Ph to low ? Help !!

Hello all this is my first grow ...

NYC SD..under 400w MH
Fox farm oceanic
bat guano
worm castings
perlite
fox farm grow big
Temp 77
Humidity 43%

Just transplanted 4-5 days ago getting ready to move to flower room, and now this !!! Any quick fixes ???

24 views and no one knows ....Plz help

Now its starting to move around the plant !!!!! 6-7 leaves

Need more info.........could be ph probably too high, not low......could be nute burn, could be a mag deficiency. What are your numbers, you really need a nute & ph meter.

Just checked PH at 5.7-5.8

Going to pick-up a nute meter today ..anyone got any suggestions on a good one ?

170$$$ Fuuuck that ...and if i had a nute meter what would i be asking you folks for ? lol

Anyone else ?!?!?!

Watered with H2O + hydrated lime last night and PH today is 6.3-6.4, but looks like growth has stoped.
