So far, so good. The Dr amazingly grows similar sized buds above the light level as she grows buds behind the lights. Buds are small in general.
I fertigate her once a day, 0.4 g/L of the base fertilizer. Inflow conc is 550 ppm (ca,. 1100 uS/cm), and I think I may be slightly underfertilizing. I plan to raise the concentration 150 ppm within two weeks and see if she tolerates that amount.
What's fantastic in these long flowering strains, that it seems one has all the time in the world to plan and make changes, in the end, there's so much time to recuperate in case of an inconvenience!
Day 107 (29-12) It consoles me that even the infortunate grow disadventures of mine with this "stretchy sativa" I think the journey will turn out successful. Let's some in April! (perhaps somewhat earlier, I dunno)
If not for yields, which I reckon thwy may not be as large as I wanted (if for big yield was the original intention of growing this strain I wouldn't grow this one specially -which is know not ot be a big yielder, it was the desire of the experience of growing this noble and beautiful landrace (heirloom) sativa. by myslef...and I have 4 more seeds ;)
I raised EC with 0.5 g/L Bloom fertilizer per liter solution, keeping all the other ingredients constant, in concentration and order of mixing.
Every day I have the extra work of inspecting the colas to see whether they are being damaged by heat and eventually apart them from the cobs, etc., but in general, I thank God this could have been even much worse. Luckily she resists both the high indoor temperatures (31 ºC by this date, when outside temperatures are of that order), and pro-silicate additive may have been useful to resist heat, as Grotek claims.
