Hello. I have a question about the soil im using. I hope i can finally sort this out as its starting to become a nightmare after using it for some time. I had mix results with it so far. Everytime i get in flower i start to see some problems. But before we analyse the problems im facing i want to clear some things in my head first.

So the soils technical character is like this:

Compound of black peat, long-term fertilizer, Perlite, Agrosil® and lime.
Density = 430-450 g / l.
Water retention index = 70-85%.
Organic content = 80-90%.
PH = 5.0 - 6.5
Compound content: 200 - 450 mg / l
Fertilizer, Compo Fertilizer Wands.
Salt content (KCl) g / l: <2,5
Nutrient elements in mg / l:
N = 200-450;
P 2 O 5 = 200-500;
K2O = 300-550.

What i want to understand is what ph i use for watering?

Organic contect 80% means its treated as soil with 6.5 ph?

What are you feeding the plants for nutrients? Soil fertilizer only lasts so long. It would appear to be considered a soil product and you would water at 6.5 pH, but not 100% sure.

So i should stop watering at ph 6? Water with 6.5 and see what happens. Some plants are looking good for 25 days into flower. They look kinda hungry and have vigorus growth and bud develop with. But a lot of the plants have dark green on leaves and they are smaller. They havent grow stretched much since flower mode on. One of them presenting brown spots on fan leaves and some necrosis of leaves which looks like phosphorous def.

400 ppm of megacrop
180ppm of terpinator
30ppm cannaboost
Bloom Ph down to 6

I given plain water now and i will wait for a week to see what happens

Don't worry too much about ph in good soil...anything between 6.5 and 7.2 plants will thrive.....this includes feeding with good nutes.

So its better to water at 6.5 instead of 6?

Theres something im doing wrong for sure. Half of plants have dark fan leaves color and one of them has signs of phos def. Also some didnt stretched much and also there is space between the nodes and buds between them.

I will give 6.5 after all and hope for some improvement. I will wait for the deep green to become more light green before i give them a light feed.

So after all this soil is not soilless and its better to get the soil ph?

Anyone else you can tag and get more opinion on this?

For reference this is the soil characteristics:

Compound of black peat, long-term fertilizer, Perlite, Agrosil® and lime.
Density = 430-450 g / l.
Water retention index = 70-85%.
Organic content = 80-90%.
PH = 5.0 - 6.5
Compound content: 200 - 450 mg / l
Fertilizer, Compo Fertilizer Wands.
Salt content (KCl) g / l: <2,5
Nutrient elements in mg / l:
N = 200-450;
P 2 O 5 = 200-500;
K2O = 300-550.

If I may add a bit of detail? TY. Most soil mixes require 6.2- 7.2. Lower end for photos. Upper end for auto. Always drift your ph in the range. And increase PH as you flip or start flowering on auto. If you end up with build up and creep? Which I suspect. Just a good flush with distilled from the jug will set you back to safe.

Best wishes and amazing outdoors to all.

You're plants are already in a nutrient rich soil and it seems like some plants have enough or to much by the dark green leaves you mentioned, and also some plants don't have enough nutrients by the deficiency you mentioned. All strains/pheno require different needs. Just water with 6.5-7 ph for now and only feed when the plant needs it.

These photos is from the 1 plant with the weird symptoms.
The first 2 photos look like phos def.
The photo 3 and 4 look like calcium def.
The last 3. Photos lool like tip bending down from excess nitrogen.

Only this one atm has show something bad.

Looks like you thought yourself into a corner. Too complicated to get balanced. Amongst others. Also I see pests in my opinion. You can save it. But I'm out. K.I.S.S.. None of this fun then.

Best wishes.

So you see pests? Under the leaves? Inside root matrix?
