reggie outdoor

i started with 2 was my first outside grow and 2nd all together their first 2 months grew great with no problems in their 3rd month they started looking like they needed nitrogen so i started giving them more nitrogen then they looked liked they was needing calcium tried fixing that and then i finaly figured it out after reading a bunch my soil was way to salty cause i was not using sludge hammer to clean them every month i got them cleaned out also got a ppm meter and a ph meter then to and then 1 of them died from tring to save it i guess then month 6 and on i got the only one to make it i suggest any body that wants to start and hasnt grew before get ppm and ph meteres and look up on the internet for nutes made for pot and make sure you have all the items you need ready before a problem happens
