How can I solve?

[Bluey]

Problem solved. It was something growing in my tank, likely algae. For anyone interested rising pH, dropping EC and more and more pH down, like way to much was required to knock it back down.

Nutrient tank stability issues

Tank is a light proof 30gal or 120ltr tank. Temps pretty stable 70 to 72⁰F or 21 to 22⁰C.
Growing in coco so 2 part quality flower nutes plus a cal/mag additive. I'm week 6 to 7 into flower
Using rainwater. Have only received less than 2" 50mm of rain in the past 3 months but had recent downpours over the past couple of weeks totalling 1 to 2".
I dont run air stones but do have that option. No algae in tank just some minor sediment in the bottom and minor accumulation of salts on the sides above waterline from the evaporative process. Ec of water is zero.
I add my 2 part nutes with vigorous mechanical stirring and then cal mag to bring it to an EC of about 1.6. I have had to pH down lately but not much, from around 6.8 down to 6.2 using citric acid.
I found my pH is climbing up. After 1 day it will go to 6.65. After 4 days up to 7.1. The EC is dropping at the same time. After one day from 1.6 to 1.3.
I am correcting this daily atm but I need a better strategy as I am away from the grow for 4 to 6 days at a time atm and I am at a point in flower where trichomes are beginning to form...a critical period.
Any suggestions please.

Cut the bottom leaves off that are on the dirt. You need to train the plant. It's growing too tall and you have large node spacings which indicates insufficient light....remember light is food for your plant..your leaves look pale in those pics and are flat looking so as abovevon that one. Good luck

I've been told those cabbage looking leaves are from too much nutrients

Hi, this is thw whole plant. I don't know which strain it is..

[SoOrbudgal]

Wehee we need a wee bit more info about your plant. Is it Auto or Photoperiod, age of plant, soil or hydro, type of light and distance from plant. And a full plant pic would be good.

[Bluey]

Without any info apart from the pic Wehee I'd say well and truly overwatered...early veg right?

[Wehee]

Hi! First timer here, and I was wondering, what's up with my plant?

[Bluey]

There is some amber/golds in the first pic...possibly some in the background of other pics. Can you see amber/golds on it? I really suspect your plant is almost or is done...do you know if she's drinking much?
Pics of buds would be great..show us any problems..check for loose buds

[ChubbNugg]

dont smoke the rayon fiber

[SoOrbudgal]

Is that a leaf you took these pics of ? It's not ready in my book got a long way to go weeks.

That length of time from 12/12 is all we need to know and is pretty much what I suspected. Like Bluey says, you're at the end of your grow and that's just what cannabis plants do at the end of their cycle. They've been in flowering stage for about 7 weeks, and most plants are harvested between 8-10 weeks so you're nearing the end of this grow - good job making it through!

Just like corn or soybeans (Midwestern boy here!) in the fall, they turn brown and dry up and then it's time to harvest. Your plants are doing exactly what they are supposed to do. You'll also notice that they'll start drinking less so be careful to not overwater.

Start looking at the trichomes under a magnifying glass. You'll see them starting to turn cloudy and then amber. There are different guidelines when it comes to using the trichomes to determine readiness, but in general when I see about 10-20% of the trichomes turning amber, that's when I know to harvest. Of course, the best way is to take all the factors into account:
- Length of time in flowering
- Are the pistils orange/brown/amber and curling in?
- What do the trichomes look like?
- What is the overall activity of the plant?

It looks like your pistils still have a little changing to do, but you're getting close to your harvest window. As the days continue, you'll see those start to all turn orange/brown/amber and they'll shrivel in. Continue to be patient and keep notes on how the plant behaves towards the end of flowering so that on your next grow you can adjust your care of them. It looks like you have some pretty healthy plants and you should be pleased with yourself!

You're at the end of your grow...it's giving everything to the flowers, that appears to be what's going on. Can you get pics of the trichomes or pistols if you can't? Heat may not have helped but 29⁰C should be ok for most..it's at the high end of ideal
