what cheap way would u recommend for testing ph, I'm not spending the cash on meter.

Unfortunately I have no experience with Autoflowers, but I'll try to help how I can. I'm seeing a wide variety of "deficiencies" in those photos you provided though. I say "deficiencies" because you definitely have lockout that is the result of over-watering, and the flushing is only going to exacerbate the issue. You only want to flush your soil when you have excess, but this isn't the case here.

How often are you watering? Stop watering immediately, I'd give it at least 2 if not 3 days before watering again. Let things dry out for a bit and take it easy on the nutrients for a bit.

If I were in your shoes, I'd stop watering for a couple of days at least. Use the lift test. Lift your pots and feel how heavy they are, that's how they feel when fully watered. Until the pots are significantly lighter to lift, you shouldn't be watering. Once the pots are light to lift, you can go ahead and water but take it very easy. I definitely wouldn't be using nutrients for a little while either, at least a week.

I'm 99% sure you're over-watering though. The biggest sign of over-watering is lack of nitrogen for the reasons I outlined above. You're running out of nitrogen because the over-watering is turning your soil anaerobic, allowing anaerobic microbes to thrive in your soil. They are eating up all the nitrogen in your soil and are converting it into ammonium nitrate gas. The result of this is not only a N deficiency, but the resulting gas from the microbes is also causing extremely acidic soil conditions. This is why you're experiencing lock out. Once the soil starts to dry out and return to normal the anaerobic microbes will die off and you can start to recover.

HTH.

I agree

I agree for the most part. pH issue, most likely due to watering habits. Over water.

Under watering can create problems as well. Peat is the worst for it. The soil dries and becomes hydrophobic. It won't absorb water. I've had it happen on an outdoor plant. Center of the root ball dried and would not take water.

A drop of dish soap will help break water tesnion if it does become hydrophobic.

A good draining soil can be watered frequently and not cause harm.

Normally, when i water the leaves are pointing up I thought when they r like that is a good sign, what should I be looking for an underwater plant, dropping leaves?Because I not having those n the leaves are always pointing up and it grew quite bushy..I m really puzzled what is the problem and what to do..

whitebb2727 said:

Pointing up and they are fine. Sounds like watering is fine.

Probably just pH and amendment issue.

My ph is always spot on because I use a ph pen, but I realized from where it comes my problems, it's pests!I found out some scales and several thrips, it explains the silver in the leaves and the black dots is sooty mould..Apparently, the pests excrements(honeydew) in contact with the leaves creates this black mold... I wasn't paying enough attention to my babies, I was checking them outside the growbox where I don't have enough light, but after finding a dead fly in one the leaves it led me to the pests..this explains the problems I m having the stunted and twisted growth, necromancy in leaves since this bugs they are like vampires that suck whatever they CAN but mostly they r looking for sugars in the flowers..now I m trying to figure out what I can do to take care of all of this issues..

pH of water is different than pH of soil. Mix equal parts soil to dionized water and test the pH of the slurry to.know the true pH of your soil.

I don't doubt pest are part of it. The twisted grow is from pH issue.

How are u sire your PH pen isn't broken?? I had two ph pens and store them both same way, but one went off..

Leandrobcool said:

Cool idea, I didn't know you could test the soil ph like that, sure will do that later.

When I flushed the plants last week, I tested the ph of the first run off water n it gave 6.1, is this reliable?
But I did have a rootbound do u think that could explain the ph fluctuations?

In between I have this "things" growing, any ideas What it is, or Why I have them?

whitebb2727 said:

It can be but it can also have you chasing your tail. Run off pH isn't always accurate.


Being root bound can cause plenty of issues. pH of soil swings as it dries to allow proper nutrient uptake. Being root bound they won't take as much water and hold it as long.

So I tested the slurry's ph n it gave 6.1, probably like you say the problems i had with ph was because of the root bound, however since I sliced some of the roots it improved towards that.

I think that slicing, plus the flushing ( and the lollipoping starts to pay off, because I finally start to see some flowers forming, what it misses is to get rid of the thrips and that sooty mould, any advice on that? I killed some with tape, but they r so tinny that it's impossible to check all plants n kill them all

I tried a water solution with iodine, but it didn't kill them, maybe I need to increase the dosage to "burn" those fuckers!!

Looks like you've got seeds in your compost/worm castings. Probably tomato.
I used fresh worm castings outdoors and had tomatoes growing in all my pots.

If it is root bound I would slice the roots like you did and get them in bigger pots. They will need room for flower.
