Leaf burn and discoloration!

[headshake]

I personally will only drink filtered water, or from reverse ozmosis.

RO is filtered water.

If you go to my grow log...I answer all of the questions from the form entirely. Not to mention, I believe I answered all of the basic troubleshooting questions. The form is retarded...especially since I posted pictures.

first off, it's not peoples job (nor do they have the time) to go from grow log to grow log to read specifics. nor do your plants have the time, for that matter. especially in hydro....but i bet you already knew this.

why exactly is the form retarted? please elaborate? what could be done to make the form better?

the form is in place so the people HELPING save your plants can give you the best, accurate information, as quickly as possible.

it also might not be so hard to fill out if you READ the questions and answered the question asked.

A) Type and wattage of lights. T5 four bulb...2 hot and 2 cool bulbs.

this is asking for bulb type and wattage, yet you posted what kind and well, that's about it, i guess you were trying to elude to your kelvin ratings, which the next question asks for.

D) What are the bulb wattages, kelvin ratings, and schedule? 18/6 light cycle...wattage is about 350 watts

here is where your kelvin rating goes. yes it asks for wattage again. like i said, it's a work in progress.

E) Is there a consistent fresh air supply? yes...two oscilating fans...an exhaust fans

this is a close ended question. that's either yes or no. no room for elaboration here.

F) Do you have an exhaust fan and a circulation fan? yes...already answered this redundant question

not redundant, it's an open ended, follow up question. what size exhaust fan are you working with? (CFM) what size is your grow area?

just because you have an exhaust and two circulation fans doesn't mean that you have good circulation. you could be just swirling hot air around inside your area.

also keep in mind that the new form is a work in progress!

as far as the pics go, you can't just plop a pic in front of someone and say "diagnose my problem". it doens't quite work that way. i mean if it did, you'd have fixed your own problem without having to post.

once agian, any feedback to the form will be greatly appreciated. and "it's retarded" is not feedback.

thanks.

what size t5s 4 4ft t5s is only 200w

circulated air is not fresh air as the question is not redundant

how do you mesure ph cause i believe distilled water is nuetral, what brand

if you want help man u gotta keep it real.

hello martyrprojket,

First thing that strikes me is PH, for rockwool the target to hit is usually 5.5. I personally find 5.2 to 5.5 works best with my nutes and RW setup. (BTW in the form you say 5.8, but earlier said 5.5, which is it?) Find out what the manufacturer of your nutrients recommends and start there.

Second if using distilled (or RO) water in hydro, you need to add a little cal/mag, this allows the nutrients to be available to the plant.

Third was just touched on, amount of light seems limited. In the form you say "abt 350w" but a T5 in 4' (you don't mention size) would be 28w/ea NO (normal output) or 54w/ea if HO (high output) and 85w/ea if overdriven to VHO (very high output). So 4 t5s would be 112w, 216w, or 340w. Are you using an electronic ballast to overdrive? If you are then keeping the lights 2-3" is way too close, you need 5-6".

Fourth thing is whether you are feeding or not. But when you do you need to go easier then recommended by your nutrient mfg. Without the benefit of a PPM or TDC meter you'll be running blind, so keep in mind "less is more".

We all know filling out the troubleshooting form seems like a bit of work and a pain, but it puts as much info available, together in one place. Makes it easier on us to try to help you, rather then the other way around.

Good luck, let us know how things work out.

Just took a second look at your pictures and it just dawned on me....if those are 4" delta blocks, and they are 4 rows of 4, you have an area of about 2'x2'. Maybe the form should ask, "what size is the actual grow area?" rather then size of grow room.

It wouldn't hurt to mention size of T5s as in 2' or 4', wattage and degrees Kelvin.
