Droopy Pale Yellow-White Leaves and Stopped Growth

Hello Everyone,
Having deficiencies on my two month old auto fem blueberry, very slow growth, pale white/yellow older leaves, overall plant is turning yellowish, ph is ranging from 5.5-7.0,
watering once every two days, keeping the soil moist but not wet. Using natural sunlight, it is getting direct sunlight around 5-6 hours a day. Grow medium is rich nitrogen, phosphorus and potassium. Added extra nutrient solution four days ago that includes calcium and zinc. My very first time growing cannabis, though I am experienced in botany but this little lady is pushing my limits. I am setting a dark room with hps lighting/venting though it is not going to be an advanced room. My plant is almost two months old but looks like its just been a couple of weeks and it started developing trichomes(auto fem). I will appreciate if I can get any help diagnosing what the problem is, I am suspecting it can be more than one. I have had extensive research about cannabis growth and deficiencies but what I had read confused me even more. Any help?

she looks pretty much dead/done to me, I would kill her and try again

Since I am going to use the same grow medium and nutrients, a new plant might have to go over the issues again, I am not interested in getting any harvests on this, not very possible at this point but I am trying to increase my knowledge of cannabis growth and getting a better insight on plant-care for future tries.

you really want to let the medium dry out in between waterings. That little lady is a goner better luck next time

I see, thanks for the link!

Don't follow crispy fried youtubers like that guy in the link. His plants look like crap.

What is that you're growing in? It doesn't look like soil. And you need a balanced nutrient that contains all the micronutrients. What nutrients are you using?

That 2 month old plant looks like a week old seedling. Something isn't right but you really haven't provided enough information regarding what that medium is and what you're actually feeding. But that plant is not growing into anything so you need to make sure your next one does better.

Trash it and start over with better soil......one that includes perlite preferably.

Two months !? You should have trashed it and started again 1.5 months ago. Never seen anything like that. Sorry

Is it just me or did that plant try to flower? Amazing such a small plant would but it looks like she did what comes naturally even if she was only a infant.

What the hell is that thing? It's cotlydons are still on and it's flowered... 2 months old? A plant should be bigger than that after 2 weeks..

Yes, it's two months old. Yes, its trying to flower. Medium is a generic plant growth soil for indoor/outdoor plants, only written on being nitrogen rich. About nutrients, I use a nutrient solution I wrote above. Cannabis specialized nutrients/soil are not sold in my country, and almost impossible to find organic nutrients for plants in my town also on the internet. I am suspecting it is the lack of proper light and perhaps the soil since growth can be halted with many factors, and nutrient deficiency is easy to spot on (on other plants at least) though it's been only 10 days since I observed any visual factors. My soils' moisture hold is quite long, and I observed two other saplings root systems yesterday. One of them was rotten, the other was holding on but weak. I think it would help to check out this little ladies roots.

2 months old + auto? You'll be lucky to get a gram of smoke from that. Better to start fresh. Just being honest mate.

That ph is a real problem for any soil. Should be higher.

Visually, there's absolutely jack in that soil. You need a better quality one, or mix your own. (it's lacking in organic matter)
Test the soil's ph before planting. Ideally you want it to be about 6.5.
Your water shouldn't be any lower than 6.5 for soil. I would personally leave it neutral.
If you have rot, then it's been consistently far too damp. You've been watering too frequently, or your aeration and drainage is not adequate.
Your acid water / soil isn't helping with root rot either.

I recommend starting over with photo period plants, instead of automatics, in new soil. They'll be less forgiving if your soil isn't good for a start.

It looks like you are growing in pure Coco Coir which is inert and has no nutrients.
Also, you dont need special cannabis nutrients to grow good cannabis, stuff that works for other plants also works for cannabis.

Click to expand...

Was it one of those large expanding blocks from your local hardware / gardening supplies?
How did it come?

If was intended for garden bed use etc, with added slow release nutrient, they're always advertised as a soil type product, but they're not.
They usually run hot and are often dirty too. No good for young plants. (i've seen above 2.0 ec using them, after expanding)

Sorry for the late reply. They are doing okay right now, fixed the yellow/droopy leaves with watering them less. Next time I'll be veeery careful with the soil, and ph, and watering. It's good to know that I don't need any special nutrients/soil to grow good weed. For expanding blocks question, yes it was. I suppose I'll be pickier with the quality of soil next time. By the the can natural sunlight of approx. 5-6 a day, can drastically affect the growth of my plants? Or the major problem was the soil itself?(plus nutrients, ph and watering)
