I am at a loss for what is going on. I really need help as you can see by the pictures website but being my first grow I really am still dumbfounded. Growing Ak-48 autoflower from nirvana The setup: 630watt cmh light/only using one bulb at about 4.5 feet off the plant tops/on continuously 4.5'x4.5'x7' tent 6inch exhaust fan w/ carbon filter running on low constantly ultrasonic humidifier/average humidity is around 50-55 Temp in tent is at 75-77 degrees on average Using 5 gallon grow pots with promix hp soil which is non-nutrient based perilite mix Nutrients are Biobizz lineup and photosynthesis plus I had been feeding .25 gallons of ph 6.8 filtered water every third day but this week I felt I had been overwatering and have switch to .1 gallon every other day. I have only fed them once with my nutrient line at 1/4 strength. The lower yellowing had been present before the nutrient feeding.

Hi @Dimebagkilla! pH is almost neutral whereas you need it a bit acidic (~6.2), nutrients were given way too early, soil must have developed some salt buildup and/or nutrients-lockout. I also guess the watering routine was bad and did not follow a wet/dry cycle. Honestly at this point I would throw them away and start over from fresh seeds, but if you really want to save those babies, you will need to change your soil. Your medium have been flooded with nutrients and an inappropriate pH, plants are too small to survive to a flush, so just try to transplant them. Find some fresh and light medium (I like BioBizz LightMix) and don't add anything in it but rootjuice for the first ~2 weeks. If plants are healthy at day 15, start by giving some nutrients but avoid 'PhotosynthesisPlus' and stick to the BioBizz feeding schedule. Start with half of the recommended doses and slowly increase nutrients up to the official BioBizz schedule if everything looks good. Now be warned that transplanting unhealthy seedlings is a risky operation, this is why I would start over from fresh seeds. Hope this will help, keep us up-to-date and happy growing 👊

Hello, my advise will be a little different. I would change the growmedium. If its your first grow i would start with soil. In soil you only have to take care for not to overwater. If you are using prefertilised soil like Biobizz/ plagron) you dont have to care for weeks about PH / feeding etc. You can concentrate on the right light and you watering and after 4-6 weeks take care for the feeding. It needs time to learn about your microcosmos growtent. The right Light, the right distance, the humidity the airflow the temperature. And if you grow in coco the feeding/ the right ec the right nutrients at the right time. Its a lot more to do/ think. Think about buying some prefertilised soil and transplant the Girls it alot more relaxing than now. You can keep our cococoir until you are more used to grow ( Dot have to throw away, you can use it more times) happy growing

hey man photosynthesis plus is a chelation agent which helps break down nutrients in the soil and makes them more available to the plant. That's why you're showing signs of nute burn even though you're not over nuting. Cut out that Photosynthesis plus until minimum week 3 (or in your case week 4/5) , and the plant will recover. or just start again if you dont want a stunted plant. It's that simple. Hope this helps ! 🚀

try flushing with water adjusted to the low end of the appropriate ph 6.2 ish .. flush em good , do it once and leave em be . look for new growth that is good .. old doesn't make a comeback usually.

If you want to learn on this plant. I'd chop the bottom leaves so it stops wasting energy on them and flush out slowly with plain water the area where you have been watering to flush out nutes..collect water from the runoff and test the pH so you can say for sure if your pH is wrong..It looks like you are using an air pot so run a fan on the pot after you flush to dry it out quickly so it doesn't rot. Cut out the nutrients until you get your issue figured out.

What should my target watering amount be? I really don’t want to restart as I already have the time invested and I am using a soil based mix (promix hp)

@Stick I’m afraid to restart because I really don’t know what my watering amount should be when I restart. I feel I am liable to make the same mistakes other than adding nutrients to soon. What is the recommend volume of water for a seedling? What schedule and amount should I follow
