Tub #1 has the larger roots
tub#2 has the smaller roots

I took the ones (tub#2) with smaller roots and switched to my tap water which I will be using from now on. after two days of the tap water sitting out the ppms were at 100. I put 80ppms of grow and 30 ppms of cal-mag. I will go no further then 30 ppms of cal-mag for the rest of the veg just to be safe and see if its okay with the tap water. I will be switching the big one (tub#1)
in 3 days to tap water. I will also be nixing the ppms of the tap water. so I will always be subtracting 100 ppms from the total of the ppm meter.

tub #1 .........160 ppm 100 grow 60 cal-mag
Tub#2..........110 ppm 80 grow 30 cal-mag

both tubs have a few mls per gallon of liquid karma and 10 ml/gal of hydroguard

So I don't think they like all fert in there just yet. My ppms went up over the night and I noticed some fert burn on the lower leaves. I dumped out both or the res. in place for dechlorinated tap water which is set for 5.8 p.h. I will check them to see if the ppms rise in the container from the leeched roots.

They're getting there....lots of this is trial and error as you are discovering. Your plants are doing pretty well for a first grow.....no worries just keep trying and watching the plants for their reaction. Catching a reaction early is your best weapon in hydro.

Thanks for the boost Weedhound. So the fresh water has been there for a day. should I put fresh water in and remove the salts that were leeched or leave the water in for a few more days? They only have at the most 3 sets of "true" leaves. I do have fresh dechlorinated water. i have to get more ph down at my local store so I will post pics when I get back.

Made a few improvements. Light hood made of Duct tape, cardboard, and mylar. Works like a champ.

Tub 1 is at 20 ppms
tub 2 is at 10 ppms

plants are loving the leeching. the stalks are greener already. No more burn detected at all.

Tight internodes. Good. You're on your way. Check for any signs of scorch on the hood periodically. A safer material would be aluminum roof flashing bent to shape and spray painted flat white on the side meant to be reflective. Just a thought since you are in a closet and fire is a definite concern.

Jefferson let me clarify something here. If your ppm goes down then while it IS an indication that your plants are eating it is NOT what you want to go by as far as ppms go.

The norm is more for the number to rise after a few days but either way you don't really know exactly WHAT the plant is eating so frequent rez changes and additions are still very important. What I'm saying is that your ppms going down is not necessarily a good thing. It's more of an indication of deficienies in your solution than plant health.

[JeffersonBud]

It went down when all the plants were in 1 prop. Since I have 2 I decided to split them up to give the roots more room. I think the ones in the larger tub got a little burned because I took 7 plants from that container. Not enough plants to feed at that level.

Thanks for the posts guys. The vent stays cool so no fire will spring up. You can't see it but there is a fixture inside the hood and it is lined with aluminum then the mylar on top of that. Thanks for the advice gents

Cheers

I will also be moving in a few weeks so I will build a proper closet

I see what your saying about the ppms. the light is not very hot so I knew the leaves were not heat damaged. The lower ones were effected first with drooping and curling happening as well. The stalks looked a bit more white and red and not green. The burns started to move up the leaves slowly. the leaves were coming out twisted and mutated as well. Thats why I leeched. After 24 hours the stalks are greener, and most of the red has gone away. The new leaves are looking healthy as well with no mutation or missing blades. I started my ferts as well when there were only 1 set of true leaves with 5 points. I have read that most wait tell 3 or 5 to start.
Simply put I think they look better today then yesterday. What would you guys suggest? tub 1 is now at 10 ppm down from 20 and tub 2 is still at 10 ppm. all are set to 5.8 ph
