Violet edges of leaves

[HarlemShuffle]

Hello,

My plant propably have Molybdenum deficiency. Its my first cannabis grow and i didnt get much help in other forum so i post here (on more known forum). As far i read it can be caused by low pH but i actually dont have any good pH measure device and i cant afford any earlier than 1-2 weeks. So i must take action without being sure about pH. Waiting 1-2 weeks would damage my plant for sure.

Transplanting plant to new soil mixed with dolomite would fix the problem? Or water plant with some kind of mixture solution?

I doubt its a pH issue because your plants are eating.....in fact it looks burnt. I'd lay of the nutes a bit, prob the bloom nutes because the lite green color shows its not a nitro toxicity.
