Hi guys,
I have a Female Seeds C99 currently at Week 7 of 12/12. I was feeding 1.5ml of Bloom gradually working my way up to 3ml Bloom since Week 3 of 12/12. Before that it was around 2.5ml of Grow for the first 2-3 weeks of 12/12 as I have seen other growers here do it and it helps keep the plant green longer. This is my 2nd grow using the 'new' more liquid PM OT Bloom, and the 2nd time I've experienced rapid yellowing since around Week 5 of 12/12, so I'm guessing it's the new formula which others have had problems with to according to this thread:

Basically my plant was looking healthy and green until around week 5 when it started getting pale up top. As I would usually do, I upped the feed from 3ml to 4ml and from week 5 onwards the plant hasn't gotten any better, in fact it's looking worse.
My setup is as follows:
250w HPS + Euro reflector
5" RVK
5 litre pots with Canna Terra Pro soil
PM Magic OT Grow wand Bloom
Rootzone Temps are 22-24 lights on, 21-23 lights off
I think I have at least 2/3 weeks before chop, but I wanted to ask the experienced growers here what they would do at this stage.
My aim is to avoid crusty burnt brown bud leaves as you sometimes end up with, I just want the plant to be in decent shape until chop day. And what have I done wrong? Has anyone managed to suss out this OT Bloom issue, have I overfed? I haven't bothered to post this in the Plant Magic section because after about a year of this problem I've yet to see anyone from Plant Magic come on here and acknowledge there's an issue, or to revise their feeding schedule according to the new formula. It's a shame as I used to have blinding results with PM, but now I'm not so confident in this product anymore.
Here is the plant which was topped and trained (quite poorly) and is only about 5 inches or so from the bulb, so I may have bleaching also.
