She's in Coco. Light distance is at max for the lamp (18"). 78F /70% humidity. Her last feed this morning was at 740 EC /5.8 ph. We're going to 1200 EC in few days to start wk2 feed. Leaf color weird. Upward curl too? Something to do here other than be patient? This normal?

Most of that applies to soil which is totally different than coco. My first week feeding is always 1.0 ec and second week is 1.3-1.4 ec,plants are happy about it because they are in coco and looking for feeding to gain energy. autos or photos doesnt matter.Your seedling doesnt have signs of overfeeding,dont judge by ec yet. Ec is not something to follow strictly,ph is much more important. This seedling is looking good for only 4 days,keep doing what you are doing mate.it is still establishing roots,dont expect anuthing magical for first week.week 2 will be where it'll explode. in case of burn,you can safely back off nutes a bit and recovery is within a couple of days at most.coco is faster than soil,no need to be scared.sudden problems,quick recovery.i see you feeding schedule,you cant overfeed with those dosages.just wait for your seedling to settle roots in coco which takes about 10 days.patience

No problem dude. Early grows can always a bit nervous. I hope your name doesn't represent where you grow, I grow in loft and it can be quite hard work getting a good environment.

Ok. Thank you @gmslave @hashy. That website I'm using is obsessed with CalMag def. His week 1 schedule is all about that. Maybe I should just start week 2 which is more N heavy relative to Week 1, but stay at this EC for few days until she improves? ThnkUSoMch!!!!

Unless you have all the bells and whistles that a professional grow up has, meaning one perfect environment with real heavy lighting., do not follow that coco feed chart... That rate is for the utmost perfect conditions. Cheers

That's a little hot mate. I wouldnt go to that. Your better to do it gradually as you wont cause significant damage that way. Let her speak to you. If you over feed it's harder to undo than under feeding.

When the water evaporates it returns to a neutral PH (7) no need to balance bud. It wont be watering them. She will be getting it from the soil. I've checked out VPD ratings and the optimal RH for you would be 65% that covers your temperature fluctuations from 66°f-84°f so you wont have to worry about it again for a while. I think she has taken the feed well. Not showing signs of burn. I just like to keep between the recommend amounts. Green crack is a heavy feeder so that's probably why shes taken it well. I'd keep your feed at the same EC for the next one then the week after increase (just my opinion) she will then tell you a little more in terms of her colour. I dont think shes unhealthy. Just a little lighter than normal.

Is it possible that my humidifier is watering the plant because I had it too close to the plant in a 2x2 tent? So the plant is getting the wrong PH all the time? Do you guys Ph balance the water in your humidifiers?

Your environment isn't that bad, you could do with humidity at around 60%. I would back off your nutes like I said before. You have gone with quite a lot of cal mag compared to grow micro and bloom. Perhaps drop that down to 0.2 to 0.5ml/L while it's so small. Sorry for the 2 reply but I looked more closely at your diary.

400 ppm 0.8 ec for sprouts and every week increase 100 ppm so next week feed would be 500 ppm 1.0 ec next week 600 ppm 1.2 ec next week 700 ppm 1.4 ec next week 800 ppm 1.6 ec and that should be good until your ready to flower. If it is an auto you stop around the 5 to 600 ppm range unless they are showing you they need more food. Never increase more than 100 ppm at a time whenmworking up your feed. Cheers

@hashy Light green leaves? Over fed? She has no signs of burn. Doesn't seem right.

Hi mate, shes looking great! Nothing to worry about at all. Humidity is a little high. 1200 EC feed is seeming a little hot. I'd recommend gradually increasing. That's not far from doubling the previous feed. Back to the humidity, I'd recommend looking into VPD. heres a really useful link that explains it all and gives you the optimal temp/RH ratings. Hope this helps and good luck with the rest of your grow 👍🙂

You have slightly over fed. Week one more like an Ec0.3 to 0.5 week 2 I would aim for 0.5 to 0.7. Week 3 0.7 to 0.9
