Yellowing on leaf!!

[John1419]

Hi guys thanks again for all your help. So, I'm growing in a 3x3, Optic 4..1st time Grow. Suite Leaf Critical Purple (MEPHISTO) is at 5 weeks old Monday. She looks good to me all except a few of her leaves have developed this yellowing. Can someone please tell me what this looks like to them and if I damaged her and what I can do to fix it.

Thanks, can you also provide additional information such as how you feed, etc? I think there is a sticky post from an admin for the info needed

There are a lot of reasons why this could happen. It will narrow it down

Problem: yellowing of a few leaves

Medium/grow method: OS/INDOOR 3x3 Grow tent

Feed: and supplements used: suite leaf, roots organic bar guano (1 time and gave too much I found out later so stopped giving it)

water source: distilled then filtered tap

Strain/age:5 weeks Monday 7/29

light used: Optic 4

Climate: in tent approx: 78F 66%

Additional info: Also, was reading extremely high PPMs. Still kind of don't understand how they work. I now know my water already has PPMs..which was one issue..but even so I followed exact directions to make up her food and the PPMs still run really high. So not really sure on how to get them under control.

It looks like nute burn. Water her with plain pHed water and let a significant amount of water through.

Ppm is a confusing yet simple process. It took me for a loop as well.

Overall it measures the minerals in the water.

What is your tap water saying for ppm? (Before nutrients)

Sometimes tap water ppm can be too high and you may need to use a different source of water (ie: store bought)

After you flush her with pHed water, dial back your nutrients and you will be fine.

Its probably where the plant is young, it requires far less than an older plant

Most will start with 1/4 strength after it enters veg stage (from seedling, and not coco or hydro). Now is when you would increase to approx 1/2 strength and watch for any deficiency to bump it up again

The ppm in my water is 214. I also have some purple and going on on top of all my stems is this fine ? my last runoff ppm was in the 2000s
