Stealth’s First Grow

What's your air intake like ?? If air flow is good and it's not a heat stress issue id get some Epsom salt mix week mix in spray bottle and spray plants just before lights on then water with a higher nutrient level then your currently using... Epsom salt will open up the pores in your leaves lol that's the way I describe it 😂. And they will uptake light and nutes alot better spray once and wait for a couple of days to see results 😉

The down curving leaves like that are usually a sign of them being kept too wet. Try to lift the pots up to get a feel for how heavy they are before and after watering them. Try to let them dry out a little bit more than usual before watering again but not until the point where they wilt. The leaf blades should start to straighten out as she dries out a bit. You'll get used to waiting to water them when the pots feel lighter in weight. If your having trouble judging try using an electronic digital moisture meter I use one all the time. It is difficult to tell how much moisture is in the middle and lower parts of the pot this tool will help you judge how wet or dry it is. 👍

it can be overwatering, also what medium u using? i have similar issues with coco coir so now i mix it with spagnum mix so it holds water better. its good to have a soil that stays humid for a couple days, coco dries out every day almost

Hope my answer to your grow question helped you out. Feel free to message me anytime. Look forward to following your grow.👍

When the leaf stem is erect and the leaf is flaccid 🤣😂 it means your overwatering if the leaf stem is dropping with the leaf then they need more water. Hope this helps. Just wait an extra day or two before your next watering and the leaves will pick back up p.s if your intake is not sufficient it will make soil stay wet alot longer then you want. I learnt this on my first run and invested in a top line 8 inch exhaust 👌

Good luck 👍🏼

As for watering lift pot everyday after watering to get a feel for weight. When container is light time to water

To your question in the picture description, the advancing of purplish streaking and colour is lack of phosphorous. You can see it in week 9, and now more progressed this week. You either need to give some food with phosphorous, or if you are feeding plant food already you may just have an imbalance or something locking out that nutrient. Some strains use lots of plant food and you’ll see that more easily that others. Once it becomes purple it won’t go back to green, so you may solve the problem but it will still look like that. Check the tops of the branches on the very new growth, and just try to keep that a nice healthy green colour.

They look like their starting to bounce back now. What I use to do when I was outdoors and I mixed a batch of super soil that was to super and was killing or stunting my babies due to too much of or to little of certain trace elements was gently seperate pot from roots,get a hose and a bucket and wash all the soil off of roots ( must use hose to gently wash soil away and dip rootball in and out of bucket). Then transplant into soil that had next to no fertilizer in it, or Coco with no perlite! Then water with seaweed extract for a week then you just go back to normal fert routine. Hope this helps

stop biogrow for sometime and reintroduce at 0.25ml/l, at most 0.5ml/l... its too strong. i always start low and go max 1ml/l... and I think they are not getting enough light.. how high is your light and what light is it? hope I could help. happy growing! =) Tchau, do Brazil.
