I was gonna say dont rip the leaf off, but!!!!! now for the flush 3 times the volume of the pot with air temp. water allow to drain no food for 2-3 weeks, or in this case .....ever!


but you rea;y gotta ask ya self....'does a plant go to harvest with full cover of green leaves? ..'

It's hard to say if its N burn or N def. A pic of the whole plant would help, plus what you have been feeding, how strong and how offten. Also check PH.

to late.. Oops lol. Do you think its nut burn.... Hense the flush? Yeah I am expecting most of the leaves to yellow by harvest... I just wanted to make sure this wasn't a problem that would effect yeild, if untreated?

cheers mate

i have been feeding biobizz bloom, its Npk is 2.0-7-4, i had stopped the biogrow aa couple of weeks back but due to being told i had N def, i have added a small amount of biogrow. My ph is spot on between 6 - 6.5.

It's really hard to say without a pic of your plant. With your PH being spot on, I would say its more likely an N def then burn.

its a bit to difficult. To get a pic of the whole plant right now... Its at the back of the tent and not easy to take out. I may have a pic of it from this morning... I'll check. I cant see any clawing of the leaves on it anwhere, also its not super dark green... It is green but not really dark. I have noticed that its been drinking nearly 2 litres of water a day. I watered yesterday as the pot was so light, when I was altering things today I noticed it was so light again and it took on 2ltrs of water untill I got some run off. Pistils are turning amber quite fast too, yesterday just the tips of a few, now alot more. I. Might have a pic of a bud from yesterday and one I can take now if that helps? Ill look for any pics of that plant now.

cheers

just waiting to borrow my Mrs phone, couple of mins. Might have pics of whole plant from earlier. I'll take another pic of cola so you can see how many pistils have changed in 1 day. I dunno if they normally change that quick.

Everything looks normal from the pic. What week of flowering is she in. Still would help to see a pic of the whole plant. Your yellowing leaves might be just normal flowering loss.

iv beeen loosing them slowly for the past couple of weeks. Ok cool, what makes you say 4 weeks.... The way it looks or you recon push to 12 weeks? I'm not an impatient grower... So 4 more weeks would be good as it gives time to fatten up. U wanna see my other strain in growing? Its red poison. Would like an idea on how far off I am.

your final nutrients should be mid p and high k. no nitrogen or very little... autoflowers need more p than normal strains
