Are they sick?

[gramsci.antonio]

This time i post when i start thinking that my plants has problems... otherwise they get unhealthy and the growth will compromise... Whenever i'll solve this problem i'll start problem.

I'm under 200 W Blue CFL, Canna Coco A+B, AN root stimulator. Feminized seeds of DP Flo in coco coir.

here's my watering regime:

- How often?

On a daily basis

- How much?

I give 1 liter to my single plant.

- Specs of the water

Sometimes RO water 30 ppm@7.8 ph, lowered @5.2 ph, sometimes i mix water with tap water up to reach 170 ppm.

Previous i used my rock hard water @ 300 ppm

- How big pots?

around 25 liters

- PPM/uS/EC in?

usually 800-1000 ppm

- Ph in?

5.8-6.2, min 5.4, max 6.7

- PPM/uS/EC out?

Around 20% less, 580-800

- Ph out?

the same, sometimes a bit higher, max 0.5 more than in

- Any notes?

I wait to water till some of the top coc start to dry, like when they change color

I've had a MG issue, wich i (think) solved giving the plant 2.5 ml of a solution with 6% of MgO. Is this too few magnesium?

I have to say that i tried to scrog them, but the holes in the net were too small so i switched to something like a kind of LST, just bending the plants to distribute better the light and keep from stretching too much. Maybe i don't treated very well the ladies

First a general look @ the plants: 8 internodes @ day 42 of vegging:

Here's the symptoms:

a) Leaf with a broken white spot. You can't see well from the photo but it has a strange texture, like the skin of your grandma.

b) very dark green inside, fade to a pale yellow on the border.

c) Yellow and brown tips. It thought it was caused by MG deficiency, but up to now i can't say if the symptoms increased. For sure they don't decreased.

d) While training i think a opened a fissure in the trunk. I hope it's not serious. Maybe you have to look carefully to see it.

Your nutrient strength may be to high. I noticed your stems are really purple and I ran into that same problem and try to keep your PH more stable. In my hydro I maintain it at 5.8 it may fluctuate between 5.9-5.7 if I'm not there to check it but I maintain a stable 5.8 always. If your Ph bounces too high up and down your going to have constant problems like I did at the beginning of my grow.

Good luck.
