    Hey guys,

    So the other day I transplanted from 1 gal pots to 5gal smart pots to get ready for flower. They were in ffof and are now in ff coco loco after transplant. The pictured plant is an ak48 and is about 41 days from breaking soil. After realizing the lack of color yesterday, I added grow big and big bloom along w calmag to my watering. if this will help, how long does it take to fix the deficency? Any input to what deficency this is? Thanks for the help family!

    Looks like a hungry girl. :) She needs some Nitrogen. (Or a slight increase in general base nutrients.) The new soil from transplanting should have been a decent boost but they look pretty big. You mentioned you already upped your feeding so you should be okay, just keep an eye on them. If they still look bad next watering maybe up it by a little again.

    Do you have a way to measure PH and/or PPM?

    Thanks for the quick reply, I was thinking they. were hungry. Basically I went from solo cups of ffof then after 21 days I went into 1 gallon w ffof. So I was only watering , using spring water. Then right before I transplanted into final home of 5 gal they started to lose color. So I gave the nutes at 1/2 strength last feeding. And yes I measure ph ( usually right at 6.7-b.6.8) still need to get a ppm pen

    You look pretty good dude, really.
    They're nice and light green. If only a tiny, tiny bit hungry. You're nearly a perfect green there.
    If you're in ffof, which i assume is soil, i wouldnt ph your water myself. Id get a ph stake and leave it in.
    You can use things like sulphur to lower ph in soil. Just dont use anything green like manure or guano.
    You can use things like gypsum, lime and wood ash etc to raise it aswell.
    I get a tiny yellow in my tops like that if my ph is a bit high.
    But really man, wouldnt worry. Things happen a fair bit slower in soil.
    If it were me, id give it a tiny bit of liquid sulphur in the next watering. Then see if there's an improvement. If you do use some use way less than the bottle states too.
    Its really not bad at all.
    Good luck man

    I disagree on the nitrogen deficiency. Lower leaves usually show more symptoms than upper leaves in that case. Iron deficiency causes interveinal chlorosis like you are seeing here. Iron deficiency is usually caused by a pH problem. What’s your pH? Make sure your pH, temp, RH and all those basics are in line before adding more nutes.

    So I just ordered a ppm meter to keep track of everything but I had a question, I checked the ph of my runoff and it was 5.77. Is that bad for fox farms coco loco? Or just in general I guess? Thanks for the help guys!

    So my ph has been 6.4.. I didn't start adding nutes until right after I noticed the color change. I just checked my run off and it was 5.77. Is that too low? Thanks for the help man!

    A deficiency and/or pH related lockout was my first impressionon seeing those leaves too

    When I zoom into his pics, the inner areas and outer edges of most of the fan leaves look a lighter-greenish-yellow compared to the rest of the green. That plus over a month old and never fed nutrients.. was my reasoning for N-def diagnosis.

    I've never grown coco, (If recall you treat it like hydro and ph in the 5's), so I would bring ph down to 5.8 to 6.2 range. But it's seems within a reasonable range.
    ^(Don't jump on my PH advice without hearing from someone experienced in coco.) :)

    That PH change might just be what you need, and not an increase in nutrients.

    Just give it a good drink with a tiny amount of nutes, and work until a healthy amount of runoff.
    I didnt realise you went soil, into coco. Thats gonna be tough with ocean forrest in the top of the pot.
    My advice would be to drain and flush it really well EVERY feed or water, from here on out.
    Using ph up and down will be fine too.
    The organics in your soil, is going to cause problems in your coir.
    Just keep it to atleast 30% runoff. Ya gotta saturate it everytime, from here on out. Saturate and water/feed less often.
    I like to feed less in coir, so by the time it needs another water or feed, my micros are in that sweet spot.
    Good luck mate.

    Thanks again for the help. Yea I was under the impression that fox farms coco loco was soil mixed w a lot of coco and perlite. I could barely find any info except one person w good outcome. Should have stuck w ocean forest for now.. But I appreciate the help. I need it, i know very little about coco, so I've been reading threads on it till my eyes hurt lol.

    I just talked to fox farms directly and their exact quote was "good question, coco loco is amended soil w coco coir and is to be treated like soil" so she also said no nutes like ocean forest for a couple weeks so idk... :wall: Could it be from transplanting??

    Id say your coco's locking up the cations in your media.
    Thats why i think its important to flush each time, so you can exchange the cations with fresh ones.
    Just think of when our grandmas used to tell us to water less often but really water it through.
    You have to flush it all out of coco, then charge it back up.
    Thats why i say the organics is gonna be hard. Because you cant really give it a good flush, everytime without
    problems like rot occuring.
    You're gonna have a hard time keeping it zen with balance.
    Did they tell you, to use ph up/down? Or to use organics to adjust?
    Good luck

    I've never heard of it before either, but if the manufacturer told you to treat it like soil then I would take their advice and put in 6.5 pH, but not now wait til next watering and put in extra 20% or so, get some run off and then let us know the ph and the PPM
