Past PK 4-8 issues.

**Kurdt** · 04-07-19, 11:46 AM

Pretty much all my previous grows i used the OT range including the pk 4-8 and ive always had issues with rapid leaf rusting/yellowing/dying etc in flower. The buds have always come out ok though but the plants themselves have ended up looking like something out of the walking dead! Anyways, im sure I read on here somewhere that someone said that auto's really dont like the bloom/bud boosters? My current grow, all ive used is the organicus 99 and apart from the usual yellowing of the bottom leaves, ive had no issues at all, plant is doing great and looks healthy. Anyone else noticed this?

Many years since I used soil but I had no issue with organic PK boost.

Ive used the pk 4-8 and I only feed once a week
Tried twice a week before and my plants hated it
Going to give the pk 9-18 a nudge

I use PK 4/8 no problems whatsoever.

This is the only grow for awhile where i havnt used it, all conditions are the same otherwise,ie, same soil,temps,watering schedule etc... Just weird. It's bugged me for ages why the leaves have always gone fubar with my previous grows, its the only thing i can narrow it down to.

just a thought Kurdt are you in a hard water area? To much calcium and K together can have adverse affects on your plants .

I did think that initially but the water is considered moderately soft where i am.

The main reasons for the yellowish appearance of plants are not enough water and light, are you sure all your leaves are getting enough light?

Yeah, defo getting enough light and water. Problem is, they're not just yellowing, they get rust spots, shrivel and die. Thought it was a cal-mag issue so have tried giving them that but never stopped the issue. With my current grow, havnt given it pk 4-8 and have had no problems, just trying to do a 'process of elimination' and so far,thats the only thing that's flagged up.
