Hi to all and thanks for all the help that i have got in here. my problem is that after day 60 to 65 from seed i notice yellowing of the bottom leaves that moves upwards. in organic grows and non organic grows . what can i do to counter it? could you please advise me ?
in the liquid fertilizer grows i imagine i need to increase the flora nute but im not sure. on the organic ones what do i do ? i tried to topdress with bat guano and also make bat guano tea but i didnt notice anything. the yellowing keeps coming up. i also thought to up the N but i dont know if this will hurt the bud development. maybe this is natural since the harvest is near? im first time grower can you please advice? thank you. tried to make a foto of this but it comes out more green than it actually is. i hope you understand what i mean

yes thats it . will give it a try and report
This stuff right? https://amzn.to/2Ap50ug
Never heard of it. Looks like the ingredients are magnesium nitrate and calcium nitrate.
have you heard of the advanced nutrients "revive" ? if yes can you explain what it does? cant understand the mechanics yet . would trhat be something usefull for problematic plants?
goodmorning . yes unfortunatelly thats the runoff ph. the first pic is the organic and the second is organic but with liquid nutes (advanced nutrients) . cause of ignorance i flushed them both 2-3 weeks ago cause of high ppms and from that moment i lost the soil ph regulator that biobizz light / all mix has and from that moment even if i water all the time with 6.0 ph i never managed to bring it down to 6-7 range :( .
visited a garden shop the other day and the guy proposed that i use a much lower ph fertilizer of 4.5 ph with the watering but since im like 20 days from harvest i dont want to risk doing stuff.
yes from the link you gave me i think thats it . the problem is that i cant even foliar spray with so many buds.
any propositions?
That's the runoff pH? Very strange that it drifts so high. That could be why you're seeing issues. What type of soil are you using? You mention one is organic and one is not. Which one is which?
Looking at your pics one more time, do you think it may be magnesium deficiency? Link to pic of what it looks like: https://www.mrgrowit.com/post/2017/11/14/magnesium-deficiency-in-cannabis-plants
the bottom one gave me 7.5 ph and 2000ppm and the first one gave 7.2 ph and 1200ppm . is the reason the outdoors? i have been feeding ph 6.1 for the past 2 weeks but the soil keeps the 7.2-7.5 ph.
Ah outdoor plant. Ok. Hmmm. Do you know what the PPM is in the medium? Most check by doing a runoff test. That will give you an idea of how much nutrients are in the medium.
my phone camera puts more color for some reason at this time of the day . im posting below 2 fotos of 2 different plants. i also woulod like to thank you for what you are doing . and im saying that and i mean that . beeing first timer is amazing to have ppl to help you like you do. thank you again
thats the 1
and
also you are right that the leaves that i see yellowing are mostly the ones hidden from the sun . the first one is day 53 and the bottom 65
Can you show us a picture of the plant? You mention they are bottom leaves; often times the leaves that don't receive light will die off. May just be that. The pic of the leaves here don't seem like much yellowing at all.
