Ph Water 6.5 in Run Off 4.0

im using pure blend nuts with fox farm ocean forest soil in 3 gallon bags an making my waters ph level with an without nuts 6.5-7.0 . i just noticed my top leaves where getting dried up an crispy with yellow dots on them, so i deceied to flush it with a couple gallons, when i did that i did it all at once with 6.5 ph water. i waited till it was about done draining before getting some run off water to check the ph an it was 4.0 . is this normal? this was its first flush. if not how do i rasie it to the right levels in the soil? an why is it so low when im making my ph 6.5_7.0 for watering?

Used any dolomite lime?

nope ive just being using the soil an the pure blend grow an bloom , everything is 100% orgainc , expt the ph up an down i use to change the level for watering thats not orgianic. it always does thia shit when the plants start to flower. there always perfect through veg but a little after flowering starts i get the ph problems. if i flush the plant with a higher ph every couple weeks will it stablize my ph in the soil to stand at 65-7?

Are you using ocean forest by itself? Is it mixed with anything?

its just ocean forest. it has everything mixed already . coco, bad mil, wood chips, etc . all that shit it doesnt need any fillers. dont confuse it with the frog stuff. im doing a water , feed , feed , water sechulde

i just need to get my ph up in the soil, an ill keep it regulated once thats done, can i do this my doing a ruteen flushing. with pefect ph water? an this is my first ever flush , the plants are about 2 ft tall an the one with the problem is a northen light blue auto , my other two are white widow still in veg an there fine, getting all the same stuff as the others.

I don't think FFOF is a good choice just as it is. It's very dense and at least need to be mixed with perlite, like 1:1. FFOF is hot by itself, best to mix with a hydroponic medium of some sort like coco or peat. You should not need to add any nutrients for a long time, at least until flower. Just MO.

were can i get ground limestone at , im not sure what kind i should get? like the shit famers spread on there fileds in the fall? or some other kind?

dont confuse it with the frog stuff....you mean happy frog that already has some lime mixed in it?

seriously, lime your dirt, I had the same problem with the frog stuff lol

You want DOLOMITE lime.....Home Depot, Lowes ect......go ahead and mix with your FFOF for your next run NOW.
