@tschw1, leider weiss ich nicht Foto senden, wie soll es aussehen. Hab schon im alten Handi etwas gefunden. Ich glaube, dass du nachstes mal besser/zusatzlich Licht probierst. V.G.

Hi. Hard to say, where is problem exactly, with unknown pH, EC, soil composition etc... But I would bet on nutrients/pH imbalance. Excess of any nutrient can block some others. You fertilized it with P+K only once but still, this amount without enough light and temp. can cause anything, especially with this unstable conditions. Healty plant in week 5 looks 4x bigger than yours (10+ internodes). I have tried indoor jack auto (some others too) for first time in 15L fabric pot under 19watt bulb (from week 3 under 4x19w bulbs), and its really not comparable. From week 3 it was really crazy (started LST after week 2, because plant already had 6 pairs of leaves and was 15cm high) and each week it grows exponentially faster and faster. Every week defoliated 2-4 fan leaves big as hand. What I want say... Fast growing healty plant is not so vulnerable towards any small mistake or small amount of pests. And about nutrients feeding: "less can be more" Good luck, I am looking forward to this/next week ;)

@tschw1, hi, uffff.... This is overfeeding ! Which scheme do you have ? You are still in veg... https://www.biobizz.com/wp-content/uploads/2023/10/EN-Nutrient-Schedule-EN-2023.pdf You are not in in preflower not yet in blooming phase. In veg, supply only with fishmix 2ml/l + root juice 4ml/l (not so important after 4 weeks, if so, you can decrease to 2ml/l). Good luck in this cold nights

Hi. Now with more sun, are tops of plants looking much better :) Now you can gently fertilize with some grow nutrients. Start with 1/4 of dosage your bootled food (fishmix, rootjuice, bioheaven). Next week 1/2 dosage, 3rd week full) I am using biobizz too... The smallest plant with thin stem can you still supoort with additional soil. I see you still have 2 inches place for soil :P You can add soil into all pots. Cotyledons are now useless so u can cut them carefully or if you want add soil upto them. If so, mix some (10-15%) perlite in new soil layer. I see that crack in soil, it does mean that you have too heavy soil. Perlite can help... What soil do you have in pots now ? As top layer, you can use now fertilised soil mix (all mix if you like biobizz, or equivalent) Every watering lower layer receives nutrients from top layer... Main stem will grow some new roots in this layer in 2-3 weeks. p.s.: sticking wooden supports are dangerous because you can hurt tiny micro roots. So next time you can try wire with eye inserted 10cm away from roots, same which you made for LST, but only for supporting, not for bending.

@Njustice4all87, Oh, sure, in windy and dry weather it can evaporate this amount of water. So the problem could be in VPD. I have this pots too, but inside tent with regulated humidity. Usually so small plant need max 0,5 litre of water 2-3times weekly... Try photone, and look at VPD chart too. ;)

@tschw1, yes, LST for autos... You have 2 months to harvest. So, i think, bring more light to all branches can help. And light... you can use lamp for e27 bulbs which you wish, must not drilling or hanging it... Outdoor photoperiodic you have enough time to grow, no worries if they receive at least 14 hours of light...

Hi. Nice plants. Be carefull with nutrients, you have minimum light, so you need minimum nutrients. Biobizz are very strong fertilizers, start with 1/4 of recommended dosage every second watering, never use more than 1/2 if you have not at least 12 hours of strong-enough light. If so, add some light. In gemrany you can buy in OBI some E27 bulbs, I can recommend osram 19watt 2452lm. Cheapest solution for 15€ and it really works up to 4-6 week before plant leaf are grow to size of pot. Then light angle is too small and you need more power. Just shine 30cm above canopy for 18 hours. But avoid light stress or light burn, so start with few hours, then slowly increase, add 1 hour daily. Then you can decrease distance between canopy and light 1cm daily, up to 15cm. Less is useless because light angle and possibility of light burn. Yes, minus daylight hours if you want let plants on window, but its not recommended in summer months, because sunlight through glass, in isolated room without air circulation can extremely stress plant when leaf temperature raises on 35°C ! So what you need next, is small fan. Wind increases stem thickness. Dont forget LST. With NOT enough light your plant can grow high really fast, and stretch 3x taller in flowering with weak site buds. If wish you perfect weather as soon as possible that you can move them out permanently without fear ;) Viel Spass.

Hi. Let me say, what I see: 1. too much water - for so small plant is 0,2gal/24h too much. Your temp and humidity ? Maybe 0,2gal every second or third day would be better. 2. that wooden support ... let plant to build stronger stem, usually it grow thick in wind, if stem is permanently bending. Better slution would be add some soil. You still have 1-2 inches in pot. 3. now i see other beginning problems: extrmely unstable conditions. Use "photone" app for measure light. Light through window (even though on south side) is sufficient only for germinating in 1st week after planting seed. Next step is slowly increasing light. You need to start with at least 150 micromoles in 1st week in seedling state and slowly increasing light power up to 300micromoles in 1 week, then up to 600micromoles in second-third week. What type of light source are you using ? Light shedule is important too. All extrme changes are stressfull for plant. Good luck :)

Hi, looks like overwatered in weeks 1 to 5. Wish you a happy harvest 😍

@jakethedog, you can still increase light period, but in flowering do it in low steps. I believe 20-30 minutes daily will be ok. It can do some stress, so be carefull. This distance and 20hours of light can cause light burn on top leaves, so watch your lady daily, and do not more "upgrades" together (adding much more water or much more nutrients, temperature a humidity are very important too. Look at VPD chart for autoflowers) You can try add distance and light period too, what causes more angle - more light exposed surface on top of plant. Another idea, but dont know if it works with 60° bulb, is add some reflective walls around for transport light beam to lower leaves. With this upgrade dont forget add small fan, for circulating air and prevent molds. I think your plant grow is slowed down too, because of low temp. But let it so now. More light in future=more heat. Dont know where are you growing, but usually strong lights can increase room temp... p.s.: with this plant height and low light distance from top can cause maturing delay of buds. So maybe the top will show all milky trichomer earlier than lower floors. In last stage of flowering you can then harvest upper quarter and another days/week later you will see how looks rest of plant. Somewhere i saw harvesting 3 or 4 times in 2 weeks after cutting top of plant

@jakethedog, this year im trying cheap emos 19w bulbs, with removed plastic difusor. It really works, but high voltage without covering is little bit dangerous. Already hitted me 2 times :D I cant see difference on plants between sansi and this bulbs for less than quarter price. Only lifetime can be lower, they are shining 3 months without problem, 4 bulbs in distance 20cm for 60cm tall plant... Much safer what i can recommend will be ready products with promo from marshydro, spiderfarmer... etc, with dimmer. Its not cheapest, but it have much more power, dimming, hundreeds od leds, deatachable led driver (heat source).... Or you can buy 2-3 more sansi leds :) p.s.: look at spring discounts, sansi have promo too. I am using same bulbs for vegging vegetables in grow tent, all plants looks happy. What you need is adjust ppfd/DLI, try app for mobilephone "photone" ;) And yes, LST is way. But now too late for you. Now you need more light power. Next time: 1 bulb start with 1ft distance from germinating to 1st week veg, then each week 1" lower. After 2nd veg week apply LST. 4th week after plant stretch increase light distance with more light power (at least 60w). Now you have maybe 600umol at top of plant, but lower leaves (at 0-60cm) do not receive enough light (less than 150micromoles is useless). This is reason, why is better use strong lamps (150w or more) with higher position... If you have at 2feet distance 600micromoles, 1 feet lower your plant receive still enought (+-300umoles) With this one 24w sansi you have 600umoles at 0,5ft, but 1 feet lower you have 1/4 of light. And this is not good.

Hi. You have SF1000D with dimmer ? Didnt know that "D" have dimmer. If it is new SF1000 with concentrated leds in corners, you can save electricity costs with much lower distances and less power adjustment. Ideal for 2 plants in pots up to 3gal, or 4 pots up to 2gal. Simply glow directly above plants with leds concentrated in corners, with half distance and half-quarter power ;) Less power means less heat... It works upto 3.-4. week, then plants canopy is bigger than light angle (and pot area too :D )

Nice noodle :) This bulb is good only up to 3rd week with distance from 30cm (after germinating) to 15cm(3rd week), with plant height 15cm too. Then canopy area, light angle and intensity goes not together... Need add 2-3 bulbs after week 4 and start again at distance 40-60cm. This one will produce minimum yelds.
