[Average_Guy 5]

Not seen my plant for 3 days, just came to water and it looks horrible... Ive looked online it looks alot like a potassium deficiency or a nitrogen deficiency, i cant decide which one.. any advice would be greatly appreciated ill go to my local grow shop tomorrow It's an autoflower mystery seed 25 days old! thanks in advance for any help scratching my head at this one :/

 

growing in coco 70/30 perlite mix using standard bio series nutrients half dosage for the auto, watering not too heavy when there is roughly half inch - an inch of the top medium dried out. 

 

Struggled to edit the photos, im still learning haha.. Thanks for your time farmers sorry to summon you.

I don't think you're watering enough so the roots aren't growing sufficiently to uptake the nutrients. 

 

Is there any particular reason that you're only giving half the recommended nutrients? Stick with the recommended dosage.

Because its an autoflower they dont need as much and they are sensitive to nutrients half dosage is reccomended everywhere that ive read

[mrrichiet 8,227]

Ah OK, I was assuming you meant half of what was recommended for an auto. 

 

Being at Day 25, I'd still stick with my original view. If you're sure it's getting sufficient nutrients there isn't much else that could be causing deficiencies at this early stage unless your environment is completely out of whack (not enough info about this to be sure, I'm just going on what you've said so far). 

 

e2a: It's lacking N.

Could your roots be a little cold?  An auto should be a fair bit bigger at 25 days.

You really shouldn’t be leaving coco to dry out, your burning ur plants I bet if you checked run off it’d be really high, fix your run off ec and start watering daily and don’t get soil mixed up with coco they’re different. Go check out coco for cannabis, buy the book if you can it’s worth it imo short but packed with very good info, the site has all the info on it but a bit convoluted.
