Nutrients First try at Biotabs, not looking good, where did I messed up?

[Fizzback]

Hi,



I had to left my 3 seedlings (Auto Colorado Cookies, Green Crack and Think Different) just after putting them in soil, 2 weeks ago. Neighbor was in charge of the watering, and they were like this when I came back.

First try at Biotabs starter kit, in biobizz lightmix soil, and I followed the instructions for the different products.

Other info : 2x2 tent, 2x70w Bionic led at 60cms, 1.5 gallon pots

Fed with tap water only and not pH'ed as advised by Biotabs. I know my water is around 7.8 pH, but I started last grow without pH down as well and they stayed green for all veg time.

Germinated in Jiffy pellets, then directly in the soil with Biotabs products.

Temp around 20-26°C, RH 40-50 %

What is wrong ? From the stretch of one of them, I don't think lightburn is possible. Overfed from the biotabs products? Overwatered ?

Another forum advise me to lower my pH, what do you think ?

Thanks!

Actually after a new check my water pH is around 7.1, even if it's a little high do you think it can be the issue ?

My bad,
I put a Imgur link but I guess it doesn't work here?
Thanks!

These look burned from overfertilization, how much startrex and/or silicium flash did you put in there and how many tabs ?

 

[Fizzback]

I used 30g of Startrex in my 6l pot, 1 biotab, 1 litre with 5ml of orgatrex to soak the pot.
That was done right after germinating with jiffy pellet, so the seedlings were 2 cms tall.

Was it too early? You are supposed to transplant them from small pot, even autoflowers?
Thank you,

Yeah it was too much too early. You can germinate straight in pot if you want to but add the tabs later, i add them around day 10-14 but i also use silicium flash, i think around day 7-10 should be fine(they take about a week to get activated). Same for the initial orgatrex soak, you can do the initial watering with just bactrex in it and no orgatrex and add that one later when they are already well established.

Thank you, I see. I was not unsure about this and couldn't find the info anywhere, I don't think it's written on their manual. Am I the only one who did this mistake ?

So what is my best option now ?
Start all over and kill these three ? In that case, can I keep the pots with the amended soil, start seeds in small pot, and then transplant in the "big" pots ? Or the soil will not be good anymore ?

Honestly i'd start over with a fresh mix myself. And don't overdo it with the Startrex or Orgatrex. Cannabis plants don't really need any food for the first 2 weeks so keep that in mind.

Ok, thanks!
