Not its not. I've grown from 6.3 to 7.5 and was fine. All different strains too. Mg likes to be on the slightly acid's side. Plants looks to be lacking pk. So up that. Grow big will work . In flower.
^^^ This. He hit the nail on the head. I've had the same problem due to soil being to acidic. I would transplant them in fresh soil making sure to loosen up and getting rid of all the old soil. Add some lime also.
Adding fertilizer will make your soil acidic. To counter this add some lime and it'll help keep your soil neutral
Make sure you don't keep soil TOO wet as soil needs to dry between watering- ,so plant can suck oxygen to roots n the roots spread out,looking for moist areas etc...!
alot of growing mediums will lose their ph buffering abilities when they dry out just a thought
Oh yeah, I didn't really mean kosher, just meant like copacetic, or cool. Thanks, I'll look into those pH adjustment solutions. Also, I like Vader, and so far the drops test is the bomb. I think I gotta buy a meter though for regular use. I'm freaked out about this pH swinging. My plant went bad quick. Thanks again.
Much appreciation for all the attention everyone has spared.
