26.1.25: I have had a mistake 😕 i spilt some Fish Mix as I was experimenting with a syphon from some aquarium tubing I have. Unfortunately, I forgot to take the syphon out! Ugh 😣 However, it is fish emulsion and very thick consistency. Therefore, I was able to scrape it up with 2 of my business cards up off the counter. So added this extra into the next 2 ltr solution I mixed. All plants were watered with at least 1ltr of dechlorinated water PH'd to 6.3. Containing the following nutrients;- ♡ 3ml Seachem Seaweed ♡ 4ml Biobizz Fish Mix ♡ 4ml Biobizz Bio-Grow ♡ 3ml Biobizz Bloom ♡ 2ml Xpert Nutrients Bloom Booster ♡ 2ml Xpert Nutrients Cal-Mag ♡ .25g Ecothrive Biosys. ♡ 2.5g of Bicarbonate of Soda as PH UP. Unfortunately I have broken my PH pen too. Accidentally submerged it under water, then the readings went crazy. I'm leaving it to dry by standing it up but I'm most likely going to need a new one, which is extremely annoying 😑 I'm going start implementing the Scrog net probably some point next week if I let the plants that are in flower to just grow up now, as I do believe that I stunted Watermelon 🍉 by using too strenuous LST. Hopefully the plants still are able to grow upwards at this stage during flower for all the Purple Punch P1, P2 and P3. We will soon see! 28.1.25: My PH pen has packed up 😣 I've got to wait to get another. It's super annoying 😑 so I'm just judging by memory how to regulate it. Unfortunately, that's my only choice! I'm also out of the dechlorinator 😕 things are not going very well this week so far 😅 I guess we will have to make do, until I can get replenished. 29.1.25: I removed all the plants, hoovered, and disinfected the tent. There were several accidents when watering, causing some debris and splashes. I decided to just go ahead and get a few other things done. It's crazy how quickly things can become neglected! 😣 So I defoliated moderately on all plants except Gorilla Cookies seedling. I have absolutely dropped the ball on my lighting situation! My light was much further away than I thought! I turned it up to 100% and dropped it down to just under 2 feet away. After I reset the tent, I set up my scrog net. I removed 80% of all LST pegs. I am planning on letting the scrog net take over the training from here. I really want to minimise the risk of mould, so I decided to start using my dehumidifier. It has raised up to 73% RH this week, so it's necessary. Hopefully, I will be able to get my dechlorinator and PH pen soon! That's kind of essential to me. It's been a little bit of a stressful day in the garden, to be honest 😅 30.1.25: So I am expecting the arrival of my new PH pen today, as well as my new bottle of Ecothrive neutralise. It is supposed to measure the TDS and EC in addition to the standard TEMP and PH, which I had previously. Obviously, time will tell if it's any good or not. I realise, much too late now, that my lighting is very insufficient for this many plants. I need double the watts at least, and coverage is very poor. I remembered I had an old LED floor lamp, which was in a corner being unused. I decided to take the stand off, and Zip tied the pole onto the tent pole at the back left corner. I have no idea what the wattage is, and it's quite pathetic 😅 but I mean, I might as well use it, being as I definitely cannot afford more lights! 😣 Next grow, I will probably only grow 2 plants, max 4, and just use larger 7-10 Gallon pots. Being as I ran out of dechlorinator, I only watered some plants properly because I only had enough to make 6 litres. When my pen arrives, I will get everything properly watered. 31.1.25: The leaves of several plants are showing signs of iron deficiency. This is likely due to my PH pen packing up earlier. I now have a new pen. Due to this, I decided to use my Seachem Prime, which I use for my aquariums. As I wanted to get them watered properly, and my Ecothrive Neutralise hasn't arrived yet. I watered each plant with 1ltr of dechlorinated water PH'd to 6.0. I added .25g Ecothrive Biosys to the water. May give them a breather on the nutes and just use the Cal-Mag and Biosys. Being as I've just topped dressed with rich fertilisers, I'm sure that will be OK for the next several waterings. 1.2.25: Watermelon 🍉 has started flowering. The size and shape of her is quite laughable 😅 Retrospectively I started the LST too early and went in too heavy with it too. That obviously wasn't a great idea. Still, this is my first run attempting to do LST, and I have a whole bunch to experience and learn from here! 😅 We may get lucky with a stretch. Who knows right. I remember this one was supposed to finish really early, like 10 weeks or something so hopefully will get at least a bit bigger 🤞 Also the new growth is still a little bleached out. Hopefully the switch to a functional PH meter will correct the imbalance which may have occurred due to my previous one packing up. Snipped another couple leaves which were annoying me 😅 I realised this is one of the pots I put my clay pebbles the bottom of. So I've probably not been watering enough, as she's right at the back, and assuming all was good because the pot was heavier. Removed a couple of leaves from Bubble Kush

Some strains aren't good for training especially heavy training like that, and autos even more so with the 5wk veg.I top and train mine but nothing as heavy as yours.I finished my 2yr affair with autos last year and Im back to photo then its up to me how much veg they get as I like to grow big plants.

@oldskoolkool, I can definitely see how the control over the photoperiods would be beneficial. This is only my second run, and am ready to mess it all up royally! 😅

Try not load up soil with too much sugars prior to flower as it changes the metabolic pathways leading to a delay in the development of floral clusters. Also keep a close eye on the humidity over night, running a high 70%+rh daytime will shoot up at nights when temps drop, especially as plant gets bigger. This is not a criticism so please don't take it as such, your plants is small for 7 weeks, not a problem at all for photo periods but it's a indication not much is getting done each cycle, once you switch to flower if not much is being done then buds will not get much done. Raise ambient temps at canopy to 79-80f, leaf surface temps always run a couple degree f lower than ambient, do thay and hold rh to 50-55%, small tweaks will really help with getting more done. Best of luck , look forward to seeing flower time. 🌼

@Ultraviolet, Hey, thank you for taking the time to give me your input! I really appreciate that! You are quite correct, I have just started up my big dehumidifier. The temperature is between 40-50% RH now. This plant I absolutely stunted due to extreme training. Which is a real shame because she started out so strong. 😕 still I have learnt a valuable lesson with her, and moreover the Purple Punch autos I have in this run. Waaaay too much training and I've sadly ruined those two plants, they could have been phenomenal. 😅 I'm here to absorb all the knowledge I can, so thanks again for the solid advice 👌 🍃✌️

There's and old saying KISS.Keep it Simple Stupid.They do really well on next to nothing and respond well to stress.They call it possitive stress.Iv just chopped 30% off the top of mine,over 1foot and they'll come back better for it.

@Kirsten, A lot of us get into going overboard, I certainly have and still do to a degree. I know some of the things I use wont make a difference to the outcome but I know my plants are really healthy and the soil microbes are fed.Thats a whole different world to learn about.The soil food web which is most important when using organics. They're on a better diet than I am,ha.and I eat organic whole food for the most part.

@oldskoolkool, 😅 yes, I'm sure you're right bro! I'm stupid and I love to make things complicated 💯💚✌️

I know how you feel.I think 1 of the best things aboiut photoperiod is cloning.I'd do nothing but clones but its still illegal here and having 10 more plants could see me getting locked up and I'm getting too old for all that nowadays.I have done some big grows which would of seen me go away for a couple of yrs.

@oldskoolkool, Ah yeah, that sucks. Better to be safe than sorry eh?! That's a smart way to go though, cheap and also you can preserve the best phenotypes! 😉🍃👍✌️

All my autos were fast buds, I still have around 50 beans in the fridge as I went mad when they had a buy 1 get 1 free offer. He certainly produces some top strains but everyone does nowadays. I didn't train my autos at all,from what I could see it made little or no difference to yield but I do understand the interest.They produced between 3-5 oz each Light leaks are always an issue. I guess its the zips of your tent. You could always throw a blanket or tarp over it.If you're determined to stick with autos check out ones that other people have had good results with.Fast buds have great site and info about their strains and say how vigarous they are.The wedding cheesecake was my fav for growth and strawberry pie for effect.

@oldskoolkool, yeah I've just started the Gorilla Cookies Autoflower by FastBuds and topped it about 14 days old. It's a very strong and healthy looking plant, so I'm very excited to see this experiment 😄

I can't recommend seaweed/kelp enough.Iv never grown without root boosters and kelp is in all roots boosters all veg boosters and a lot of flower boosters like big bud and cannas boost.You can see your plants pick up.You've alreadu got your humic acid in your top max and they go great together.Biosys has seaweed in it but your plant will wantr more.Don't forget to stand your water for 24hrs as the cholrine kills the microbes in the biosys.

@oldskoolkool, Yes I have liquid seaweed extract, and also use Ecothrive Flourish. I'm right at the end of my Flourish. So this week I'm using the seaweed. Can't deny it's good stuff! I also want to try out some dried kelp that I've found, but this is getting rather expensive 😅

No need to worry about sallt build up with organics.You could probably do with less coco next time 12ltrs is more than enough with 5wks veg.I mix my feed in a big bucket.I'd be soaking the whole pot now with 2ltrs.Big roots=big fruits small roots=small fruits.Roots are often over looked but theyre just as important as the top half of the plant.Look at the size of my plants and they've got around 15ltrs in and I feed every other day for the most part.

@oldskoolkool, I've got 5 gallon pots. I have started to really ramp up the feeding volume, they're indeed very thirsty, and hungry too! They're really getting going on building those fat buds! 😍😋🤤😅
