You think the yellowing is a N2 deficiency/lockout? It seems rather uniform for being a mobile nutrient?? I'm not sure exactly what PH it is available at but I thought the range was rather wide. Just curious to your thoughts. Keep in mind... this comment coming from someone that experiences "alphabet lockout" consistently. Love me that Golden Tiger! Unrelated... How long did your Malawi flower and when are you dropping your Panama??? Looking good sir!
Lol. Alphabet deficiency. I love it.
I usually feel like an inept puppetmaster of my grow, with a hundred strings attached to me. What's more - I'm an inept puppetmaster who is about 1000 miles away at the moment. I will jet back there in a couple days. Hopefully the grow is surviving well without me, as it usually is.
You're right that the yellowing is very evenly spread. I'm pretty sure the it is a combination of things. For the first three weeks or so after I switched to flowering the plants were getting fed a very low ph mix most of the time- in the low 5s. My understanding is that N is locked out below 5.4 or so and I definitely dipped below that during absences- so that at least makes sense. I would bump the ph up again once a week when I visited. Was too rushed to figure out what to do about it at first. Bubblers have helped a lot.
That doesn't explain the yellowing of the non-hydro plants though. I think I must have messed up the feeding levels during the early part of the 12/12 change.
I wasn't sure that the sativas should be getting any more N, and I decided to switch straight to flowering nutes.
The Cheese I'm not sure about at all. Part of me thinks she is just a heavy feeder that has been underfed. And maybe there are other unknown factors...
I don't know how to go about pinning these problems down - at least not without more time physically present at the grow to experiment and observe. Seems like the best I can do is just forge ahead and try to keep my eyes and ears open and hope that I'll learn to manage a hundred puppet strings just by feel. It's worked for me in the past.
By the way, the screwups hardly ever bother me. I kind of expect it. Shit- I'm not even there -so I should expect worse. And I get a laugh out of the dark side of things. I still have some nice plants. All is well (or well enough)
I've been harvesting the Malawi at around 100 days. I think the earliest one was 95 days and the latest was 110.
I almost planted the Panama last week along with a few other seeds to replenish the Hex plants once they start getting harvested. Took the seed packages out and caressed them a little. But then I thought better of it since not around to baby them.
Next week.
I think most folks attribute yellowing in flower to the plant pulling from the leaves to feed the bud growth and see it as a normal natural process. Different strains do this at to various levels.
2cents.
Most of the plants
do look better now that they're getting into late flowering. They've grown into their yellowyness. It's true that I did yellow them up pretty bad early on- but I think I've done ok with them since that rough start.
