usually i give Ph'd water every other time. the other times i give nutes. about a quart of water each. 1/4tsp per gal jacks classic orchid special. i usually put half a tsp or so of vinegar into the mix to bring the Ph down to around 6.5. it usually stays around 80-85, no big heat issues

ok so im thinking too much ammonium nitrogen is causing K lockout. is ammonium nitrogen the same as urea nitrogen? cuz thats what i got in my nutes

i am not sure but i think ammonium nitrogen is more available to roots. i do know urea needs to be broken down by micros before the plant can use it
