So I have learned a hard lesson today about Nitrogen, some of my plants were demonstrating growth on the upper nodes, but I noticed it didn't seem as vigorous and strong has it has been, especially since they are in the vegetative stage, so I kinda neglected about looking all the way down, as I could see most, but not all, vegetative growth. Well, it seems all my plants were starting to yellow on the bottom and some were having brown necrosis, so I did a full pull and inspection, all but the two large flowering ak-48's were demonstrating this, especially the photos. The largest photo plant, to which I have been bragging about thus far, has seemed to suffer the most from this and has lost 30% of her lower fan leaves. I have been partially confused on how to read and judge deficiencies, the top part of the one large female that I just mentioned, had really deep and dark leaves, and the bottom was yellowing and dying. STUPID PH PROBLEMS.. So I did a ph flush, as I honestly had no choice, it has been really hard to keep the soilless mix at 6.0. I am letting them recover for a few days before I do a full feeding, or at least that is my intention unless someone suggests otherwise.. really sucks. The auto white russians are either much slower than the ak-48's or I have done something differently inhibiting their growth. All of them were planted at the same time.
Good news is, every plant so far has been female, hurray! Also the largest auto is 34 inches and the second place is now at 30. The 30 inch has much thicker pistol areas though. I guess there is a trade-off.
Please Muddy, or some other pro, give me insight. I hate watching this yellowing happen. Should I feed light or hard?
I have received my new grow light and I have not put it up yet, I am trying to decided lay out and making changes to the intake fan, one 6 inch fan @ 240 cfm may not be enough. I am considering doing one of these ideas:
1. Connect a Y adapter to use the intake to cool off both lights, on separate intake air channels.
2. Exhaust through one light and intake through the one already connected.
3. Connect duct to the other light and connect the other making one long intake air duct, connected to both lights.
Suggestions?
So in other news, 5/6 are now up and out of the rockwool in the propagation tent. As you can see here:
That cord is the the thermostat control.
But you know what's annoying? When you have that damn one seed who wants to be different and not sprout up with everyone else.. women always want to be fashionably late I guess.
Anyone else hate that?
Opinions? How's my driving? Please call 1-800-420-weed ( come to think of it, why don't I register that number lol) and tell me? By which I mean leave a reply here.
