hey bro its looks like the water temps a lil to cold for ur babies?? not sure but a lil light yellowing on new growth will cause that....its cant stud ur plants too..not sure cant really tell ..keep it up loving updates every other day.....

hey blue, I think the yellowness in the leaves are from me dropping the PH every day last week down to 5.3. Again my first time running hydro and made the mistake thinking that needs to go down to 5.3 and up every day.

Stu you dont have to do that. After I mix my nutes if the ph is in range of 5.3 - 6.2 I leave it alone. I try not to add any ph up or down if I can help it.

I know I haven't done it since you told me last week. I was explaining to bluewaves why I think I'm getting yellow like color in the leaves. I don't think its from keeping the rez 66-70 degrees. That should be prime.

Got some big Movin Cools in at work today. Damn do I wish I had a set up big enough to use these bad boys.

Plants are looking great. I finally got the humidity dialed in and the leaves are starting to POP up on the plants.

Hey hiboy, the stuff is call Reflextix. It can be bought at Home depot that is where I grabbed mine from. Here's a link. Reflextix.

Nice and clean setup stu! Your photos are great and the plants look like they're about to take off... Also I looked back, but didn't see how much CalMag these girls are getting... Seems like they could use a tad bit though...:cool

Ya base nutes I'm using Heavy 16 they are saying that they do not need a CalMag additive. But clearly it needs it. Look like I will take a trip to the shop tm and grab a bottle. Thx for pointing it out Shady.

Yeah I haven't used their nutes, but I'm very interested in them... Also Dutch Masters says not to use any CalMag either, but I needed to add a small amount cuz I was running below their recommended dose from their nutrient calculator... :thinking

interesting. ure havin a calmag def while using heavy16?
i just started my first run with them and was also told no need for magical etc. i only thru in cannazym, roots excel, and a foliar right now while in veg.

great setup and genetics.
keep me posted

How much cal mag did you add to you formula, ml/gallon?

Hey boomer thanks for stopping in. How do yours look in veg atm ? Also what ml/Gallon are you using for the Heavy 16 for veg? I might have under dosed them.

hey stu have u lift up the reflictive stuff up to see if u see any damping around that top part ur covering???

Bluewaves hey man. Ya it is as dry as can be. It is not holding any moisture underneath it at all. Plus the chiller isn't running that much either.

thanks for all the input guys

I didn't add any when I first filled my system, but began to add 2 ml/gal of CalMag to RO during manual top offs. Also I added 2 ml/gal of CalMag when I mixed the bloom nutes and flipped, but I couldn't completely drain the veg nutes... I'll provide more details on my next update... :cool

Thanks for the info Shady. Like I was telling BudLust I think I didn't add enough veg base nutes to the mix. I was just going off of the PPM. Will be watching for your next update.

i started off with a light dose (5ml/gal i think...) then let the mixing rez settle for 2 days and took PH/PPM readings and was around 350-400ppm. I wanted to start higher then that for veg since i prevegged a little in my ezcloner with GH macro @ around 400-500ppm.
So i added i think like 3ml/gal more HEavy to balance the ratio out and increase ppms but it went higher then i wanted. i think like 800-900ppm. so i played the balancing game of RO here.... PH down there... etc. its not how i want the rez mixing to go but with any new system u gotta learn the shit and make tweaks as u go along.
anyways regarding the calmag im thinking about adding a small amount in myself since during transplant i had noticed interesting deficiences that im not sure wat exactly it all was. mite of been hardwater issues before when i started rooting. my tap water is terrible at the shop. sumthing like 500ppm at 8.0ph so im always using RO now. now that the older leaves have been sucked dry from nute uptake, its leaving strange signs on fan leaves. End result my ladies are working to get bak to a dark green during veg as they should be. ill be doing an update in a couple days and get bak to u once i see how the adjustments worked out.
i know the owner of Field16 ag so im gonna give him a ring and see whats up cuz even he said no need for cal mag supp.

Since I was going based off of PPM I calculated I only used 3ml/gal. I think I under dosed them. Went by the shop and grabbed some CalMag just to be safe. Going to do 2ml per gallon later today when lights turn on. Will keep you posted. Let me know what you hear from you buddy over at HVY.

From Heavy

"Calcium deficiency is usually characterized by tip burning then mottling, but calcium deficiency can be brought on by high humidity and a lower evapo-transpiration rate regardless of large amounts in the nutrient solution. The only systems I have ever seen needing any Cal Mag amendments are with raw unwashed fresh coco coir that can have K in the 1000 ppm range. Since you guys are in a pure water culture system, there is no need for cal mag. In the grow room with sufficient lighting, the humidity needs to be adjusted to around 40-50% to get the vascular system bringing up fresh cations of Ca and Mg. Also if the roots are not large enough and the canopy is big, there can be deficiencies in uptake. You want a root to shoot ratio of no less than 1:1 with 2:1 and higher being optimum."

Hope this helps bro

Day 14 Veg

PPM 510
PH 5.9
Water Temp 67
Air temp 81 high 65 low
RH 82%-51%
Co2 490

I dropped the light about 8" lower trying to get these guys to get moving a bit quicker. Ended up adding 1.5 mL of CalMag to the rez. I think I under dosed on the base veg nutes. Will keep and eye on it and see how it looks.

Bud thanks for the info. That high humidity above 70% is from when my lights go off and the temp drops from 79-70. When it does the RH is in the mid 60s. So that 9 degree drop in a few mins knocks up my RH. I do not have he Dehumidifier running at this moment because of the lack of a good Humidity controller. I am still fine tuning trying to get it right around 60%.
