healthy plants on the same table with no signs of trouble... Thanks for all the feedback!image1.jpeg image2.jpeg image3.jpeg image4.jpeg image5.jpeg image6.jpeg image7.jpeg
 
Thought I saw some purp stems , Flowering needs an adjusted ( less ) nitrogen feed.

When you fertilize give the plants time to assimilate the nutrients and use them for growth. Don't feed them every day or several times a week. Allow 6-8 days for cannabis plants to fully show the effect of the fertilization if they are growing on soil. After this period of time you can make an assessment if they require a bit more or not. Cannabis grows best if it is fertilized in small portions rather than receiving a big dosage all at once. Exceptions to this rule are large outdoor plants. They can require high fertilizing amounts depending on their needs, soil quality, and the frequency of fertilizing. But with nutes Less is More.


Is problem grow area wide or to specific plants ?

Its a hydroponic grow, im growing in an ebb and flow table using rockwool. Not sure which plants you saw purple stems but there are a few purple bud strain plants on the table... But id expect those stems to still be green and only have purple buds...

Originally i only saw the issue on a few plants but now i'm seeing it more consistently throughout the canopy... The amount of nitrogen has been reduced each week as I advance into the flowering stage... Im following a regime i found online for the GH nutes im using but im starting to think its just too much. Going to add water every day to lower the nute concentration to see if that helps...
