Soil ph problem.

[#1cheesebuds]

Three of my indoor plants are having soil ph problem.
Soil is fox farm ocean forest.
2 plants are regular photoperiod. 3ed is an auto that is around 7 weeks flowering.
All plants are showing the same ph problem.
I checked the soils ph with a ph meter and It read 5 on the acid level.

So how do i fix the problem? I recently also watered that i phed to 6.6 which i thought i had been doing all along befor the problem got worse.

So to fix the soil ph problem can i just ph my water to a higher level more Alkaline for the next watering or is there a more faster acting method for correcting the ph level?

Been down this road before, whether it's Sunshine, pro mix or goler gro.

Best thing is to transplant with new soil with a proper ph. Sometimes i go as far as washing the majority of soil off the roots with a garden hose.

If your set with using the soil you have and not transplanting. You could scratch some dolomite lime into the top of the soil. Or mix some lime and water together, water in a couple times and recheck ph.

Triple check calibration on PH meter as well. Likely too late to do much good for the auto at 7 weeks, unless its a 10+ week strain, better off letting it fade out with just PH'd water.

If the soil has become acidified, flush with plain water to remove some of the excess nutrients trapped in the soil. This means potentially having to dump saucers of water or sponge out the tent, but it will help stop what will otherwise progress. Getting it now will allow your plants time to recover before they ripen fully. If you don't flush out the extra, and just water as needed they will still continue to ripen but the taste and potency will be affected by the plant being in a state of decline.

Had the same thing happen with Fox Farm's Strawberry Fields potting soil. Initially thought I needed more Calcium or Nitrogen so I upped my feedings. Big mistake. If I had flushed things would have corrected sooner. In the end the leaves looked like crap but the buds were still great but I know they could've been better. Taught me to test my watering runoff ph once a week to track how acidic things get.

Will adding oyster shell help?

This far along Oyster Shell and Dolomitic Lime can still be worked into the soil, but at week 7 of Flowering, time is ticking and starting to run out for topdressed granular additives to be effective.

The farmers say ag lime takes 3 months to do any good.

May not be far off but pelletized seems to work better than powdered. Have no problem getting plants to grow right away with 4ph native soil and lime. For what it’s worth.

FF... im gunna flush with plain water and see what happens.
