Guide for Diagnosing Plant Problems

I'd go with at least every other day. Daily might be just too much stress at this point, soaking the media up like that. I think you should have plenty of moisture for growing with every other day saturations.

And no problem man. I'm glad to offer what advice I can.
 
I'm a newb growing in soil. I use House and Garden nutes by their recommended doses. Do I ever have to worry about deficiencies other than N? Do all these deficiencies only come up when people are trying to save using cheap ferts that might not cover all nutrients?

There is a lot more to worry about than Nitrogen deficiency. There's all kinds of toxicity issues, and pH issues, that can crop up and ruin your day.

What you're doing is not ideal. You're growing in an organic medium that depends on a delicate balance of pH to maintain healthy microbes which break down larger molecules into food for the root system. By applying a hydroponic, salt based, nutrient you can upset the pH balance and damage or kill off the microbes with the inorganic chelators used to keep the metals and the salts from precipitating in the nutrient solution. Then the whole system starts breaking down.

I'm always perplexed at people who use soil, but then feed it with salts. I mean, just get yourself some coco and then you'd be doing it right.

Most deficiency is a result of pH imbalance or an over abundance of one element preventing the uptake of another. Micro deficiency is common, especially calcium and magnesium, but again... more pH related.

Oh man, I think I screwed up. I sprayed an aerosol insecticide on my 2 week old plants for spider mites. I think I burnt them! The leaves are turning
brown and the newest leaves at the top of the plant are turning yellow... I made sure I held the can 16"-18" away to try to
avoid any damage. They are Barney's LSD and Kannabia Power Skunk. Anyone know if they will survive? Is there anything I can do
to help them?

You might try rinsing them off. With some sprays it's ok to use them but you need to rinse it off after a short time of it can burn them. I did it myself once.
 
Ok, will try. It was pyrethrin spray so I thought it was safe. I think the propellants in spray's like that
are alcohol or something. Thanks for the advice and good to see you're from the Northeast!

Hey neighbor, ya I'm in Ct. not far from Springfield and have friends in that area. Always nice to see some one close. In a better world we'd be saying "hey got some time, maybe come check out my grow and do some sampling". Without looking it up more I think you are right in thinking it should be safe. To be on the safe side I would always try to rinse. When I did it once I used "Liquid Sevin", and I knew I should rinse but just forgot until it was to late. Really fried it. That was some nasty stuff but works great. I will not use it at all again. But it sure Killed them. But what is safe for a little older plant might effect a seedling different. You could use another type of plant that they might like better and would be attracted to first. I had a dark purple Coleus plant in the area once that had mites. They were really easy to see. I sprayed it with something (don't remember what it was) but it was not Sevin. It killed them and I never found any on my plants and that was a couple years ago. No problem since.
 
I would have loved to check it out but the world just hasn't progressed that far but maybe some day. Keep growing
'cause someday we will change the world!!
 
Hey guys, starting my second grow. My first grow was in coco soil with BC Nutrients. Turned out to be a pain. BC nutrients have to much K, which reacts with coco soil and blocks nitrogen from getting to plants.
On my second grow I will try eb and flow system with a rock-wool media. After my first grow I am still confused what nutrient to use. Schedule of feeding of nutrients is pretty important too. so I was wondering if you guys can post which nutrients worked best for you, and your schedule of feeding, for example when I should start feeding nuts. and at what dosage. Please be as detailed as possible.
Appreciate any help
