Need urgent help

Hi people,
I'm a first timer running an auto euforia under 125w qb in a 5l airport and I just can't figure out what the hell is wrong with the plant. I'm feeding ghe trio +aptus calmag + just added some dry coral powder into first layer of the soil.she sits in plagron batmix (soil ammended w/ guano)
I'm currently at day 48 and have been trying to deal with many issues the last 4 weeks already(check pics too):
- Droopy leaves without over- or underwatering
- all kinds of spots from white to yellow to brown to grey to red stems
- slowed growth /development

Im always at pH 6,2-6,6 and flush every third to fourth watering.
Do have any idea what else I could do to get this plant back on track??
Thanks,
DrNoob

Looks like a watering issue to me. Is the fan on the plant all the time? I might try moving that so there is air movement but no direct stream..

Watering issue in what sense? Too much or too less?
I alwys wait 2 days till the medium dries out.
And yes it's direct stream but it's only a 5 w fan.

When it turned into preflower on day 25 I fed: micro .75
grow .5
bloom .5
Always between 2 and 3 litres so that I have less than 10% runoff
Since day 39 I feed as ghe recommends for flower (thinking they were underfet)
.8 micro
.7 micro
2.1 bloom
All in ml per litre

5L isn't a very big pot really, not a lot of watts in light either. Less water the pot will hold and likely less water the plant is drinking.

If you're feeding per the recommended and every 2 days, i'd say you've likely overdone it.
Maybe some salt buildup in the pot?

Any watering in between, or feed every time?

Haven't used coral powder as an amendment before. Doing some digging now, it's stated 1lb of coral powder, is eqaul to 500lb of ag lime.
How much did you use?

Really not much, maybe half to one tsp.
I know the pot is not big but I don't have more room. Yet it has become quite a big bushy plant. I flush every third watering so there shouldn't be any salt in the soil.
The point is it looked like that already b4 I raised the nutes in preflower.
My last guess would be that the soils ph is too high and that's why there is lockout.

"Coral Calcium" is the ag amendment I can find, when putting "Coral Powder" into google. Find out if yours is the same stuff.
If it's the same thing, you've probably put over a pound's worth of lime without realizing.
That's likely what's raising the ph, if you say the ph is high. How have you been measuring the ph of your mix?

It's a really nice sized plant for that size pot and light.
I find generally plants in smaller pots need less ec, but watered / fed more often. You may well be supplementing the correct amount, just doesn't look that way. Someone who uses the same nutrient will likely be able to help you more here than I can.

I would find out exactly what sort of coral you have, how fast it activates and whether it's started activating yet, bu measuring the ph of your soil, using a soil sample.

Thank you once again Aussie, i can try test the soils ph but I have no device to do that but indicator drops. Maybe I should also water at 6,0 for some time

That's alright man. Don't worry about flushing water through, there's probably not a lot you can do. I'd keep the water closer to neutral, imho you're not going to make much difference to the ph of the soil with water. Don't worry about changing it.

Plain water and light feedings.

are you applying a good microb environment so the girls can up take nuits.feed the soil not the plant .feed the soil and the plant will take care of itself.microbes also help stave off issues like ones shown.this is just how I do my soil,and have great success.Mammoth p would be a great place to start.check it out

The coral powder was mixed w/ mycorrhiza but I didn't use much.so the answer is not really. Mammoth p Sounds actually awesome but I'm kinda stingy at this stage of my grow cause I already quite high on budget and I feel like b4 I invest another 50 bucks for Mammoth p id rather try stuff that's not that pricy..
Got any alternative to spice up microbial activity?

Looks like magnesium deficiency with some nitrogen deficiency as well to me. If you're already using something for cal mag it could be that your pH locked it out. It would be awesome if you could get a pH meter and test the runoff.

I do have a pH meter!
I can test the runoff but I don't know how efficient this technique is..do have experience with this?

I don't have first hand experience and I'm very new to growing, but I know that testing your runoff pH gives you the pH of the soil. I know that the leaves look like that with a magnesium deficiency. I know calcium is only taken in by the plant at 6.3 pH. I'm not sure what pH the magnesium or nitrogen get taken up at. Always proceed with caution and take this as advice and not a mandate as to how to fix your situation.

yea doc I also use SUPRE MYCO TEA made by SUPREME GROWERS,one teaspoon per gal of water.it was 25 bucks,it has beneficial bacillus,mycorrhizae and Trichoderma.this is what I use in my soil mediums.best of luck and good morning

40cm x 40 cm x 120cm
30cm from plant
24/7 cycle
25°C and 50% rh
strain dp auto euforia
The 125w QB (single board I assume) is ideal for 60cm x 60cm at 18" above canopy, you should be dimmed down to 50% at that height in that space.
The 24/7 light schedule only compounds the problem. Plants getting way more light that it can handle all day, every day.

Not saying you haven't got other things going on, but pretty sure if your running that light at 100% in your circumstances its going to fry your plant and make you chase your tail looking for a solution, with symptoms of every deficiency you can think of.

knock it down to max 20/4, dim it a lot, raise temps a few degrees if its possible and hope she finished ok.
