When the drop happens is a funtion of:
-initial soil pH
-initial soil lime content
-fertilizer solution pH
-source water hardness
-re-poptting schedule
-pot size

You can add a little more lime, but I would worry about adding TOO much. Instead, potting-up into only slightly larger pots, once every ~5 weeks, and making sure that your nute solution is not too acidic, will make your life easier.

Contrary to popular belief, it is not stressful to anyone but the grower to re=pot in flower
stinkyattic Reviewed by stinkyattic on . How should I apply my lime? Hello , I'm having trouble keeping my soil's (FFOF) PH from dropping, last time my water going in was 8.5 and runoff was 6.5-6.6. So whats the best plan of attack? I've read I can disolve 1 gal of waterand1tbsp of dolimte lime and this should buffer it. is this right? thanks forgot to mention I did not amend my soil with lime. but have learned me lesson!
