1st indoor grow:RQS PurpleQueen/Critical

The reason for this odd mixture of nutrients is because of the constatation of a low pH, all the pots have sunk down to a pH level of 5.5-5.7, because of this certain elements like P, Ca en Mg, as well as N in a modest amounts start getting less available in the soil because it binds to other compounds, which the plants can't take in. I wasn't too sure of what return rate the nutrients would have when the pH started increasing again, because i first thought the necrotic spots were signs of too much fertilizer, instead of the low pH, so i watered extensively, which might in turn have rinsed out of lot of these compounds. Seeing that the major deficiencies were P and K, i decided to reintroduce these compounds in the soil. Adding plagron pH plus as a one time addition, will make the soil a bit more alkaline in a shorter time span than normal tap water, i added a modest amount of all of these fertilizers (1/4 to 1/2 of the recommended doses. expect the pH plus) to ensure the plants don't stress too much. The addition of this mixture was on the 9th of febuary.
