I'm wondering when I should be bumping the feed to 600 ppm. This is what one of the Dr. Funkenstien's top looks like.
500 to 600ppm is pretty safe for the entire plant life.
mm I have grown in several of heaths designs and theres still a flooded tube set up in one of my old residences that the newer tenants are running.
Its all depending on your environment. In my rooms theres no way that 600ppm can keep up with the plants demands because of light intensity. Check snypes thread post #300.
I would not be afraid to bump up the feed, if they start showing signs of too much food you can take a couple gallons of solution out and replace with plain water or weaker solution. Look for the claw on newer growth that usually means you've got to much food.
I have three Dr. Funkensteins in 5.5" pots getting 600 ppm every four hours. Right next to those are three Sour Urkels. Pictured are the Dr. Funks. They have some sort of issue going on and I have no idea what it is. Only the Dr. Funks are showing this. All other plants are absolutely fine. Any help? What is this, why is it happening and how do I correct it? Thanks, all!
that looks like early broad mite damage. i hope not!
Do a heat treatment by getting your room up to 120* f. You'll need a laser thermometer to verify your temps. Bring your bulbs down low towards the ground and shut off your ac and ventilation. You may need an electric space heater also.
MM have you had broad mites before?
...shouldn't the mites be attacking all my plants?
All of my clones have come from the same source and it (the source) has never been an issue. Again, the only plants seemingly affected are the Dr. Funks. There are three Sour Urkels juxtaposed with these three Dr. Funks and the SUs don't seem to be having any issues whatsoever. I'm confused...shouldn't the mites be attacking all my plants? The two vegging Strawberry Caughs are strong and bushy as ever. I'll buy some glass in the morning and see what I can see. Hopefully there are no creepy crawlies to report. Mum's the word, right?
