Nutrient Burn During Flowering

I am in week six of flowering. Several buds have started to form and white hairs are prevalent. My plants are no longer increasing in height.

I noticed that a few of the fan leaves are showing the signs of nutrient burn. Should I remove these leaves?

I am using hydroponics. Should I reduce my nutrient concentration at this stage of flowering, or do I have to suck it up at this point? If I can reduce the concentration, by how much should I reduce it? I was thinking a 25% reduction.

Thanks!

What EC are you feeding at now? What grow media are you using? How often do you feed?

Personally I don't take those leaves off until they're pretty dried up. The type of nutes you're using would be nice to know as well.

I am using hydroponics. I am using a concentration of 12 ml Grow, 12 ml Micro, and 12 ml Bloom per gallon of water. The Grow, Micro, and Bloom are from the Advanced Nutrients 3-Part pH Perfect Grow Micro Bloom package.

I pump out my reservoir and add a new mixture once per week.

Thanks for your help everyone.

You didn't answer what EC or what type of hydro substrate you are growing in. Trust your EC meter, don't trust the manufacture's recommended doses.

I just have liquid in my reservoir, so no substrate. I aerate the liquid in the reservoir using an air-stone, in the reservoir, connected to an air pump. I do not know what the EC is. I did not know what EC was, or its importance, until I read your post.

I am using the Cash Crop 6.0 - 2 plant LED Hydroponics Grow Box that I purchased from DEALZER (https://dealzer.com/cash-crop.html). I only have two plants. The reservoir is small, about a one gallon capacity. There is no means for circulating the water, which is why I am only using aerated liquid and changing it weekly. I am currently following the instructions provided with box.

This is my first grow. I think I will tough it out and learn from my many mistakes.

Thank you for your help.

So, you are growing DWC style it sounds like. I don't have much experience with that, but yes you need to learn about ec and ph, get both those meters if you don't have them already, and dial it in. In hydro you really can't rely on the instructions of the bottle, sorry to say.

I know my reply is late, but EC is parts per million, so get a ppm meter for like 15 bucks. For each stage of growth the plant is allowed to have a certain amount/range of salts/minerals in the water. Plan water is usual lower than 100ppm. As you add nutrients the EC/ppm rises. For example, check out the ppm ranges in the grey columns just above the micro nutrient columns. This means you can only put so much for each grow stage.Screenshot_20211103-023823~2_023932.pngEC_PPM_Conversion_chart-526x1024.jpg
