Okay, it's Tuedsay and time for an update.
It's day 22 of flower, the start of week 4.
Alice is stretching just a little, which is making her build recognizable colas.
I have noticed that her new growth is a healthy dark green at the bases of young leaves ... but it yellows toward the tips. That, and she's been dropping leaves at the low-to-mid level. I took over 20 leaves off her in the last two days.
I've interpreted this as appetite, specifically for Mg and N. GH Flora is somewhat low in Mg, and I did not take the elementary precaution of adding dolomite lime to my Happy Frog soil. So now I have to provide total nutrition, effectively "soilponics", into the awesome felted puck of roots that the soil has become.
Here's Alice's canopy ... the very dark green of her youth isn't there any more, except close in on new growth. Nitrogen!!
Here is a bud close-up. Some trichome formation is evident, and the side buds are growing reasonably well.
A backlit sea of adolescent colas. PedoBud.
Bud and leaf structure from below. Kind of airy, but I suspect she's not even halfway there yet.
So I decided to give her a shock of N and Mg. Since she's flowering, i didn't want to stint her on P either, so I weighed out
ammonium nitrate 2 g (350 ppm N)
magnesium sulfate 2 g (100 ppm Mg) (130 ppm S)
monopotassium phosphate 960 mg (110 ppm P) (134 ppm K)
and dissolved them in 2 liters RO water for a final TDS of 1330 ppm. I had to swirl hard after adding the phosphate ... I got some mild clouding (most likely from the formation of struvite. This is ammonium magnesium phosphate, a poorly soluble salt responsible for a common sort of bladderstone) that cleared up quickly.
I fed this to Alice, who was still pretty "heavy" from the GH Flora feed of two days ago ... but she took the whole gulp without any overflow. After her short spa session in the sunlit window, it was back under the Ushio with her.
She is a vigorous enough plant, but she smells lousy ... a sharp green/metallic scent, and sometimes I get the distinct and specific smell from her buds of freshly-cut schedule-40 white ABS pipe. NOT a top-shelf smell. But I have noticed both plants evolving their odors in different directions as a grow progresses. So I still hold hope for this one ... yet I don't feel bad about challenging her with aggressive nute combos. After all ... this is for science!
