Indoor Northern Lights Auto x 5 do they look ok??

[growdiesel]

hey guys,

just looking for some feed back on how these guys are looking. i see the edges of some of the leaves curling up... here are the stats for them..

planted after paper towel 10/27/14

roots organic soil in 3 gallon bags
(1) 400watt HPS
(1) 150 watt CFL side lighting
(1) 300watt cfl side lighting
2'x3'x5.6' tent
(1) 4" HV inline fan ductiong
(1) 4" HV inline fan intake
(2) fans inside tent blowing

temps 74-83 degrees
humidity 38-48%
used nutes two times onyl so far at 1/3 dose recommended (buddha grow)
PH of fresh clean water is 6.8
PH of Nute water is 3.8-4.0 (only use about 1 or 2 cups of nutes at a time the rest is clean water.

400 watt HPS is 16-18 inches away. up until tuesday the HPS was only 6-8 inches away thats y i thought i had curling originally. but moved it up and seem to be the same but they are growing faster.

leme know how you think they are doing. today will be DAY 10. sorry if i posted pics wrong. \

thanks guys

Strikes me that 400 watt hid 6-8 inches over seedlings is pretty close and that hps bulb is not your first choice spectrum for seedlings but they look fine. Is that how you've started your plants in the past?

I'm trying to learn from you. What does this mean:

PH of Nute water is 3.8-4.0 (only use about 1 or 2 cups of nutes at a time the rest is clean water.

Your runoff measures 3.8-4.0? You mix nutes into 1-2 cups of water, ph 3.9, pour it into your containers and follow with plain water?

this is my first actual grow. tried a few years back and got 6-8 weeks in an killed the plants with nutes and a fly issue.

what i mean by PH of nute water is... i mix my 1tblspoon of buddha grow with a gallon of water. instead of 2-3 like it states.
then i test the gallon jug after i let it sit for 24 hours and the water PH with nutes is 3.8-4.0.

my run off is measuring at a 5.8-6.2. mostly around a 6.0PH after using nutes and testing the run off.

so i am to believe my soil it at about a 6.0 PH level.

after i lightly nute the plants i use distilled water and kinda flush the nutes through a little bit. i dont know much and maybe im over analizing but i do that to just kinda flush the nute water away from the plant a little bit so it mixes through the soil around it. (probably not needed)

thanks for showing interest and a reply.

In my opinion, and a few other senior growers on this site may think you are adding nutrients about 5 days too early.

Raising the light was a good idea, and if leaf damage occurred, they may stay curled permenantly.

Not to worry, see if the new leaves are curling or not, you may have fixed that part.

Vegging under HPS is a little much, but if it was you have then use it. BUt you mentioned the CFL's, which could be a better alternative until you progress into flower.

Just suggestions on my part, not the "golden" word by any means.

If those numbers on your PH values are correct, you may need to adjust your water.

This is from GoAuto

[h=2]Rough Calculation Guide:[/h]

Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference

If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.

For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5

If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5​

And it can be found in the thread below, which you should probably read, it will teach ya stuff.

Eekman - thanks allot. i will keep an eye on it and i will look into taking away the 400w HPS and leaving only the 300watt cfl and 150 watt cfl. i do believe the lights being so low is what caused the curling in the first place so i had moved them up and they didnt curl any further and the one that was the worst looks even greener now.

when is a normal time to introduce the HPS?

thanks

You're plants are one week old?

They only need the cfl light for now. The bulbs should be 6500k.

Your feeding routine is unusual. First off, they don't need outside food agents yet. Second if you are feeding with 4.0 ph solution that is way too low. It should be adjusted to 6.5 and then fed from that container till runoff. You don't have to let it sit for 24 hours nor alternate nutes and plain water in the same feeding. When you resume feeding after a couple of weeks make sure you follow the feeding schedule carefully. You say you're adding 1 tablespoon per gallon. Do you mean teaspoon? The feed chart says:

[TD="bgcolor: #000000, align: left"]Budha Grow
[/TD]
[TD="align: center"]5 ML[/TD]
[TD="align: center"]5 ML[/TD]
[TD="align: center"]10 ML[/TD]
[TD="align: center"]15 ML[/TD]
[TD="align: center"]15 ML



[/TD]

Week one says 5 ml. That's one teaspoon. Week one. Your plant needs zero ml week one. By week 3 it's 3 teaspoons=1 tablespoon. Either way you're over feeding.

As for using routine ph runoff formula for any purpose, if you're pouring a cup of 3.8 nuted water followed by a rinsing of 6.8 fresh water there's no way you can make heads or tails of the result.

Be careful.

yea i meant teaspoon and now i understand thats still too much. glad i didnt kill them yet. obviously i am new to this and learning so i appreciate the advice.

ill run out and grab some 6500 bulbs today and swap those out. when should i introduce the HPS again?
will the plants have negative effects from taking away the 400w HPS after being on them for 10 days?


so i guess my curling is from the lights originally being too low, and then too much nutes. they didnt yellow much if any luckily. i always feel like i am being real meticulous about everything when come to find out, i wasnt even doing it properly. did tons of research but you guys are helping much more.


thanks

Get yourself a 400 Watt MH for vegging. They cost about 20 bucks. Yea I would raise it up, let the plants adjust and bring the light down inch by inch until you see how the height effects the growth. I was told that when I started. I started with a MH for vegging and switched to the HPS for flowering. You probably would save money because you already have a 400 watt system by just buying a MH instead of a bunch if CFL's. Make sure you have a fan going 24/7. I have a 5x5 small cubby in my attic for my grow room. I have 4 autos and 3 photo's going. This is my first grow and I am doing good. autoflower.net/forums/f35/hi-all-my-first-af-grow-37161.html#post701017

HPS is used mostly for flowering and a Metal Halite is used for vegging. The MH/HPS combo has been the professionals choices for years! Remember these lights have been out years before the CFL or the LED and have proving themselves for years with beautiful results and yields!

has anyone figured out why HPS flowers so well? I have never used them because of heat issues. I grow with fluorescent and have recently begun playing with leds but the SPD for hps lamps does not match the action curve for plants.so why does it flower so well? understanding this would help design better led lights but could not find any studies or information on the net to answer this question
