2 week old plant with leaf issue

[Bozo]

You just explained why you have spots 24 hr of a ph of 6.5 has show spots on lower leaves these spots usaly move up to affect new growth if not corrected quickly
I still belive that flora nova grow would be better than flora nova bloom at this stage of there development

I guess I wasnt clear. I meant once a new res was installed that came to 6.5pH (a matter of minutes) I would pH down to the high 5 range. I hold pretty steady in the 5.9 range. Its not any sort of extended period. Not sure where you got the 24 hour part from? Anyway thanks for your thought tho!

I meant it only take 24 hrs to show Ph problems under alot of light
good luck I'm sure you will figure it out

Actually I saw improvement today/tonite after my pH got to 6.0. All the plants perked up noticably. Maybe there was some absorption issue since I have kept the res pretty steady at 5.7 to 5.9? Im still pulling that plant and installing in my infirmary aero but all the other plants responded to the higher pH.

Glad you worked it out I like my ph around 6.0 also I start it @5.6 and let it drift up to 6 before i adjust it back alittle

Just to follow-up.

The plant had been removed, thoroughly flushed, and treated with a low nute solution (with no supplements). It continued downhill and has been sent to meet its maker. It was just a suicidal plant. It happens sometimes

thoroughly flushed, and treated with a low nute solution

well, if a starving plant receives a treatment like that, what would you expect?
Remember, in your other thread you mentioned it used to be the fastest growing plant before it ran out of nutes

I should have included that it kept going downhill even after the system was flushed with Clearex and the ppms upped to 600+ for a few days. It wasnt starving.
