    Having a new issue with the same young lady now. Her calyxes aren't swelling whatsoever. Only increased resin production and color changing to Orange in the glandular hairs. Basically it's getting to be time to harvest but Anne never fattened up... Wtf? Has anyone seen this before? Why the heck aren't the calyxes swelling as they should be?

    Yo bro I have a new issue now, PLEASE HELP... On the same plant the flowers are ripening, glandular hairs turning orange, buds getting really resinous.... HOWEVER the Calyxes aren't swelling at all. It's like "air bud"... It looks fat but its like 50% air. The Thing that's really strange is that the plant right next to it is in the exact same soil mix, receiving the exact same nutrient solution, enduring the exact same external conditions, and it's calyxes are so swollen it looks like there gonna pop.

    Anyone know what's going on here>? This plant is completely screwed right? Or is there a way to fix this quick?

    lol you quoted me but didn't say anything... Did you mean to say something? Greatly appreciate any help... Here are some photos which were taken today of both of them.
    First 5 are of the one with the issue and the last 5 are of her "sister" who is just fine.. Agitation is pretty high, especially since the one with the issues is the one which was supposed to be the larger harvest of decent buds and the one that's doing well was supposed to be sort of reserve delicatessen so to speak.

    I threw just that one back into veg for like 2weeks. It really wont stress her that much so long as the ph is good. Test it after you flush her at the soil run off. Then if ph is good on the next feeding start her back feeding nutes. To much salt in the soilthats why she's like that. you have to flush before you throw her back on veg for 2 weeks. Then back to 12 and flush. Then bloom nutes.

    I have a problem with my babies and after all the research I did I am inclined to believe it at be an imbalanced ph in conjunction with bottoms fed liquid nutes. I am open to other opinions which is my reason for posting here. Here are two pictures of leaves I trimmed off less than 5 minutes ago.

    That looks to me like it could be a pH issue along with nitrogen deficiency and possibly a need for some cal mag or any combo there of. pH would have to be really far off to lock out nitrogen though. Check the pH and go from there. I've always sucked at diagnosing my exact issue... I do know however that flushing really well then give half strength nutrient mix which is pH of 5.7-5.8 is the fix to almost every issue I've ever had... Just finished one which I couldn't save for my life... Have super fluffy airy garbage now... Smells amazing but is as dense as microwaved marshmallows...


    Ended up with less that 2 zones and it looks like HP

    What’s causing this leaf damage 3642B239-74BC-4F98-B045-789A5E07E4AE.jpeg 3C98B229-3862-4566-BDFE-BEE3CB029719.jpeg

    actually, that looks more like broad mite damage.
    i don't like Neem oil, it stinks, and i'm allergic to it, but it works pretty good.
    i prefer spinosad myself, not only as a foliar spray, but also as a soil drench at half strength.
    one good drench should be enough, but for russet mites i'd spray at least 5 times at 3 day intervals.
    even if i'm wrong and it is thrips, i'd recommend the same treatment
    (also, i think you're overfeeding slightly)

    Thank you. I was afraid of that. I hope I’m able to finish this cycle with spinosad and forbid4f is in the mail for veg. Thanks again for the input much appreciated

    I appreciate the full guide , but i'm still somewhat lost in here and don't know what is causing the issue

    It's quite annoying and stressfull not knowing what you're doing wrong in order to save my babies...

    So i have been growing last year in my closet using CFL's and regular soil and gave them nutrients when in flower stage.

    Now i bought a tent and mars hydro 300 and soil with lava perlites in it wich ive never used before.

    - For watering , i've been watering every 2 days till the soil is dry on top
    i used regular tap water wich might be the problem (i ordered a ph tester online , waiting for arrival).
    - No nutrients have been used yet
    - Veg stage
    - Temperature between 20-23 celcius
    - Soil is organically fertilized with lava perlite in it
    also the fertilizers in it are based on calcium and magnesium
    Soil ph : 6.5
    NPK is 7-7 , 5-8: (1kg/m³ )

    I've never had so much anxiety and stress growing my babies , i hope i can save these asap..
    Can anyone help me diagnose the problem i have in here

    that soil is way too hot for seedlings, its burning them badly. and it still looks pretty heavy, i'd add about 20% more perlite to it, for better drainage. get something like coco to start in, let them get going in that and develop a few roots, then transplant into that soil.

    Wait what do you mean too hot ? i just transplanted them into some universal growing soil to avoid any more damage.. is that good ?

    i mean it has too many nutrients in it, and it's damaging your young plant. if the soil you transplanted into has as many or more nutes in it, same problem. that's why i recommended the coco coir to start plants in, it's inert, no nutes at all, so no chance of burning your seedling

    Hey growers i have one sick plant of 4 in my growroom.Dutch Passion ThinkDifferent has Yellow spots appear on 3-4 top leveas. Plant is in 35 day and in full flower for 6-7 days. Last feeding 0.5ml/l Piranha,Tarantula 1ml/l Iguana juice bloom 1ml/ Big Bud. Im thinking about ph problems but then my runoff is 6.4-6.6. Temp 24-27 rh 40% Gave Cal/mag extra last monday plant is overall healthy and bud formation i good for this stage.Yesterday i fed 4.5 l till runoff apeared 0.7 ml Big bud 1ml Iguana Juice Bloom. Interesting thing is that this plant i 10 day ahead from other 2td that jut now starts to flower. Problems started when i started to give her bloom nutes.
    Any advice is welcomed.
