Fastbuds Purple Lemonade & White Widow

Hi 420 Family. Start of week 5 and things are looking great. These ladies have exploded... They all seem to be doing well at this point. Only problems that I can identify last week was that the stems (especially the main ones) started to wilt later in the day. They are not soft or limp, they just sort of bend slightly at the tips. I am not sure what is causing it, but about 1-2 hours after watering they seem to be fine again. I have taken off some of the larger lower leaves, like 3-4 per plant; during this process I snipped one of the main cola's mini side branches by accident... She seems to be doing okay tho. They are also starting to smell at this point and it gets a little more intense by the day. Smell is very sweet and earthy, so quite pleasant. On day 27 I gave them 700ml of water with the growing schedule nutes; yesterday they were quite dry, so I gave them 1L of plain PH'd water. This was for preparation of the pre-flowering schedule feed I will give them tomorrow. Let's see how it goes, so far so good! D32 - 8 Aug - I have taken the advice from all the comments and answers to my question; I have done some LST on all of these ladies. Only the one WW's main stem is pulled to the side, the rest already have too thick stems... For all 6 of these ladies I have pulled open the very first 4 branches from the bottom and one or two of the third set from the bottom just to open them up to more light. This was last night and the pictures are of this morning, they seem to respond very well to it. Can already see a bit more pistils and they are all facing up. Still keeping at the pre-flower nutes until the end of week 5. For now, they have had their last feeding on day 30, late the evening and I want to have them dry up a little more before I water them again - I assume by this afternoon. So far so good!! Current height: WW1 - 35CM WW2 - 35CM WW3 - 55CM PL1 - 50CM PL2 - 55CM PL3 - 58CM D35 - 11 Aug - The stretch is hopefully over soon..... They have gained about 10CM average in the past 3 days. Light is sitting at 45CM+- from tops, I have moved the tallest ones to the sides, with the shortest ones in the middle; it seems to even the distance from the light in a way. I know that I am losing a lot of light at this stage tho. Nevertheless, I have accepted my first-time-growers-fate (lol) and I can just hope for the best at this point. I have learnt a lot from this grow and I am definitely going to improve on the next one. For now, steady as it goes. Feeding approximately every 1.5 days with 1L of bloom-schedule nutes. My one Purple Lemonade has very strange leaves and some of them seem slightly deformed and lime green on the inner part of the leaves. I have flushed, and I have also done a week of just water, I reckon it is just this specific seed that was sort of bad. End of week 5 height: WW1 - 45CM WW2 - 42CM WW3 - 59CM PL1 - 60CM PL2 - 66CM PL3 - 70CM PS: In these past 4 weeks I have learnt so much from other growers here on GD, so a special thank you to each and everyone of you for guiding me thus far. :) Many blessings to everyone, stay safe and good luck with your grows.!
