Hi All,
I just wrote an entire post, very long and detailed, and then clicked the close-tab button on Firefox. Damn!
Anyway, I have some problems with my seedlings. At two weeks post-germination, they suddenly went bad: huge bottom leaves (unusual in itself), that got a bit yellow and started getting droopy but not limp. (So, it wasn't under-watering, which produces limp droop).
I think I went too high on the nutes too fast. Maybe 500ppm at ten days after they sprouted. So, about four days ago I went back to distilled water, to see if that's what happened.
Well, new growth started at the top, and produced weird looking three-week-old plants. Take a look:
I've been monitoring temp (75), humidity (40%), light (300 watts of CFL's of varying color temps in a 2'x4' grow tent, with each plant receiving about 1.5k foot candles) and PH (5.5). No CO2 yet. No pumps yet for the drip system they're in; I manually water them for the first three weeks or so.
I've read many books, plus gone through three grows, but there's vagueness when it comes to the germination/seedling/early veg stages. The books and research sources often don't specify how they determine the age of plant (from germ? from sprouting? or, like Cervantes seems to indicate, from about two weeks after germination).
There's also vagueness in the nutrient level suggestions: there's a lot of "go light with nutes" as opposed to suggesting specific PPM numbers.
I went back to purified/distilled water about four days ago, and the new growth seems pretty good. But am I missing something that might be the real cause?
Are Original Blueberry strains finicky? Is there one nutrient that might have done this?
TIA in advance for anyone with a "veteran's eye" who might see what I can't!!!
