Acid soil causing calcium def. so I fed it milk.

Just kidding about the milk.

Strain: Blue Mystic
Medium: Fox Farm Ocean Forest (was at 6.3 - 6.8 PH when started). No added perlite or other substance.
Phase: Two weeks into flower, vegged for a month
Fert: Nothing for veg, and haven't start Fox Farm Big bloom due to acidic soil.
Water Supply: City water, left out for 24 hours, ph is always 6.5-6.7
Pot size: 1.5 Gallon

Problem: Shame on me for not checking the PH of my soil runoff more often. Everything was looking so good until I noticed obvious signs of Calcium def. I checked the soil run off and to my surprise the PH was hovering around 4!! I almost crapped and decided to buy some "PH up" from the local pet store. I wanted to bring up the PH slowly so I flushed it with PH 8 water twice a week. The soil PH won't raise above 5 using this method. I flushed with PH over 9 water and still the run off is at 5. It is crazy. Any suggestions on how to quickly get my soil up to 6.8? It has been between 4-5 PH for the past two weeks and I am starting to see other nutrient lock outs?!!? Help me my brothers and sisters!

I feel your pain dude, I lost half my fan leaves due to ph problem and soil being under 6. Trying to bring the ph back into range with a higher ph water wont do the trick, you gotto get some lime and work it into the top soil as well to make the soil sweeter. I bought some today and applied it, Ill see how it goes. I got the hydrated lime because I need the change to happen now and not later due to being a month into flowering. Good luck keep me posted on your method and outcome.
Thanks

grind up some eggshells and sprinkle them on the top soil, that might help. or maybe some baking soda on the topsoil ??

Hey these are good thoughts. The lime will also help my calcium problem + raise PH. I wonder if you can foliar feed with lime? The egg shells will also provide calcium and increase ph according to iastate.edu agro tests. I watered my girls again today with high PH water (9.5 PH) and the run off is at 6 on both plants! I think I will lay off of the "PH up" water mix and add a little lime + egg shells to the top soil. I am also going to investigate foliar feeding with lime to hopefully provide a quick fix to my calcium def. This site is great! I will update you with the results.

i LOL'd when i read the title...

just remember u might stress your plants by running high or low ph'd water thru your pots.
