I havent watered them since sunday so thats about 4 days. they looked good before the watering all though the minute i watered them all and put them back in the tent i noticed there alll dropping down. ph is at like 6.8. is this a bad sign?
Put you finger in the dirt up to the second knuckle and see if it is moist. If it is dry no moister then pick up the plant and see how heavy it is. Now that you know what your plant feels like dry water it.
If the plant soil is moist you may be over watering it, or you have hard water. IF you have hard water a 1/4 tsp Epsom salt per gallon.
As for PH, most good soils you do
NOT have to pre-ph your water. Most soils have a natural buffer and some soil manufactures add a buffer to there soil, like FF does.
