Bottom leafs seem to be dying - Copy&Pasted + picture

[Rusty Trichome]

Going to need you to copy-n-paste a picture of the whole plant, but I went through your form and noticed a few things...

Hey Community!

Hey.

1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's)
2) Distance from tops? 3-5ft.
3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...)
.6) What are the bulb wattages, kelvin ratings, and schedule? 24-hour, 400W

Your lights are too high. Or is that the distance from the bulb to the lower leaves? I go with 18/6 in veg.

Your medium:[/B]
.7) Specific brand and type of soil Mixture of several soils, with rocks at the bottom.

Mediums are not all the same. What kind of soil(s) are you using? Regardless, it's a bad idea to mix mediums. Same goes with nutrients. Pick a brand and stick with it if possible. Some are buffered differently, some are heavy on organics or nutrients, some aren't...

Your nutrients and water:[/B]
10) Source of water? Tap water, boiled pH = 7.5, after nutrients ~7
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)

Why do you have to boil the water?
ph is a tad too high. It would be better to adjust to 7.0, then add nutrients. More on that in a second...

13) Specific brand and N-P-K ratio for each bottle. 15-30-15, everyday directions say 1/4 of a teaspoon, I'm doing 1/8 at the moment to get plants used to the nutrients.
14) How often are you watering between feedings, and how much per watering? I water them everyday with 1/8 of a teaspoon nutrients

I've never heard of a nutrient with a daily application rate. Or are you just using your nutrients to adjust your ph daily, and the application rate is 1 tsp per week? Kinda sounds unlikely though...the 15-30-15 N-P-K ratio sounds more like an every two week application nutrient. All right, I'll bite. What are you using, and why are you using a flowering nutrient during growth stage??

Although it's common, the disclaimer at the bottom of your post won't do anything except show paranoia. If "they" are after you, "they" are laughing right now. But if it makes you feel better, I'm not laughing. < lol >

Anyway...the leaf you copy-n-pasted looks like it's the victim of water damage. When watering, I often have to wend my way through branches and leaves, and if I leave the nutrient solution on the leaves, that's what happens. Plus, the washed-out look is likely from a lack of (useful) light, plus, the plant is scavenging nutrients for delivery to the rest of the plant.

Your plant would perform better with the proper tools for the job. (Consistent medium, proper nutrients, ph adjusting solution...)

The picture of the whole plant would be helpful. Old leaves are old news.

I've been growing my first batch and on my biggest plant, the bottom leafs are starting to die. It's not the absolute lowest 2 leafs, but the ones right above it who have 3 spears. I've read that bottom leafs dying is rather normal as the plant grows. I don't think its nutrient deficiency or over fertilizing since the tips of the leafs are not yellow, and its ONLY those two leafs that are showing signs of yellowness. Check attached photo.
