Well, as it appears an old OG (riddleme) has returned to be the resident guru for us noobs, I have a question or 2.
I have some gals in 6th week of bloom (hydro), top drip feed w/ mix of 60% hydroton, 40" coco.
Change the res. out religiously every week w/ fresh technaflora (recipe 4 success kit) nutes, distilled h20, and ensure it's properly pH'd . However, after the third day after res. switch, the pH starts a drift down to 5.5, and is @ 5.2 by the 4th day. I'm toppin off w/ straight distilled, but that still only gets to 5.5. I then hit w/ some UP. But I'm havin to do this daily for bout 50% of the week. I have to think that all that UP is less than ideal.
Any thoughts???
I took a guess, and tried flushin all pots w/ about a half gallon of straight rainwater in hopes of maybe flushin up some salt build ups or somethin, before I swtiched res. out last night w/ fresh nutes. Let that dry for 3-4 hours, and then commenced reg. drip schedule. Looks good today, but expectin it to slip down in a day or 2.
Lastly, I again I am in 6th week of bloom. I've got 3 diff strains goin. And 2 of the strains pretty much ALL have yellow leaves. I've only done autos before, and everyone said that yellow is gonna happen after 5th week of bloom, just not sure with these reg. photo period gals. One strain is still a nice lush dark green. Nute def, or something else?? Or all good and part of natural life?
(FYI, the ones that are still nice & lush are ak's, the yellow foliage is some north. lights & bub. gum. Blooms are sicky though, not to worried bout that aspect. Just wanna make sure I am gettin 'em evthing i can.
thanks in advance.
