I am new to growing. I have a 2X2X4 tent, 1500 watt LED, intake and exhaust set up with humidifer. I have been keeping environment at 60% hum and 78 degrees
Plant is 1 month old. The issue I have is the leaves on my Blue Haze are yellow on tips and have rust spots on some leaves. I have a purple haze plant also in the tent it’s doing great.
I’m very new to growing too. Are you giving nutes already? Have you checked your ph? They look a bit thirsty.
The water is good. At first I was watering and fertilizing everyday. I noticed my plant were droopy one morning. Ever since then my blue haze has looked like crap. The PH is about 7.5 to lower it all I need to do is just add pure water correct?
No you will need to purchase the pH up and down. Add that to water and 1/4tsp per gallon.
Sometimes when you overwater it can affect nutrient intake by the plant. If you’ve been watering every day that is too much. The goal is to water every 2 to 3 days. If it’s not dried out by then, you’ve been giving it too much water.

This was my experience growing 4 amnesia haze autos. My well water has a natural PH of 7.5 and PPM of around 250. They DID NOT like a PH that high. It locks them up and caused what I thought were rust spots. It was not rust it was the plants reaction to a PH it could not tolerate. In addition, this is in part due to hot soil mix I use, they did not like the early application of nutrients (fox farm trio). The odd thing is, 2 of them reacted much more severely than the other two. IMO you are experiencing both situations. You need to decrease you PH to 6.5 or possibly lower depending on your soil. To do this you need a PH pen and PH down. Apera is a highly recommended pen. I use a Dr. Meter PH 100. Discontinue any nutrients. You can see the beginning of yellow tips on the green bushy plant. This may very well be the beginning of nitrogen toxicity. To correct this I was instructed to flush them to wash out excess nutrients.You can use a product like FloraKleen to flush. Flush once with it and a second time to remove it and remaining nutrient remnants. In addition to a PH pen, you should also get a TDS / PPM pen. To grow successfully and monitor the health of your plants you need both instruments. Welcome to the world of chemistry and plant pathology.
The corrective actions I took saved my plants. Most importantly it taught me I need to know what is going into the plants (PH and TDS wise), and also what is accumulating in the soil by checking runoff.
I created a couple of topics about my amnesia haze autos if you want to check them out.

Thank you for the info. I will try to fix my PH.
Checking run off water is a good idea @beardless
Pure water? As in distilled or Reverse Osmosis?
Neither of those have any dissolved solids so no need to adjust PH when just using them. When adding nutrients to that type of water after adding you will want to check PH and adjust PH to around 6.5 for soil medium. If coco medium adjust to around 5.8 and then feed.
I don’t use PH up or PH down chemically derived adjusters as I don’t want to negatively affect my soil critters…bacteria and fungi.
I use this for lowering PH as it doesn’t harm critters and is organic.
It’s cheaper too
This for PH up
Or earth juice products…which are the same things just labeled brand name etc.
Don’t overwater
Don’t feed every time unless coco medium
What medium are you growing in?
