I can't decide if it is infected or nitrogen deficiency - pics attached

Hi all,

Growing white widow autoflower in coco coir, 200 Watt LED light with average ventilation. This has appeared on 3 plants, yet not others who have identical set ups with physical nutrients added and now tempted to add some liquid nutes (old timer brand).

Am I just seeing nitrogen deficiency or are they some how sick? Im really bad at adding the right amount of nutes, I hope it's just that.IMG_2625.JPGIMG_2624.JPG

Any advice on what this is is GREATLY appreciated. Thank you in advance.

oh dear god... i had to google TMV - so basically it can spread across the plants some how and i need to start chopping the poor affected leaves? It came from Royal Queen Seeds who are usually perfect, only some have shown this issue though

It didnt spread to any other and I had them in close proximity and used all the same utensils. I just cut her down much later in veg though.

Btw whats your nutrient line up, ph, and ppm jazz?
[/QUOTE

PH is about 5.5 - 6.0, seems stable (ish), PPM - i admit, not a clue, i know its important though. I have calmag for once a week and NPK grow phase is 5 - 3 - 3 and bloom is 3 - 5 - 4 - both old timer brand.

It has just weirded me out that 3 plants have each randomly shown this but if it doesnt seem to spread then I guess I will just push on and maybe share my story if successful.

Thanks for the replies!

Yes the Ppm is more crucial than the ph Esp in coco imho. For example let see you feed them today with your usual amounts and they add up to 500 ppm. If you dont test the run off or flush feed them. the next time you water the ppms are going to increase! Now your at 1000 ppms and out of range them problems set in.

Also if you let coco dry completely out if also icrease your ppms once you finally do water.

Ill check my run off first its always the first culprit lol

excellent points man i will start to try this, it hasnt happened on some other plants so maybe it is all boiling down to sloppy feeding
