New Grower anonamoose's first grow, northern lights auto

[anonamoose]

only just noticed it after watering so cant give nutes for another couple days. 2 leaves are real yellow and obviously dead, and a couple are getting sorta yellow patches. gave qtr strength nutes 2 days ago so i dont think its nitrogen, but im a noob so i dont know wtf im talking about lol. is it calmag? i have some. i remember reading that the rusty lookin shit is calmag lol. thank you. its very faint and cant get it to show up well on a pic but hopefully someone will know what it is.

if it is calmag, i watered literally ten mins ago before i noticed it. would it be ok to give another watering with calmag seein as most of it will be drained anyway?

ph is 6.2 - 6.6

thanks for any help

I wouldn't be too concerned about those bottom two leaves. It's quite common for them to die off. You're pH looks good, but is that the feed or run off pH? Also, what have you been feeding, at what strength and how often? Also, a picture of the whole plant would be helpful as different deficiencies show on different parts of the plant and can be useful in making a proper diagnosis.

Hi,
Could you send picture of the all plant?
From what I can see, the upper parts seems to be well.... for me if it is only the "first leaves" going off as normal past 30 days. They did their job.
But wait for more inputs of others
Good luck with your grow

ph going in is 6.6 and runoff is 6.2 - 6.3. the rest of the plant looks good, however its drooping because i watered recently. cant see any other signs anywhere, its just those 2 really yellow ones and 1 or 2 at the bottom starting to get 'patchy'. i will take some pics now though. i am feeding advanced nutrients jungle juice grow (2-1-6). i fed 4ml/800ml on day 25, plain ph'd water 900ml on day 28, 5ml/1000ml day 31 and today (day 33) plain ph'd water 1200ml. i will take some pics but camera is pretty shit but ill do my best. thanks.

 

[anonamoose]

im sorry the camera is really crap so the pictures suck, but i tried the best i could. the yellowing is only on 2 of the bottom leaves. i hope these pics help. thank you

edit: the 4th picture of the leaf doesnt have the yellow shit goin on, i tried to take a pic of another leaf to show how green n healthy the rest of the plant looks (to me) lol. the last pic of with the leaf has the yellow stuff goin on. thanks

edit#2: its not the first 2 cabbage like leaves that have gone yellow. i mean the 2 that come out when it first sprouts, the ones that arent serrated and dont look like cannabis leaves. they died about a week ago.

Not sure if you can read this.. Looks like maybe Nirtogen and/or sulphur... sry missed where you said only bottom leaves, a lot of times with auto's the bottom leaves will die off a little quicker too . that might be it but im sure you will get more opinions to go by

 

[smith4924]

Are you using R/O water or tap. Cal-mag usually looks more like rust spots then light yelowing

 

[anonamoose]

but the yellowing is spreading up the plant, or so it seems. although the leaves on the stems of the really yellow leaves are fine... its the ones on the stem above that are yellowing

from that list it looks like magnesium or nitrogen or sulphur, but tbh it looks like most of them lol. the leaves are quite dark green everywhere else tho so if anything i think there might be enough or too much nitrogen. aahh i havnt run into any signifficant issues yet i knew i thought everything was going too smoothly lol.

edit: thinkdifferent - im using tesco still water lol. n yeah i thought the rusty stuff was calmag, but i thought the yellowing might be the start of the rust? i have no idea hopefully you guys can help me lol, thanks

 

[Porky]

nvm. - i was wondering about the new growth, but you said its the older leaves.

 

[anonamoose]

just had another look and the yellowing is starting on 4 leaves, not 2! its coming from the bottom up. been reading and i think its either nitrogen or magnesium. would a dose of veg nutes (2-1-6) or calmag plus (also has nitrogen) be better? thanks
