First grow: 'Wendy' White Widow (Auto)

Oct 17 (day 57): Start of week 9. She's grown and stretched so much last week that she has got all bushy again. Quite a few flowers which are blocked by leaves and the canopy is different heights again. Performed some LST and a fair bit of defoliation to open her out. She responded really well and when I checked on her in the evening, she had already repointed towards the light and was adjusting to the LST. Fed her with 2L of water and week 5 of the nute schedule. Oct 18 (day 58): Still responding well to the LST yesterday and the canopy is evening out. She's looking good and the flowers are getting bigger. Oct 19 (day 59): Arghhhh, I have browning pistils again (her sister Ophelia had them too). It's on a lot of the flowers too. Its been suggested that is nute overload, but then I have no other signs of that on any leaf tips etc. I also read that its normal for them to brown off after a few weeks and for new ones to grow in their place. Other forums say that it can literally be a variety of reasons as to why they occur. Where is Scooby Doo and the crew when you need them!? Confusion level: 9/10 😰 Oct 20 (day 60): Looking good, continuing to stretch in places and getting fuller all over. Canopy is fairly even. Older flowers have trichomes now and much darker leaves around them. As always I'm worrying......does this meant that they were being overfed?? Oct 21 (day 61): Looking good, getting fuller and overall canopy is getting higher. Its not hugely even, but I don't want to do more LST or defoliation at this stage. Leaving them to even out on their own. Oct 22 (day 62): I have spotted a leaf peering out from the top canopy which has brown spots. I have looked it up in my favourite article which is the guide by Dutch Passion. Brown spots point to a calcium deficiency by the looks of it and the photo in the article shows a leaf just like this one. I had laid off the calmag since week 5 as my email from BioBizz said I wouldn't need it unless the water was soft. The challenge with organic growing is that you see issues days (sometimes weeks) after they happened. I guess cutting the calmag out was a mistake and I should have kept it going as a preventative measure. However, I don't think I can blame myself for taking the advice on an email FROM THE NUTRIENT MANUFACTURER!?!? As always, there is NO substitute for actual personal experience. Here is a link to the article I referred to: https://dutch-passion.com/en/blog/a-visual-guide-to-cannabis-deficiencies-n987. Fed her with 2L of water and week 6 of the nute schedule and 1.2ml of calmag for deficiency correction. Frustration level 9/10 😤 Oct 23 (day 63): End of week 9. Lots of small surges of growth from the lower branches and the overall canopy is a good 2 inches higher than the start of the week. Smaller flowers getting much bigger. All in all a challenging week. NOTE: Nutrient amount is the total amount of nutes given during the week.
