Dutch Passion Slooooow start

[KonopCh]

Soil is Plagron lightmix (pH 5,5-6,5, EC 0,8-1,2), I didn't add nutes. Only Canna rhizzotonic (1-2ml/L) which has NPK 0,6-0,2-0,6.
pH in check, EC in check. Lights at proper distance. Really don't know what's reason for slow start.

Aaaand what is this now?
She's standing, so she have roots. But no leaves. pH water, paper towel method, 25°C, dark.
I am really not pleased with DP anymore!

I'm afraid it's not the seeds that're causing your problems buddy, that right there is the result or something being wrong with your grow medium. Looks like something might be up with your soil? Sorry I can't help more, but I can tell you that it's not the seeds.

 

[KonopCh]

Soil is new and unused, 2 batches.
And other 2 seeds are healthy. They're in the same soil.

I've grown DP seeds for years now, almost exclusively. Done both hydro and soil. Only time I ever experienced anything like what you've got there is when I had dodgy Plagron Light soil mixes.

Never experienced anything wrong with any of the DP seeds I've ever bought, seeds don't just attempt to grow and then give up.

Also, why are you using an EC meter? That was one of my worst mistakes when growing in soil, you don't need to EC nutes for soil grows. Ideally you shouldn't really be using any nutrients until it shows it's first few sets of leaves, as Plagron Light contains enough nutrients. Just water it every so often with plain water, then start using quarter strength nutrients until it's big enough to handle half strength, then 3/4, then full strength towards the start of the flowering stage.

Also you don't really need to pH your water either, the soil mix is meant to contain microbes that will raise or lower the potential for hydrogen (pH) to the right levels

Yes, I follow guidelines like you said. First 10-14 days only plain pH water. With root stimulator of course.

Hmmm... interesting about EC and pH, didn't know that. Could you explain more or post some links for "night reading"?
I use EC meter to measure strenght of nutes. Young seedling 1.1-1.4, then after 3 weeks I upped to 1.7. Then starts flowering and I upped to 1.8-2.2 - depends on strain. So without EC meter I wouldn't know what is strenght of nutes. You know, you can easily burn them if you go with strenght written on bottles.

And about pH... You saying Plagron Lightmix contains microbes like soil outside in garden - so no worry about pH? What if nutes lower too much water pH - let's say to 5.1?

You can use your EC meter to get readings of the nutrients you're putting in to your water if you want to, but generally I found I had best results by just going 1/4 recommended bottle amount for 2 weeks, then ½ feed for 3-4 weeks, then 3/4 for 2 weeks and full strength to finish it off before a flush.

It's not easy to burn plants to be honest, unless you're saturating the soil with high concentrations of nutrients. The general rule is less is definitely more Some people confuse pH problems with over feeding. You'll know if you're over feeding when the leaves turn crispy, yellow at the tips and red towards the middle. Everything else is just pH imbalance

I haven't got any materials to hand that explain EC and pH with soil grows. I was going to say 'check out my earliest grow journals' so you can see the effects of pHing soil first hand, but AFN moved servers I think in the last year so most of my old content is now gone

My first ever soil grow got featured on the Dutch Passion website, and as you can see from the photos, it was suffering from some pH imbalances towards the end. That was because I tried to pH the soil not knowing that Plagron didn't really need it. My two/three subsequent soil grows also suffered the same fate, and I even tried using Epsom salts. That didn't help either, it just made my soil nasty and crusty.

Try Googling phrases like 'plagron light cannabis' and see what others have said about it My personal recommendation would be just water it with non-pH'd water until it gets a bit better, or scrap it and set up a new pot and try again with plain water for a few weeks. When you start feeding, then you can pH the water Again like I said I'm a hydro grower these days so my knowledge of soil grows is a bit sub-par, but I'm just going off experience with the same soil. There may be other folks on this forum who know more about it than me

@BillyWu thank you, I appreciate the answer.
Tomorrow I will look at your journals.

We would say (not in english): more heads knows more.

I sure hope you get it worked out i just grew their night queen she was awesome wish I had ordered more from them I will be ordering more on next order.
