Im on my fourth grow and decided to start troubleshooting everything and taking a more detailed approach to my growing. I have noticed that no matter what I do to my plants (light, air temp, ect) they seem to take forever to grow and my yields are good, but for the most part small. I cant seem to get my buds to fill in densely. Im only growing 2 plants in a 2'deep x 3.5' wide x 4' tall cabinet with a 150 watt HPS lamp for flowering and 3 "150watt" (23watts) CFL blue spectrum bulbs for vegging. I have tried everything down to PH and so I bought a PH meter. I started testing everything and I see that my tap water is a perfect 7, sometimes like a 6.8, but usualy a 7 right out of the tap. When I add the recommended amount of fertilizer every other watering my water's PH changes to about a 6.7 or so. I noticed that my runoff and soil however have a reading of anywhere from 7.5-8 and I have a good felling that this is what's slowing my growth. My soil is composed of an all purpose soil mixed with additional peralite to help it drain better (i had a problem with water not draining near my last harvest). I know alot of people frown upon alot of the all purpose soils, but I have two plants vegging at the moment and want to know what I can to to get my PH at an optimum level with what I have. I have heard some people say to add more fertilizer but Im scared to over do it and burn my plants, same with lemon juice or urine. Anyone have any suggestions as to what I can to to atleast stabilize and or maintain this PH in my soil? Was I informed correct about the fertilizer or the acidic stuff? Thanx for the help everyone!:thumbsup:
