Hey RIU! I need some opinions on this autoflower of mine. About 10-12 days ago, it started to turn a lighter green at the top, and over the past 10-12 days it has progressed to be a pale yellow and has moved down the plant. I know that top down is an immobile nutrient issue, but I am not sure what at this point if it's ph or what.
*Note the QB light makes it appear more yellow than it actually is.
Here is the details of the plant and the last 3 waterings:
-Autoflower current a day before week 8
-Fox Farm Ocean Forrest w/ 35% perlite and amended with dolomite lime
-RH average is 52% and temp average is 78f degrees
-200w QB light board
-Two circulating fans within the tent
I did a soil slurry test with litmus paper and by matching it to the color chart provided best I could, it appeared to read 6.5-6.8ph. I used a metal straw to poke down into the soil in a few places and then used the captured soil in my slurry test. I don't see any bugs, and have thoroughly checked.
Waterings:
6/16 - 4000ml water @ 150ppm & 6.38ph | runoff ppm 750
6/21 - 8000ml water @ 440ppm & 6.35ph | runoff ppm 670 (fed 4ml CalMag, 1ml Tiger Bloom, 3ml Big Bloom, 1tbsp Molasses) *given 4000ml of plain water and then 4000ml of feed water*
6/26 - 4000ml water @ 373ppm & 6.5ph | runoff ppm 510 (fed 3ml Tiger Bloom, 2ml Big Bloom, 1tbsp Molasses)
Earlier this month I had a very high runoff ppm of 3500, so I ran about 12000ml of water through the soil, and then have been easing back into the nutrients for the past couple weeks, hence the lower doses the past two feedings. I had to water today, and honestly I just feel like the plant was very hungry. Idk just the vibe I am getting from it, weird as it sounds I know. I went ahead and fed it again today minus the CalMag (I give CalMag one watering a week if that), just to see if anything changes. I usually stick to water-water-feed with this being the exception.
To compound the leaves changing color, this auto is also on week 8, and very much into flower. So some of these color changes could just be the plant maturing. I am estimating another 2 weeks before it's finished. Starting to see some milky trich heads, but that timeframe is just my guess. Could be 3 weeks, have no clue.
Part of me thinks that by my estimation of 2 weeks of flowering left, I can crash land this girl on the runway so-to-speak. It might be too late to correct anything, but I hold out hope that I can stop it or slow it down. I am just kind of confused at this point.
