This one looks like it didn’t like the level of nutrients you gave the other girls. I would give her just ph’ed water the next time you feed the others and see if she perks up for you.

Magnesium - Nutrient problem
Do I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly. The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1. Has anyone the same problem? Thanks!

Yellowing of top fan leaves
What is causing yellowing of the top fan leaves? Started to happen to a plant that I broke by accident during LST. However around the same time I upped to 2ml/l and moved the light a little closer. My ph has also been high (fine now). No idea which one could be the culprit

New growth gets lighter in color
Looking at the pictures you can see new growth on both plants is getting lighter in color each day. I’m thinking nitrogen, maybe? Complete day by day photos are in the diary. Thanks

Nutes in flower
Anyone have any feedback on running high ppm in flower with RO water? Does SLF-100 help flush unresolved nutes? My first grow but I think I'm blowing it, please look and tell me what I'm doing wrong.

PH all kinds of fucked up!
Urgent update. So it turns out the issues all alone where the soil ph which after testing it was PH 3.2 😳 I have flushed with ph 6.8 water and then added some epson salts bringing the final ph back to 5.6-6.2. I then topped the pot with new fresh compost. Will she survive?

Nute Lock??? What would you do?
i'm looking at the leaves and seeing some different types of nute defficiencies and thinking it could be nute lock. So i've flushed to see what happens and will investigate afterwards. Am I right? would you guys flush this from now and for the rest of flowering??

Need help identifying the deficiency here
I just started seeing some kind of deficiency on the lower leaves of my plant that's still pretty young. Can someone please help identify? Just tested the PH and it's at 6.4. I'm not seeing any spots on new leaves. Do I ride this out? Do a flush? Appreciate any advice!

Yellowing too soon?
What do you think about the yellowing on the 6th week? The npk of the soil i use is 9-2-2. But its the king of yellowing when she needs more N. No dark spots, no burnt tips. This would be normal maybe on the 8/9 week i think.

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

Auto Ultimate feeding problems.
Why are my plants burnt at the top (new growth) but half way down the plant it has nutrient deficiency? How can a plant be hungry and nutrient burnt? Before you say it... Yes my pH is correct, yes my ppm is lower at run off. Temp is 28 celcius, 65% humidity, week 6. What is it???

Spraying the leaves
While I was checking my plant I saw these “black stains” like the plant is “half-bitten/scorched”.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

Purp stalks, weak leaves.
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.

Sugar leaves affected- 6th week of flowering
If you have a look at the 7.5lt one, the sugar leaves affected by a deficiency, I was thinking of CAL... Considering I'm pretty close to the harvest time, shall I simply flush and switch to plain water to be on the safe side?
