advice please

Lets get to the details for veg
3 100w CFL's running 6500k
1 small 6inch fan
DWC system with 15 sites
Milwaukee 3-1 ph/ec/tds meter
2 and 1/2 gal of RO water
2 6'inch airstones
Rockwool cubes
net baskett

Strain
Northern Lights x AK47
Sugarberry (Widow x blueberry)
put into cubes 19 days ago
running 5.8 ph
140 TDS
Botanicare products
Pro Grow
Liquid Karma
Hydroguard
18/6 light cycle
temp is 72 degrees f
water temp is 70 degrees f

Things are looking ok so far. Good root growth in about half. White roots except where liquid karma attached. Some of the stems have turned red though. I just changed the nutes and water today. Before it was 110 tds and looking good. I want to introduce some cal-mag soon. Some of the new leaves are twisted and a bit warped. Leaves look a bit pale green but they are still young. Should i introduce more nutes or is 140 enough? are the red stems a nute deficiency because I dont think its a trait of any of the strains. What do you guys think?

Hope these pictures work

By all means....start your CalMag asap. I start CalMag the first time I introduce nutes to my seedlings. You could raise their general number as well....but props for not pouring every thing you can get your hands on into your res and frying them. That's generally the biggest mistake folks make. :thumbsup:

Good luck.....sounds like you've really put some work into it.

PS....when your ppm drops like that (140-110) they're hungry!

[JeffersonBud]

Thanks a lot. I have tried this before but I did not have a PH or TDS meter. Big rookie mistake. I will introduce the calmag today. I am going to start using tap water as well because it is only about 140 TDS here.

[Weedhound]

Ok well you should pick one and stick with it......if you use RO water....you need Cal Mag. If you use tap water.....you shouldn't need Cal Mag.

Right now they look like they need some good minerals etc so decide which way you want to go and go for it!

[JeffersonBud]

I introduced cal-mag a few minutes ago. 35ppm for now and I will slowly go up as needed. I was reading the sticky for Botanicare products and was under the impression that for cal-mag the grower was using equal doses of grow to cal-mag with RO water. That was just his experience so we will see.

The water temp maxes out at 72 and drops to 68.
The PH is holding steady at 5.8. this meter is great! I have always calibrated it every week but it never needs it. It is only off by 15 ppms after 3 weeks of use but calibration fixes that.
Its weird how the ph of RO water is so low. 3.9 i measured. guess thats due to some carbon gas in the water.

PPM's with pro grow and cal-mag are at a total of 180. I bet they love those trace elements.

[Weedhound]

Sounds good.....I'd stick with the RO water and CalMag if those are working for you. Tap water is fine as long as your ph stays stable with it and it has enough calcium, minerals, etc....for your plants. Again....just not both together.

Good luck.

Thanks for the help Weedhound.

Oooooo thats' LOVELY looking. Buckle up your seat belt though when you take your ride with that stuff.

[JeffersonBud]

got a recipe up of what I made in that section of the forum. I let the butter simmer for 21 hours on low. Got up and stirred it all night. will post results when I am able to function.

Funny I just saw who posted the Botanicare line above. haha. thanks weedhound.
