I just pulled that leaf off to try to get a pic. I will update later. It looks like the leaf is fine other than just being a bit too yellow for that stage of growth.you should take some pics without the hps lights on for us,a whole plant pic might be helpfull also,not just a dead yellow leaf :) and maybe give some enviro # for us as well.peace
Yeah im not trying to be an ass,it just looks yellow and dead on my pc[/QUOTE
Gold Label Coco. Heavy 16 full line. 3 gallon smart pots. I believe when i was normally feeding i flushed and left the medium no nutrients so the plants would yellow.What type of medium, pot size, and nutrients are you using may I ask? Also if it's towards the end of flower it's going to start yellowing.
Throughout the plant. Mid and lower.Also is the yellowing in the bottom or the top of your lady(s)?
Week 6. I could just be freaking out for nothing but it seems like they responded well to what we did last night.How far into bloom are you. If your towards the end you should be happy thier yellowing.
Sounds like a ph and silica definitely then, also if your six weeks or so into flower this is just natural.Throughout the plant. Mid and lower.
That's part of your 'problem' right there. Stop flushing with plain water and then getting aggressive again. If you feed low and slow throughout the grow, you won't really need to flush.This is actually an update to a post from yesterday. To refresh I have recently had an issue with yellowing of leaves in flower. I attached the two pictures for reference.
I think it is a problem with the way I flush my coco coir. I have always flushed with staright watet and left my plants for a day instead of following a flush with aggressive nutrients to keep the nutes in the soil and available to the plant at 6.0ph.
Let me know what you think. I will update tonight after I attempted to flush and feed last night.
Thanks
We need to see the whole plant because that is key to deciphering what the problem may be. We need environmental parameters (actual parameters, not statements like "the pH is fine") in order to further help us help you. I'm not saying you did this, but we see many new members come onto the site and say exactly that. What, exactly, is the pH of the root zone, what's the pH of the run-off, what's the pH of the feed/water going in?Haha ok.

That is a classic potassium uptake/utilization problem.Throughout the plant. Mid and lower.
Saying that bro, is it good to keep having to adjust the pH before every feed? By adding more pH up/down essentially arent you adding more nurtients as well? (Big Learning Curve This One!) Ive had some problems with pH fluctuations as well but im in the middle of winter and our tap water is at 7.0... It usually goes up after they feed? Should i give them another flush (its been a week)I would say back off the nutes a little bit and ph your water after all additives. If the problem persists and the flowers are looking fine then don't worry, she knows what she's doing. Then again it could be silica, process of elimination my friend.
