Have you checked PH of water with nutrients in it?

 

[Teleon]

I usually double check the pH with my pen and the drop test... But I noticed that the pH goes up again when I have some left over water... Means I water them on the evening (pH 6,5 temp 20-21°) and in the morning it's like 6,8-7...at the same temp.

When I mix all together I let is sit for at least 2h and give them a swirl every ~30mins. The ph even raises in this stage, so I usually add some pH - to get 6,5 and wait a bit than I water the plants... Is that wrong what I do?

Update Time

Day 9 of flower, they are beginning to flower!

Gave them some nutes today, they beginn to need more and more water ^^

All in all they look okay, I think I should begin pruning somehow, but I'm afraid....

 

[CraZysWeeD]

Looks better and better. They should have had time to adjust for the new light now as well. I would cut away all the big fan leafs but that's me. Maybe not all at once! Take a few lower down at first. Give it a few days and take away some more if you feel like it.

 

[Teleon]

Thank u

Yeah, I will start with the lowest...slowly


Btw, I think I know why the leaves are turned, might be heat stress, that could be a good explanation?

 

[CraZysWeeD]

Sure what's the temp slightly over canopy?

 

[Teleon]

Can't tell exactly, will tinker tomorrow but I raised up the light a bit - and I think they also needed to be okay with the light change ... the new light has nearly doubled the lumen.

 

[CraZysWeeD]

Yeah they are very intense these new leds, no wounder out plants show signs of deficiencies.

 

[Teleon]

The cal/mag was with the "old" light.

Btw, I really will update the lamp, as I said - for early veg 3x 30W (1x warm- and 2xcoldwhite) and when they are bigger, switch to the 200W (100W warm- and 100W coldwhite)

 

[CraZysWeeD]

If you think you are out of the woods regarding cal/mag you are wrong. I still have trouble finding the sweet spot for them. If I add 2ml/L with Calcium the EC goes through the roof. Last time I mixed I gave them 0,5ml/L and now the EC is good. Magnesium is no trouble giving 2ml/L regarding the EC but the pH wants to dip with it. Now I'm at 6,3pH and 2,3mS. Hoping they will turn greener but they still look pale in the new growth accept Ww she is the greenest of them. I think I will let her swell for a few weeks more before I take her. She should be done by now but I was hoping she would yield some more. Looks now like 50-60g maybe. Optimal is to get 100g per plant. The last grow the average was 80-100. Some gave 120g per plant. So that's where the aim is for.

 

[Teleon]

Yeah I also still gave them cal/mag but only a tiny bit - yesterday 1ml each on 4L water ^^

2,3mS??? I'm @ 1000-1100, but not more at the moment, thought not to go to high. Maybe I should give them a bit more. Just do 50% of the nutes-plan from BioBizz.

Do u have a barrel where the water + nutes are in? Oo how do u do that?!

On my 3 Lady's is clearly to see that they are all slightly different...The late lady is the greenest, the other two are still a bit pale, but I gave them grow and flower nutes yesterday, so we will see.

And it's fun to see the flowers forming, everyday is something new to see

 

[CraZysWeeD]

Ya 2,3ms/cm.

I use a self watering system, Autopots. I have a 47L tank which I mix water and nutes in. Then a valve in the pots regulate optimal watering for them. The pots house a air system, air-dome, which pumps oxygen in to the root ball of the plant.

Now you're getting in to the fun part of the growing.

 

[Teleon]

Sorry I meant 1,0-1,1mS/cm - was afraid of going higher, but the first and the second are still pale - and dont look that green as the late one does.

Ah okay, I see - looked up those Autopots...hmmm, maybe also an option - but i dont think that the water reservoir fits in my tent, otherwise it wont work.

 

[CraZysWeeD]

That's the down side of the tank, it's huge.

Look in the scans I gave you on plant issues. Look at the picture regarding Nitrogen. That gives purple stems and pale leafs if missing.

 

[Teleon]

Yeah I also found this - there is a lot of deficiencies and co - it's also in german.

I give them tomorrow again the half dose of the nutes, after this watering than water just with water and than have a look, or what do u mean?

 

[CraZysWeeD]

I noticed another thing when I brought out the plants in to more natural light. Then the signs don't show as clear and they looked a lot more green than inside the tent with all that light.

 

[Teleon]

That's why I use the flash now on my camera then u see the colors a bit better.

 

[CraZysWeeD]

Ah great! I used to take photos during the dark period. Then the flash lights up the crystals nice.

 

[Teleon]

right after the light time? or before the light went on again?
