Englisch: We have now reached week 2 and the ladies have tolerated the early repotting a little worse than expected. But they recovered from the shock. All 3 biscotti plants are now growing wonderfully and look great so far. With the Gelatos, 1-3 are very uniform and growing well, but 4 and 5 are lagging behind. Time will tell if all 5 will make it to flowering. The two Cookies x Key Lime Pie are unfortunately also a little slower growing than the Biscotti and Gelato 1-3, but I'm so interested in the strain that I'm keeping both plants. Now we come to Herz OG, the strain I was most looking forward to. Heart OG 1 is growing relatively OK, but is clearly lagging behind the Bisottis and Gelatos. Heart OG 2 is growing quite slowly so far. Even slower than number 1. It also shows a mutation on the first pair of leaves. Let's see how it develops... The fertilizer has also been added since the beginning of week 2. Here I use the Athena Blended Line and stick to their feed schedules and the hand watering strategy. Deutsch: Nun sind wir in Woche 2 angekommen und die Ladies haben das frühe Umtopfen doch etwas schlechter vertragen, als gedacht. Aber so langsam erholen sie sich von dem Schock. Alle 3 Biscotti Pflanzen wachsen wunderbar und sehen bisher toll aus. Bei den Gelatos sind 1-3 sehr einheitlich und wachsen gut, jedoch hängen 4 und 5 hinterher. Es wird sich zeigen, ob alle 5 es bis in die Blüte bringen werden. Die beiden Cookies x Key Lime Pie sind leider auch etwas langsamer im Wachstum, als die Biscotti und Gelato 1-3. Der Strain interessiert mich jedoch so sehr, dass ich beide Pflanzen behalte. Nun kommen wir zum Herz OG, die Sorte auf die ich mich am meisten gefreut habe. Herz OG 1 wächst relativ OK, hängt jedoch klar hinter den Bisottis und Gelatos hinterher. Herz OG 2 wächst bisher recht langsam. Noch langsamer als Nummer 1. Sie zeigt außerdem eine Mutation am ersten Blattpaar. Mal schauen wie sie sich entwickelt... Außerdem wurde seit Beginn der Woche 2 der Dünger mit eingebracht. Hier verwende ich die Athena Blended Line und halte mich dabei an deren Feed Schedules sowie die hand watering strategy.

Weekly update. Sorry it was a late update this week I was out of town (Bizcon2024). Wow have they grown, I'd say doubling in size. I've upped the watering to 1000ml daily, this week I'll do a major defoliation and lollipoping. All in all Happy Growing

31/03 😐 encore une qui me fait un coup tordu. en fait, elle est Loing d'être raté. mais elle a pris du retard.. Pour une auto.. c'est bizarre.

11/3 Week 6 Watered roughly one gal each @6.5PH, Fish Sh!t 5ml - Karo 1 tps /gal Flower Girl still in the pot, no deficiencies I can see, well new ones :) Mag-Sulfur Foliar spray (Epsom Salt 1tbs/gal) on all as leaving cal-mag out this time Moved the two healthy plants to the center of the light, they can use it, the others might respond well to lower levels. 11/4 Better pics uploaded Placed Brandy on a block of coco coir to bring her canopy up to Layla's level. Moved Maggie to the corner she has a stretch going that I HOPE is ending and I dont want to set the lights to her. Watching that plant carefully Considering a PK boost watching only Layla for that as the other two ... well hell what can they tell me? 11/5 Working to getting the canopy under control with one stunted plant and another stretching like crazy. Put a block under Brandy to move her up level with Layla. Trained down Maggie this growth needs to end, it was already stressed. Still giving light pref to healthy plants. 11/6 Raised lights three clicks, increased extraction, showing some heat stress in those edges. 11/7 Good results on the heat stress curling has ended. Noticed some improvement also in the tops of Brandy and Maggie, so raised lights another couple of clicks. See if it continues, coming up on a make or break feeding in couple of days. update Foliar Feed All - Epsom Salt 1tbs/gal Well Maggie's came today - To runoff- 1% peroxide - 5ml CalMag - PH 6.8 Hitting Sulfur as hard as I can. Before pics posted Brandy not dry enough waiting Layla just got fed but she got pics too as there are signs of Mag deficiency 1 gal 6.5 PH - CalMag 5ml - Fish Sh!t 5ml - Bio_Bloom 5ml as a PK booster JIC 11/8 Video of plants 24hrs after giving Maggie the h2o2 1% , think she looks better lets see how it goes 11/9 48 hrs after treatment and Maggie is showing great improvement, serious improvement in leaf structure and coloring. Pics at lights out tomorrow new week anyway. Brandy showing some improvement but its early. Canopy is level now so lights set to Maggie being slightly taller ***Last update before the new week.*** May have found ONE of my problems,certainly not THE problem, but one. I have been using lemon juice as a PH UP since we went organic late last spring. Because of all the problems I have been looking into a lot of things further and found that lemon juice begins to degrade as a PH up after as little as an hour. A 6.0 PH water gallon can go to 6.5ish in 24 hours simply sitting in a dark corner in a jug. One can imagine the variances in soil. Why I dont know but I am going back to chemical PH additives post haste in fact its already done.

This is a must grow strain for anyone that likes a good balanced strong sativa , it grew well despite dripper and timer issues and had a really good medicinal side for crohns disease whilst leaving me energised and uplifted . This plant continues to stretch right until harvest even with heavy defoliating it ended up 150cm tall. The smell is really strong and differs between pheno types. One grew with almost no pistils/stigmas and was very frosty, this one could have continued Even after 9 weeks flowering . Overall this has taken over as my favourite sativa ! I WILL grow this again for sure and would recommend it to anyone who likes sativa or citrus smelling/tasting flower 💚 NB: I didn't weigh the bud wet so ignore the guess in the grow report.

Settimana dal 23-29/08/2021: Innaffiatura/Nebulizzato. Eliminazione di foglie in esubero. Aggiunta di 1 lombrico per mantenere un terreno adeguato, da ora in poi le dosi di fertilizzazione sarà minore. Tecniche LS/HST/Topping.

It’s day 33’from seed. All of the plants are really healthy. The plants have a really great root system at this point… I am currently slowly moving the light intensity up to the veg area. Now that are in a groove they are about to explode… I’m hoping I can flip the plants to flower in 1 weeks but I’m thinking I will wait to weeks and let them get a little larger. The plants are just now starting to look visually different next weeks update I will be ababoe to go into the visual differences, they are just not that extreme yet to really talk to much about.

Sorry about not putting information about the grow I hate it. I wish I could just put up videos and pictures but I do try to provide a little information and it's really not much because I'm not doing much I'm amending the soil I'm adding micro nutrients and worm castings and sugars I stopped the Cal Mag pina colada stray is set to go for 9 to 10 weeks gummy bears are set to go for 8 to 9 weeks so we'll look at that three more weeks

Just Started. Waiting for spread

Second grow after mangling the first lol

420 Fastbuds Week 4 Gorilla Punch Auto Hello Hello grow family. This week has been good for the girls. They transitioned into flower showing flower sites all over. Still no big signs of deficiencies so will keep up the same routine besides adding a little GH CaliMagic. Starting to stretch more so can't wait to see just how tall they'll get. All in all Happy Growing

Updating this 2 days late today is day 23 but the pics were taken on day 21/22. The leaf strip was a bitch, took me a day and a half to do the 5x9 and I'm still workin on the 4x8. I would have paid someone atleast $400 to do this for me it was brutal my back is toast. Hopefully it will pay off in the end 🤦‍♂️ everything looks promising tho.
