Over watering WILL make any ph problems more apparent so Reaper makes a good point there. Plus he and Stinky are both soil pros and believe me.....I'm NOT!

To check soil runoff.....you had it ....water (measure ph) through top.....measure ph of water coming out the bottom. If the issue is ph/burn/overwater and you get it straightened out the plant should do fine from there.

Bramptony....in a pinch you can use distilled white vinegar to lower ph and baking soda to raise it until you can get to your hydro store. Better than your aquarium adjusters.. :thumbsup:
Weedhound Reviewed by Weedhound on . Yellowing Leaves(I have researched) Ok i have a problem with my plants.The bottom leaves have started turning yellow. I have Top Soil(no ferts).The strain is White Widow.They are under 3 x 40watt daylight CFLs,They are a few inches from the plant. There is a fan blowing on them. To water i use bottled water so the PH should be fine. I have researched a lot and i think most of the time its nute burn. Rating: 5
