Second attempt

I use 16 litre fabric pots if that helps.

Whoever you end up buying from stay away from the Blurple. If the light has a cooling fan instead of a heatsink and passive cooling you are just getting a Blurple.
Another clue is a claim of 300 watts!, 1000 watts!!, 4000 watts!!! and the actual draw from the wall is much less then what they claim.

Hello.
My plant over past few days has started to have very yellow leaves. I am watering with between 6 and 6.5 ph every time. I'm using cal mag and my bloom nutes every watering. Do you think I need to water with just water on the next watering to flush a little? Or is it something else?
Fir some reason wont let me upload picture. Saying too large. It's the larger lower leaves that are worst and seems to be climbing.

We would need pictures to better help

 

[Silverfox125]

Maybe nitrogen deficiency.

Took ages to upload. Hadto reserve it. Seems original was too large?

Watered twice a week with bloom nutes and calmag. peat and coco soil. Holds water. Starting to drink faster this plant us so only just started twice a week watering. I'm not giving it plain water inbetween. Ph is 6 - 6.5 everytime.
Never mist these plants. Dont see much good.
Using the nutes at 1ml per litre. Guide is 2-4ml per litre.
Anything you can advise.

More food? Why are you feeding it at possibly 25% strength?

 

[TheStickyIcky]

Maybe I'm being too cautious on the feeding. Next feed I'll give it full strength. Or go to 50%. As it's taking about 4 days at moment for wet dry cycle should I just go straight to full strength?

 

[InTheShed]

2-4 is a big range relatively, but since they're in flower I'd go to 3ml.

 

[TheStickyIcky]

2ml softwater 4ml hardwater. dunno what mine is. Comes out tap about 7ph.

 

[InTheShed]

Can't tell from that. What's the PPM? The higher the PPM, the harder the water.

 

[Silverfox125]

I’d agree with the above statements. Get her some more food

love the color

 

[TheStickyIcky]

I dont know ppm. Havnt got myself a pen. Novice mistake? I'll grab one tomorrow.
And yes the colours on this plant are beautiful. It's the reason I got the seeds wanted something colourful. Wasnt expecting it to be so intense. From looking at it does she look like she will yield well. There is lots of bud sites. And still a good month and half left from guides.

Are you on well-water or municipal? Most municipal water companies will publish info about their water, which should include hardness or PPM on it.

 

[TheStickyIcky]

Hardness is soft. What is ppm? Its got pages of stuff to do with the water quality.

 

[InTheShed]

You can see if they post alkalinity, but I'm guessing if they say your water is soft then it's on the low side. Do they give an actual PPM range?

 

[TheStickyIcky]

Its saying around 60ppm. From briefly looking online for my area.

 

[TheStickyIcky]

60 or below is what it looks like from a few different sites.

 

[PotChimp]

PPM is parts per million; I believe they're talking about undissolved particles in the water.
If your tent is 2' x 2' and it's 5' tall, that would make the cubic area you grow in 20 sq.' Are you moving an amount of airflow five times that (or 100 cfm) through your tent? Until I started doing so, my leaves had problems that I often mistook for nutrient deficiencies or toxicities.

 

[InTheShed]

I'd call that low alkalinity.

 

[TheStickyIcky]

Ye on moving air no problem for the size of my area. That part I'm covered with. Sooo. What do I do lol?
