Good evening all. First time grower here. I have two plants one is doing great as far as I know, the other is growing very stubby, almost looks like a pancake. I'm just wondering if maybe someone could tell me why? Or if it's normal? My apologies I'm a true rookie at this and just trying to do what I can. Here are my conditions. The plant in question is named Peppa. The other plant is named Winnie and i just tied her down. What type of medium; soil or hydro? Soil What brand and type of soil? Roots organic lush Indoors or outdoors? Indoors What strain? Grape rock candy x banana butter cups How old are the plants? 38 days What type of lights and how many watts? Spiderfarmer 4000 How far from the lights? 24 inches or so What is your watering frequency and source of water? When dry, so usually about every other day or so. Water is dechlorinated water with a ph of 6.1 What, how much and when was it fed? NPK? They were both transplanted into 2 gallon pots about a week ago with a 4-4-4 dry amendment What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? Average about 74degrees and around 45-50rh usually around a 1.2 -1.3 vpd What size pots? 2 gallon right now Any bugs? Look real close. A few gnats, nothing major Any other pertinent info? None that I can think of. Here are pics of both plants. Both were planted at the same time and getting the exact same treatment. Light cycle is 18/6.
Nice job on providing details explaining your set up. I would say she's stunted due to overwatering and overfeeding....which manifested into gnats and dark green & twisted leaves.... very strange to hear a newbie talking about VPD though....
i do ALOT of research before i get into things lol. As for the twisting and stunted growth, is there anything i can do to help her get going? and when i say theres gnats, there were like 4 on her yellow sticky card.
I'd suggest moving your light up so your plants stretch a bit. 28"-30" from the plant top. And dim it to 50-60%. Mist foliage with water daily and or bring your relative humidity up to around 60%.
Could be nothing or normal. These are all the same strain all sativa dominate hybrids that one grew indica dominate. Its half the size of the other 4. Looks like you may be beating them to death with the fan tho generally thatll cause the wavy looking leaves. It's the lower left in the final pic. Has 20 mains without topping. Just grew short and bushy. Those others have 8 to like 12 or 14 topped not natural like the short bushy one with 20.
So from what I am gathering, I should turn off a fan or two, up my humidity, and lowering my watering? Also, the leaves aren't supposed to be that color???
No I guess there's too much varying information. Disregard mine and continue, never did I mean cut fans off I run 5 in my flowering tent.
Your VPD is in the range of late flower. 74 degrees and 45-50% rh=1.4-1.5 (kPa). A VPD range of 0.8–1.1 (kPa) is commonly known as ideal in the vegetative stage, while a VPD range of 1.0–1.5 (kPa) is commonly known as ideal in the flowering stage.

They are too dark in my opinion, typically due to overfert. Regalia, which is a powdery mildew fighter can cause leaves to darken as well but different mechanics.
If yall you've fed is 444 it takes a week to start breaking down.... guess the leaf change happened over night or over the last few days. Imo 6.1 ph in a organic neutral to slightly acidic soil would be more damaging
Would this cause one plant to be growing fine and make one looking like it's a pancake? I just can figure out why one is all stunted and the other is fine doing the exact same things to both plants?
Yes. All I have done was use the soil with worm castings and a 4-4-4 at time of planting, then on day..... 28 I replanted from a cell pot to a 2 gallon pot and used the same mixture. For both plants. Peppa started out fine from seed and then her next node was just really close and have been that way ever sense. There's growth underneath but she just looks squished. Anything I should try? Change? I'm gonna try moving the light up a little more maybe?
Imo nope everything is fine. You're wasting amendments using them so early tho. Unless medium has none. Nutrients aren't needed until plants fade, or in final pot for a month. I'd raise ph to slightly acidic and just give distilled or ro water since you've used amendments so early using tap with ppms can cause issues. Once plant is large enough to withstand the extra nutrients you could go back to tap. Rn youd have the medium nutrients, nutrients you added plus tap ppms. I dont ph organic soil mine either get 9.2 tap or 9.5-10.0 ph ro if you stopped phing now tho after applying 6.1 the ph swing would probably effect them negatively. I'm not at home or I'd get pics of some of my lower leaves. My floor oscillating fan is messing up so it doesn't sway as much beating some of my lowers constantly they look like your leaves. Why I suggested that. I slightly over feed my plants every grow and haven't had leaves go crazy like that, generally with a tea not by slow release ferts. I'm also growing sq1 Side note I've started using down to earth vegan mix. I'm liking it better than 444 all purpose. worm castings wont burn plants I do add that to starter pots and transplants, since castings add micro biology and many nutrients at low levels. I'll add once those seedlings were removed and I raised my light that didn't effect that ones growth at all stayed short and bushy. I always start low with low wattage and raise light with wattage as plants grow. Imo 180 to 200 watts far away wont do anything but make them stretch. Only reason in those pics the middle and lower right plant are smaller are because one I had to restart so it was over a week behind the other lost its cotyledon and first true leaf upon sprouting stunting its growth. They both caught up fine
No, it can cause your leaves to deform and can contribute to stunted growth. Your plant structure is likely from its genetics. Your leaf color is from excess nitrogen. By moving your light up, it will cause your plants to stretch to the light. By lowering your light's intensity it will process less nutrients by lowering the rate of photosynthesis. Your plants will return to a healthy medium green color. Water wisely, over watering is the biggest mistake newer growers make.
genetic differences, plant health differences, environmental differences....all things can play a factor. You could have two plants, and one is weaker or not as fast growing then the other, but you're watering and feeding the same...what would happen? This is why it could be argued to grow from clone only...
I have Peppa on a small stand, I will take her off that so she is farther away from the light to see if she starts to stretch out a little bit. The light is a 450watt max light, I currently have it set to 200 watts, I had it set to about 110-115 during their time in the cell pots. I just turned it up when putting in the 2 gallon pots. So I should turn it back down? Just a little or back to the 110-115 wattage? Sorry for all the questions. I enjoy growing these plants and this is all some great info! I appreciate all of the input!
Think of growing cannabis as if you're the conductor of an orchestra. Charts like DLI and VPD are the music notes. In order to make sweet sweet music, everyone needs to be tuned accordingly and in sync. You can crank the lights all the way up, but if the humidity is 'out of tune' - don't expect too much... or if you're blasting CO2 at 1500ppm but your light doesn't have the umol intensity capabilities....the CO2 won't be utilized... Or everything else is in tune but your feeding or watering process is broken...which can be plant specific in the case for home growers due to wide genetic differences...
When I transplant, I don't find increasing light intensity helpful when we are trying to focus our growth in the root zone first. We use this same low light technique when starting clones. All our focus then is on making roots.
