Hello to all my autoflower growing friends! I figured we needed a single thread to come and socialize about the wonderful world of autos! Share you knowledge or gain some insight on how to grow these amazing plants.
I’m fairly new to this but I have run Mephisto genetics Walter White and Double grape, and Fastbuds White widow and Lemon cherry cookies autos. I still have a lot to learn but I’ll help where/who I can
Please help. I’m embarrassed to post these I feel like I knew better somehow. I moved these from smaller 1/2 gallon pots to these larger ones a couple days ago. Pre flower snuck up on me an I think I may have nitrogen toxicity. Open to any and all advice! Please and thanks in advance!!!
Based on the color and where it is it looks like nutrient lock out to me. I also see clawing on a few leaves which I had due to pH imbalance. Check your run off or soil pH. Don’t use the cheap soil pH meters that have the 2 metal posts. Get a good pH meter and do a run off test and a soil slurry test from by the root zone. I like to keep mine around 6.5-6.8ph. Too far either way and nutrients don’t get absorbed. Also check your ppm or EC which ever method you choose. Check your run off for how much nutrient you have in your soil, it might be too high instead of not enough. If it’s too high you will need to flush your plants, too little and it’s as simple as adding more.
i doubt nitrogen toxicity, that would make dark green and burnt tips with curl up. whole host of other possibilities. did you use new batch of soil mix? what is ec of the overdrain? even if ec is ok i’d flush with plain water untill clear runoff , mix last flush with grow at ec 2 and pray a little. or repot in fresh soil from new batch. no amendments, can be adding bad stuff that way, even organic stuff can be ‘off’
Sorry, I forgot to say I like my ph to be 6.5-6.8 if I’m growing in soil. If I’m growing soiless it’s got to be lower I believe it is 5.8-6.2 is the sweet spot for that.
hey bigworm, ive been growing a long time love todays autos. way easier than keeping mothers. tried fastbuds strawberry banana[favorite] humboldt seed stuff and seedsman fatso f1 ,northern lights and gorrilla candy. tried others in the past, and probably 100 photoperiod varieties . pic of n.lights at harvest
Looks frosty! I love autos for the simplicity as well as the short turn around. I’ll be doing some Fastbuds blueberry auto and bubblegum auto next time I get in the tent. I can’t run anything in the summer due to electric loads from running AC, so I wait till early fall. This is the hardest time of the year for me, waiting to get another started and seeing everyone else’s grows.
Hey BigWorm thanks for starting this brother! Big fan of Mephisto and growing autos in general. I’d be interested to see what different genetics everyone has in their auto collections. Here is my humble auto seed collection. As you can see, I’ve grown mostly Mephisto for autos, though I’ve recently started expanding my collection outside Meph and and am moving towards old school genetics for a while, starting with my next grow which I will start sharing soon. Bottom right Skunk is Sensi Seeds, Mazar is Dutch Passion, and Northern Lights is Seedsman.
I’m afraid I messed up by moving them to bigger pots when they were just starting to preflower. I used regular MG. for on an pro mix for the other. But that’s when problem started. Thinking got a build up of nitrogen. Should have switched budding nutes a week or so ago. Definitely gonna check my runoff, I do check my ph every water and feed….I’m just so annoyed with these two lol. Thanks for advice so appreciated!
If you stressed them, they should recover in a little. Let’s hope they weren’t so stressed that they herm. That would be the worst, worst case, but I think if anything they will probably just take a little longer to finish and may stay a little smaller. I always start them in their final pot, usually 5-7 gallon. What’s your runoff pH?
He’ll yeah! I’ll have to get my packs out of the storage fridge and get some pics up.
I just got my lemon cherry cookies out of curing today!
It’s a little low. 5.7 5.9. I just flushed em good. Ppm was ridiculous 900 on one and I got some crazy 2500 on the other. It was the dang miracle gro soil pretty sure. But flushed until I got em both acceptable #s so hopefully they’ll pull through. All my others are thriving knock on wood lol sure appreciate ur input brother!
All good! That’s why we are here. You can raise your ph by adding some 7.0 pH water and do it over a few days so you don’t shock the plant. I’ve heard baking soda helps but in my opinion it’s basically pure salts so I’ve never done it. What I do recommend is getting some recharge and Mycorrhizal Fungi to build a microbiome that will regulate your ph on it’s own. What I really recommend is use living soil. I use it most of the time and unless I really mess up, pH usually stays within 6.3-6.8 automatically. I’m cooking some soil up now that’s been going for 5 months. It’s a mix of buffered coco, ocean forest, happy frog, blood meal, bone meal, dolomite lime, gypsum, kelp meal, mycorrhizae, biochar and worm castings. There might be more but I can’t remember off hand. It’s ready now but it’ll be really good by the time I do my next grow in 4 months. The big bonus to it is, you don’t need to add nutrients for the entire grow of an autoflower and you can reuse the soil by adding the ingredients to the used soil again. Up front it’s expensive to start and takes time but once you reuse your soil it pays for itself. If you mix enough initially, you can use half of it and when you swap your plants out you can use the second half while the first half cooks again and recharges.
How do you guys feel about using a “SHPS” thru entire grow or using MH at first then switching? For autos of course.
Hello fellow Auto growers! Definitely going to be tuning into this thread a lot.
I’m currently running Fast Buds Pineapple Express Auto in a 6.6 gallon Autopot with Cronk Nutrients. So far, I’d say it’s going great. I’m currently at the tail end of week 4.
Hey this is my first time growing I went with seedsman Alaskan bannanaberry and wedding cake. Haven’t really did anything haven’t even fed them. Growing in 3.0 living soil
I have no idea about either of them from personal experience, only what I see and read.
What ph is going in? And whats going in….what run off ph? Very important!
