Twisted leafs, stunned growth

Hello, i have 4 ladies in my tent

4 autos, forgot the strain names
But maybe important fact is that the one who suffer the most, the one on pics are diffrent strain than the one which is flowering right now

90x90
400W HPS
Full ventilation with filter, passive intake
24-30 Celsius
40-60% Humid

Biobizz light mix
Biohumus for veg + Asahi SL once a week

I dont remember how old are they. But if i remember right the flowering one is at 45days, The one next to her is not on the photos, just stunned growth and the 2 showed on the photos are like ~~ 25 days old


Watering PH is 5.6-6.7( usually 6.1)
PH from the flowerpot stand is 5.7(checked only one but i used same water for every one of them, only the flowering one get some mineral nutrients last time with other bottle)
I tried week ago to use a organic fertilizer 6-6-6 NPK, nothing change,i used 125%dose

here's your sign

@teddy bonkers it was 18~~ day of life, and they already showed this symptoms, and there is no nutrient burnt, i know it might look like that on photos but its not. So what you propose me to do? Flush it with 18L of water? Thesse are 9l pots

looks like too much Nitrogen. I would just use plain phd water for a couple times

Im trying to do that but the pots are usually heavy, they dont drink much, i water 750ml per 2-3 days, and some water is staying on the flowerpot stand, but not much and for no longer than 30min

don't water till the pot is light. MJ doesn't like it too wet, but also not too dry. if that makes sense.

@teddy bonkers sorry for calling but you were only one responding before and i need one more advice from you

I did what you said and plants started growth, one quicker the other one not much. And the other one started to show what you suggest i think. Nutrient burn but i need confirmtion. Also i spot some purple leaf edges on the quciker one. And both of them showed preflowers yesterday.

The one with nutrient burn i water today with 1L of water(it was hot in my country and the HPS400 is doing the work with 29 celsius in tent)

So to cut the bs

TLR
Both started to flower
Yellow tips
Purple edges

Last 2 waterings with only water PH 6.2

Nutient overload, causes lockout of nutrients. They should not be so dark green. Backoff on nutrients, and get a bloom feed nutrient now that its in flower.

@lime73 so what you suggest to do now? I will for sure wait at least 3-6 days with nutrients for bloom anyway. Now flush? Wait? Water with 2-3 liter? its 8L pot

I would use just water, for next few feeds...then once it starts getting a bit lighter in color and twisting new growth starts growing in normal, then id start to feed bloom nutes.

^^^ some good advise there. forget about using any nutes till your new growth looks really good.
