I need some advice. My plants were acid burnt ph of about 5.8 to 6. They were like that for a 7 to 12 days(couldnt get a ph tester) Then I used Baking soda to bring up the ph. I added water with a ph of about 7.4 to 8. Yesterday night. Can anyone help me out with a time frame of how long till they start to get better. Should it be soon? or can it take a few days? I am using a 105 w cpf and 2 4' fluros for the light. I could really use the advice.  hits for ev eryone who helps  | ||

ph of 5.5-6ish should be the target range. acid burn would be ph of 3 or something. ph of 7.4-8 is WAY too high. care to elaborate? peace- arnold layne

| right .. theres definitely something going wrong here .. but before we go straight to pH, lets make it clear what all the other variables are  type of soil, preferted? with what? how old are the seedlings? how often do you water and feed? how much light? temps? RH? pH 6 is a touch on the low side for soil, but best to make sure were not missing anything

| right, i think youre going to have problems adjusting the pH of the medium now that the plants are in there. i think the only real option open is to transplant to a new mix, with the pH in the correct range before planting. the organics forum is probably a good place to read about soil preparation if we dont get someone in here with some suggestions
