Same Problem second grow.

[Cont3mpt]

Wondering if someone could shed some light my problem. Below are pictures of my plants (Auto massasin) and the same problem has happened twice now. All through the veg state the plant thrives and then as soon as it hits flower is when I get the problems. Below is my set up and current pictures of my plants. I dont feed any nutrients for the first 3-4 weeks when I start to see a colour change in the leafs and when I started I was giving them 1/4 the dosage and slowly moved up.

Issues started 7 days ago after a watering so looking into it it had all the characteristics of being over watered so I let them dry for 5-6 days until the pots became light again but nothing has changed at all. I am considering just binning them and trying again but I am worried that whatever is causing this to happen will happen again a third time. I have had issues with temp dropping because of the weather we have had recently but this same issue happened back in september when the weather was a lot warmer.

strain : Auto massassin
age: 38 days old
light : 600w
tent size : 80x80x120 (Attic grow UK)
Temp: high 29 - low 19
humidity : 50%
pot size : 13ltr fabric pots
soil: Plant magic 70/30 perlite
Nutrients: 3ml OT Bloom in 2.5ltrs water
Fan: 6inch extraction running negative pressure

PH of your feed? Slurry pH? If this isn't over watering (the droop looks over water but not the yellowing) am guessing there's a pH issue...

I was not ph'ing my water as I was told that growing in soil the PH would do its own thing.

When your using chemical nutrients you need to pH your feeds, and check your water for pH. Is your water city or well? If it city water do you let it gas off? Also if it's city have you checked the readings of what's in it, reason is chlorine will gas off but chloramine won't? I suggest getting a pH meter and a good pH probe the accurate 8 to be exact.

ph is important. Very.
Check water ph. Wait a day or 2. Flush the plants at 6.0 -6.3 clean water

Also test run off.

2nd thing. The yellowing leaf concerns me most. Seems to be spotty. Clip one off and check it really good for mites. That could be another issue.

But as far as looking.
The droop is telling me over water or underwatered. A good bit.
Signs can be caused by a lock out from ph swings as well.

Keep me posted brother. Ill try to help ya save the ladies. Damsels. We save damsels here lol

@Waira is a guru as well with this stuff. If he pops in im sure he has excellent advice.

@pop22 is genius level too.

I am using Old timers nutrients that are organic. My water has a ph of 7.5 right from the tap and I do leave it for 24hours plus before I feed my plants it.

What are the numbers on the bottle?

I'm sorry but. Numbers like 3-4-5 are way to high to be organic, I would check my pH, what could it hurt? Second grow same problems.. and from what I read on there site I didn't see anything about not needing to pH?

So i have just checked one of the leafs and its not mites, I also tested the water that I have been feeding them and it is 7.4. This is water that has been sitting for a few days also.

thanks for your reply mate. This is the second grow out of 4 that has gone bad. On the old timers website they state on the bloom nutrient,

Oldtimer Bloom An organic feed for unbeatable taste and flavour. Feeds plants, beneficial fungi and micro-organisms in the growing medium.

As for not ph'ing, I was advised on another forum that because I am growing in soil that ph'ing would not be necessary.
