zSkittlez - Only One Left

And yes,... that is sugar leaves turning purp on most of the big flowers. Some of that Grape Ape coming out in it! Days since germination 66 and Day 39 of Flowering, the tops are growing daily if just slightly upwards, they are filling in and fattening up nicely. Frosting starting to get thick on some tops, covering the sugar leaves. Took a look at the root ball, they are still nicely white with no real concerns. Shes got some yellowing going on in the middle and growing upwards, which i dont typically mind, but a little later in the grow (last 2 weeks). She is probably running 7-10 days the way its going, so i either ride it out or water change. I am going to do a full bucket water change with fresh water and nutrients,... very close PH and same temp (keeping in tent all day). Would only get 1/4 yield if this goes wrong, but I will try and make it a low risk gamble. Need to try and keep this plant online as long as possible as the sole yielder. *************** Total Bucket change completed on Day 67/41 ..... went from 5.78 to 5.82 on the PH scale, and started light on the nutes (1083 vs 1880); This will be do or die!! Next morning results.... PH moving up after overnight, about a half a point, but enough to make me push it back down to range. Hoping to stabilize in the next 24 hours or this will get ugly for the plant. *************** Midweek update on Day 70/43 ... we are 48 hours post bucket change and things are stabilizing. Adding nearly a liter/day keeping the water topped, slight ph drift downward but bringing it back to range at dusk/dawn and variances have tightened down to 5.65 - 5.9 and should close more in the following days. For the results, NO Negative signs post change, however we still are dealing with some yellowing. There are a few leaves with spots indicating magnesium deficiency, which i may re-add the CalMag which i left out on the change over. So a little less then 3 weeks to finish, my earlier prediction of 7-10 days early says we may have 10-days to 2 weeks left.... target would be 90 days, we are at day 70. Yield.... right, thats why we do this. She has 3 major cola sites and 8 minor branch cola sites, eyeball says we will likely end with right around 2 ounces of dried/cured top shelf flower from this plant, along with probably .75 oz of popcorn/shake type materials, which i usually infuse in some sort of oil and use in edibles.
