Hi Everybody,

This is my 1st hydroponic indoor grow. I currently have 6 plants (3 White Widows and 3 AK47). Purchased the seeds on the internet from overseas. This week I started to notice rusty/metallic/copper colored spots with yellowing of the leaves. These are located on the fan leaves. Please click on the pics to get an enlarge view of them. I've read a few different threads, but I'm not really sure what to do at this point. Any feedback would be appreciated. Thanks for reading!

Hi Mr. Shake,

I'm using the Botanicare Pro Blend Pro Grow 3-2-4. Even though the plants are 4.5 weeks old and approximately 10 inches tall, i'm only using enough dosage for a seedling. I'll probably increase the dosage to the mid-size vegetative next week. Thanks!

sorry, server error.

try adding Cal-Mag+ to your water, looks like some calcium deficiency, maybe magnesium, too ... try 10ml/gallon at first, may be able to cut to 5ml, after a week, or two ... get a magnifying glass, and keep an eye on undersides of leaves, check for critters, too, while you're at it ... good growing

Mr. Shake, I'm actually using the Botanicare Pro Blend Grow 3-2-4.

Image Reaper, thank you for the feedback. I'll attempt the Cal-Mag+ this weekend. Hopefully, this will be the end of that.

I'll post pics in a week or so for an update. Sometimes, I wish we had health insurance for our plants!!!

do you have hard water?

yes, where I live (southern california) has pretty hard water. I use the pH down to get it between 5.0 to 6.0.

Here are some recent photos of my plants at 5.5 weeks into veg. They're currently in their 1st week of flowering. I think after the calmag, soaking the hydroton and sanitizing the reservoir and hydroponic system, the plants seem to be getting better. Thanks for everybody's feedback!
