Thanks Canna, just wanted to share that one, I don't have a lot of 420 time lately, but had to pass that one along. Thanks for dropping in DP, always good to see you online my friend. I use the Fox Farm trio, so using the grow big at this stage, but the yellowing has not spread since I bumped up the nutes before. Let me get a few pics uploaded, so you can really see the new growth, they are growing kind of slow, because I don't have as many watts as I could have in there. This is by choice, because my deadline has moved up, and I'm waiting on the post to bring me a dual spectrum bulb! Anyway, as promised, here's some pics of the plants, which are all doing pretty well, and still growing quite a bit, despite the reduced wattage. Here's the AK47 X UK Cherry Cheese X Skunk#1 which seems to be a very stable cross.
Here's the GDP X Purple Cheese, which had yellowing leaves very early, so it's quite the nute hog, but no new yellowing.
Then the Purple Paralysis, which also had some yellowing, as well as a slight magnesium def, but it's doing great now.
So that's day 42 for the AK X, and the Purple Paralysis, and day 30 for the GDP X Purple Cheese, which continues to be a very slow growing plant. My wife and I made some butter the other day, the old fashioned way, sans machine, and it's pretty good stuff! We used 1 gram of kief for 1/2 a pound of butter, and it's not as strong as I would like, but 3 cookies gets you pretty damn baked!
