Hey guys
Day 26 now and have a problem! Have seen practically no growth in the last few days. They reacted very well to the lst and straight after they grew into it nicely. I continued lst daily and they righted themselves almost immediately, but have not continued to grow.
There’s two things that I can think of that may be the cause...
1. Too much continual lst has shocked them and they’ve slowed down.
2. The light feed I gave them was a mistake. They were showing very light signs of n tox before the feed and still display symptoms now. It had been three weeks since sprouting without any nutes apart from rhizo so felt it was time. This soil seems so damn hot! Wondering whether I should of pre-watered to run off to tame it.

Here’s a chronological timeline of pics from the last few days. Also to note, the first set of leaves after the cotyledons are yellowing.

Pre-lst day 22

day 23

day 24

day 25

day 26

I don’t think this is a ph issue, but I’ve got a soil probe arriving in the next few days just to check. It could be lock out, but damn, the feed I gave them was like 0.2ec and they were growing seemingly fast.
They will be dry in another day, so thinking I give them somewhat of a mini flush. Maybe 2-3 litres each of plain water so at least they get some run off. I will also hold off on any more lst, probably give them a fair few days after they’ve recovered and growth resumes.

All and any thoughts much appreciated!

More food bro. They need more food! .2 EC is low for pre flower. It should be like .8 to 1.0 minimum with that being a .7 scale or at least 650 ppm or so of food at this stage.

At that stage I normally feed around 800ppm or so.

does he have n tox? why the yellowing I have the same issue on one of mine but mine are at day 43 and have had this from around day 30 but bit more severe with clawed down dark green leaves very slim leaf not really growing with a few yellowing tips pot seems cold to touch but probes at 26c has started to flower a week ago I was also tempted to flush but because I'm in coco I was told maybe not a good idea because they would be no food I was thinking of disposing of it to create room for healthier ones it seems even the experienced have issues other than your issue atm wombat they look like they was doing well lst looks a good foundation for when they grow taller, why have they flowered already so early?

No, looks like plant needs P and there is none left in the food. So P def is what he has. Clawing down, turning yellow, looking a little like a Mag def as well. Feed them.

You can see on this chart, his .2 EC means at best he is feeding her like 140 ppm. That is nothing at all. Much more food needed to get proper growth. Other wise they will die completely and eat themselves.

Don't flush with plain water either, that will take all the food out of the medium, and there isn't much in there to start.

Start with around .5 EC first feeding balancing your nutes properly with NPK ratio at 3-1-2. Second feed go to .6 and so on until by day five you would be at 1.0. Just watch plants, if they start to show sign of nute burn, just back it off 10% or so, if not boost it up again like before until you see signs. Sometimes I am able to go to 3.0 EC on some strains if they are strong. Most end up around the 2.3 range, so you .2 is like a drop in the bucket bro. Trust me on this. They will be fine.

There can't be any toxification of the medium if there isn't any nutes in it man.

Hey guys,
Thanks for the look in.
I was convinced the soil was too hot and was giving them n tox which is why I was so hesitant. They’re not looking that bad, just not growing so much, so will give them another feed tomorrow with higher rates and see how they go. Working with the biocanna range, Vega 3-1-5 and Flores 3-1-6, with bio boost and rhizo additives. Not nearly the range you recommended, hopefully they’ll do.
I’d drawn out a chart before starting and had planned to be feeding around 0.8 about now, but have just been so cautious having seen signs of what I thought was n tox. I’m sure they’ll bounce back, been great growth up until recently.
I do feel like they’ve seemingly jumped into flowering real early, barely anytime just vegging, not making it any easier to keep with my schedule! All learning as I go and happy to see them where they are.
Thanks again!

If you don't feed them, the problem will only get worse. If you really think medium is hot, just run water only through and check run off. If it is higher than say .8, then you may have to flush, but I would bet it is not.

I would feed them and then wait to see. They should be growing fast. The fact they are not is proof they don't have the nutes they need. I feel like you don't want more advice though on the subject, so I will leave you with that.

Good luck!

The training looks really good. I did the same thing with my juveniles and have ended up with a canopy of 48 almost even tops on 4 plants. They look pretty good overall but I agree the look like they need some more P.

Hey bro,
All the help is hugely appreciated mate! I’ll be feeding them today at 0.4ec as you’ve suggested and will work my way up to match my schedule. I’ll see how they take to this next feed and probably feed again next time around. I’ll water to run off today and take some readings.
Thanks man!
