First Grow Durban Poison autofem

[BabyRoo]

This is my first Grow
Seeds from growers choice (not great from what I read later) Durban Poison autofem.
Grown in a mix of Coco,peat,perlite 40% FFOF 30% regular bag top soil 30%

Used a little calmagic at week 4 or so and 1 light feeding of diluted FF grow. Watered with compost tea a few times now on day 40 showing distress.

Light watering of epsom salt the other day and some grow nutes on plant 1 to see if that helps, nothing for the others.

I try to pH my water to 6.5 but may be anywhere in the 6 range. Tap water is high at 8 to 9 After it sits for a couple days usually still 8.
PPM of tap is around 360. Water report from city says Cal,mag,sodium run about 35ppm each.

In day 35 top dressed soil with Roots organic bloom and uprising. Also watered with their seabird guano made a tea it is high in phosphorus 0-12-0 I believe.

Thoughts?

First pics early on

so in the last 2 weeks you added this all while using 360 ppm tap water?
calmagic
1 light feeding
compost tea a few times
epsom salts
grow Nutes on 1 plant
Top dressed Roots Organics
guano tea

I’d say that may be a little much. plants don’t look bad from what I see. Time will tell.

You want your medium 6.0ph, what is it? And I agree, probably to much feeding

 

[Mañ'O'Green]

When did you last water? Did you water the entire pot? They look thirsty. What is the temperature and RH?

Are you sure the PPM of your water is 360? The water report shows 195 PPM.

Haven't feed as much as it seems. I gave compost tea diluted once in week 3/ once week 4 / guano week 5 / top dressed organics and water with epsom week 6. Just fed 1 plant yesterday with diluted grow Nute. It's looking little greener today but more signs of distress progressing.

Thinking my soil may be a little acidic, pH in 7 runoff out at 6. Does that mean my soil pH is close to 5. It has some peat and buffered Coco in it.

Water report confuses me as well total hardness near 200 ppm but it measures at 360 and if you add up the cal 37, mag 38, sodium 34, chloride 105, sulfate 41 just those equal 255ppm not sure if that is proper application of numbers. Is chloride an issue different from chlorine not gassing off.

Plant pics were near end of day I'm on a 22/2 schedule the temp drops from 74 to 62 and humidity rises from 50 to 60 it was worse first week with a 20/4 schedule. plants do seem to droop a couple hours before lights out
