This is why I'm so worried! She's a frosty babe and I don't wanna ruin her!!

She looks prime bro, soon you will be in flavor country!

Keep doing what your doing, she'll continue to fatten up as she starts to eat all those leaves up. Good job getting her to this point

@iampepe @fettled6 thank you very much indeed gents, you've put my mind at rest

Yeah, stay the course bro. If you don't have the ability to check ph, I wouldn't do anything to try and adjust it (ie vinegar). You could easily overshoot and have no way of knowing. She's not so beat up, she'll run thru the next couple weeks without incident.

Red stem can be from low temperatures (at night).
I would not worry about "troubles" you have. One leaf is "damaged", plant has 200 leaves more.

Thanks man, appreciate the knowledge

Thanks mate. Only one or two leaves now but I worry about tomorrow and the next day!

No "night" in my tent as lights 24/0 and temps pretty constant 27 degrees. I think. Thermo is broken and I just see "7" on the screen!

You can ask your water company what the pH of your tap water is if you ever worry about it. It may be on their website too. But they look fine so why worry.

Hippy bud-- looks like you drug the party into Sick Bay with you-
...so, fading lowers at this stage is normal, likely you know this, but I know it still makes your butt twitch a little,...... I don't pics of the lowers-?... but guessing it's the typical color fade mainly from N depletion, P can start necrotic symptoms sometimes; color expression on petioles may be normal to the strain, or a co-symptom of P defc, which I don't see sign of on leaves or bud,...color on stems, ditto, but can hint more at a general nutritional lack-of over time,... I see you fed lightly until bloom with AN, mild stuff and low dosages, so perhaps her internal reserves are not well stocked on some elements,...... no sign of Mg defc., spots might be early Ca defc. but generic enough to not be sure,... too few, too non-descript,... however, since your dosage is low, and you're under LED's, the Ca demand is often elevated, so up the Ca-Mg some... what brand is it, and does it have significant N in it? 1-0-0 or close is OK,...4-0-0+ is not,... the color of the leaves says N is not an issue!
I know Dense, a monster K booster, what's the NPK on Bud Booster? ....
..... bigger picture Hippy, your water source,.. tap, RO/Di? ...if tap, do you know the pH and hardness (ppm via TDS)? This goes to the in-pot pH, not that I see trouble there, but monitoring that is the [HASHTAG]#1[/HASHTAG] preventer of problems through a grow, that, and adjusting your pH on inputs,... I understand costs are an issue, but when trouble comes, and you're clueless for needed info on how to fix, it becomes worth every dime,... flushing is NOT the fix-all response, and shouldn't be done unless there's verified good reason to do so,.. this is a big stressor itself on the plant/roots, and done blindly, may make matters worse, not better,... So, at some point, pick up an Accurate 8 soil pH probe, and a pH meter or even a dropper type test kit like for aquariums, with 0.2+/- resolution,...

Ah the master tells it like it is!!


Thanks dude, your explanations and information are massively helpful! Really good to soak up more specific knowledge.
I used AN nutes at half recommended dose (2ml/L) up until flowering and then abruptly changed to around 1ml/L when I changed to flowering additives. Maybe the reduction in N etc was a bit quick and she started eating her own reserves? I tend to clip off any badly affected lowers and do a bit of a lollipop at the same time as the change to flowering nutes, so no highly affected lower fans available for viewing unfortunately!
Calmag is 1.1-0-0 I believe. I soon learned of AN calmag ridiculous N content in my first grow!! I have only been adding 1ml/L since about 4 weeks, so I will up that today. My last run was with Biotabs (and new babies also on tabs) but this was an "ignorance is bliss" grow with the last of my chem nutes and nothing available to measure PH etc. I will try to scrape up enough £ for a PH meter as I still have two more girls using up the VERY last bit of AN chem nutes I have left over.
By the way, bud booster is 0-50-34 or thereabouts! Pretty insane numbers.

So she looks much happier this morning!! I did give her a mild spray of epsom salts as I bought some yesterday for my aching body! Two birds with one stone and all that

Thank you @Waira and everyone else for your help and mental support!! It really does mean the world when people rally round in support of their fellow growers
