I will attempt to make this as brief as possible.
First grow ever.
Hydro.
Raw water is PPM 375
Installed small RO system
Using Masterblend 3 part dry nutes
Started hemp seeds as guinea pigs
(In Aeroponic bucket (like used for cloning) using Rapid Rooters in 2" net pots)
Didn't realize that Cal-Mag was needed with RO.
Started 2 legit seeds, Kush and Cookies CDB form Seedman's, same method.
Developed Cal and Mag def's.
Ordered Cal-Mag
Major stunt of growth in both hemp plants and seedlings.
In the mean time, mixed raw and Ro 50/50 as base water and seemed to help.
Cal-Mag arrived, realized I was under feeding and slowly up'd PPM from 150ish to 400ish.
Plants improved.
Seedlings rooted well and are transferred to final home, 5 gal totes with 2 gal fabric pots filled with hydroton in a E & F system.
2 separate totes draining into 1 - 17 gallon res holding 10-12 gallons.
Environment is:
5'X5' grow tent
500 watt (from the wall) DIY LED grow light, 300 watts of 5000K lights salvaged from street lights and 200 watts of 3000k EB gen2 strip lights
Light is being ran at 50%. Light is 2'x4' centered over the two totes.
Heater in place to maintain temps of approx. 75 F.
Humidifier in place, having difficulty raising RH above 50%
Input fan with variable speed to maintain air exchange
Single res is outside the tent. PPM is 540, PH ranges from 5.4 to 6.5
Timing on E&F is currently 10 min ON/ 3:50 OFF, changed from 2 min ON/ 58 min OFF
Current situation:
Seedings are yellowing (from bottom up)
Hemp plants look great. (Separate Res)



To me this points to an issue related to the new large res.
The large res contains the Masterblend 3 part (Mixed; 2 parts MB, 1 part Epson salts, and mixed in last 2 parts CaNi), also 4 ml per gal of Cal-Mag (started at 2/gal and then 3/gal and just today raised to 4/gal.), also Southern AG beneficial bacteria (like hydroguard)
That's where we stand....
Is this just transplant shock, and I'm a nervous NOOB?
Is this N def, yellowing from the bottom?
Is this cal-mag that was to low with RO, like I was having before?
Is this one of a hundred different things that I currently don't know a damn thing about?
I have loads of details, but this post is already a book...
I tried to give the info that I thought was most relevant.
Input on my situation is requested and welcomed.
Thanks in advance,
WillieP
