It seems i dont have AN nutes dialled in yet (no shit huh :D ). I would need some advice/second opinion on the def i am seeing. I presume it all started cause of overfeeding (havent done everyday feedings before), so stopped the basenutes and gave additives for 5-6 days. And now i think i have a mild K deficiency.
Gave her yesterday 1.3 EC with base nutes, ph is fixed by AN to 6.0 or so.
But hey, let the guessing begin :)

Who can sport the problem, bagfull of vape from me! :bighug:

Yea if its down there that would be my guess too. You testing ph? If its in range then it might just be a little too much nitrogen causing the k def
 
Yeah, i always measure the pH and EC. Since AN has the "pH perfect" system and the pH is usually 5.8-6.2 (locked by AN) then i have fed them like that. When i asked them (AN) how will the pH work on soil where the pH should be higher they told me that cause of the chelates the nutes are absorbed on wider spectrum of pH.

So yeah, yesterday i fed them with EC 1.2-1.3 and pH 6.2

And i definitely agree on the N problem, i think i messed up by giving too much (tried a feeding schedule that was recommended) Cal-Mg which contains considerable amount of N too. So the EC was 1.8 too soon. Maybe N accumulated. I did not feed them with base nutes for 6 days (until some necrotic spots were seen), so no additional NPK. EC was like 0.5 or so.

Then started to see the necrotic spots which looked like K and since i havent fed them per se for a week the only logical conclusion was that is K def.
 
Well knowing what went wrong is always good. Maybe pick up a different brand of cal mag thats lower in N i use plant magic magnecal and have had no problems so far
 
i will keep feeding them little by little (EC max 1.2) and let them be until the end of this week. If problems are still present i will consider flushing them, since i have ca 30-45 days to go.
