Ok so the issue here is the plant "hardened off" a few months ago and it got nutes and a nice sized pot, a few weeks after the nutes and repotting the plant was looking very healthy and had very nice big flat great leaves, and none of the leaves were twisted, none had leaf tips that were browning with the typical "salvia dead tip" and none of the new growth browned and or randomly died off like before(random browning leaves would end up fully browning an falling of normally quarter size if they made it past quarter sized it wouldn't die off).

Now a month after that^, the leaves are starting to get "dead tip" and twisting.... No yellowing but all of the past problems are back and can't figure out why it seems to almost be a cycle but that may be pure speculation ...

Soil- perlite, verm, peat. 2:1:1 ratio
Water- distiller w/ cal-mag ph of 6.6-7.0
Nutes- once ever seven days, just two part from GH ph of 6.6-7.0
Light - 125w direct about 7-13"away, 16-8 photoperiod

Any advice or opinion on the issue at hand would be awesome !!!
