Aurora Indica/Silver Pearl DWC Bubble Buckets

I Started this grow November 27 when i germinated 5 AI seeds and two days later 4 of 5 were ready to get planted but I was still waiting for some stuff so they were planted into there pots on the 30th. They ended up sending 3x3 rockwool cubes so i cut up a spare and made them work. I let them soak and planted the seeds and let them grow. Fast forward a week and a half...they're all different sizes. One is small and kinda shriveled up, it has darker green leaves the other 3 look good but are growing at different rates. The smallest healthy one has two little yellow tips. probably nute burn so tomarrow I'm going to flush it. I was also thinking of germinating two more to replace the little dying one. My setup is a Individual 4 pot DWC with 2 air pumps feeding 2 buckets each. My light is from HTGSupply and it is a 400W MH/HPS setup. It is about 20" high. My daytime temps are 85-78F with nighttime temps at 65-67F. Humidity has ben an issue my sensor located by the top of the plants is reading Lo <20%. I had a humidifier in there with no improvement. I went and bought another today and had to running all day with no improvement. I can feel it in there but it doesn't read. The new humidifier is set at 55% and i here is turn on and off so maybe under the light there is low humidity or i need a new guage. I plan on making a res. here soon to have more water circulating. The Nutes are General Hydro Flora series. Pictues later tonight as soon as i find my camera.

Well i figured out my humidity issue. I had my monitor mounted outside the door with the temp sensor inside and then the humidity sensor was on the base and was actually reading the humidity in my room not the closet. So there is good humidity now. Now I'm hoping my old one is good enough and i can return the new one and build a nice res. I also started to germ 2 Silver Pearl seeds today in case the one doesn't perk up. The RO water machine was broke at the coop when i went today. I'll have to try tomorrow.

Day 12:

The 2 healthy plants (#2,#3) are doing well they are green and growing. There doesn't seen to be much growth on the other 2 (#1,#4). #1 was the best growing in the first week and then just fell off. It has small shriveled leaves and slow growth. #4 is growing slow, slightly darker green and has a little nute burn on the second set off leaves. I dont really think it needs to be flush. It happened a day before i changed the res water, I think there it was just bad ph. It has the same nutes as the rest and there is nothing on the new growth but is still slow. I'm tracking down a camera so you can see what I'm talking about.

Temp: 87F
Humidity: 40%
400W MH 22"

Day 13:
I pulled the AI #1,#4 last night and put the 2 extra air stones in the other buckets in AI#2 and #3. Im going to plant the 2 Silver Pearl seeds today they germed in 24 hours and have approx. 1/4 taproots. I have 3x3 rockwool blocks soaking in ph 5.5 water i'm going to rinse those soon and get those to setup in there buckets. They will be 2 weeks behind the AI, but i don't see a problem until the AI wants to flower. The Co-ops RO machine is broken so I had to switch to Distilled until it is fixed. SP #1 #2 will be starting with 1/4 GH Flora Nutes with the water level an inch above the net pots.

Day 14:

All is well today. SP1 is already peaking its first 2 leaves out. The Underside looks like brown/purple..tops are green!? No sign of SP2. AI3 is the bigger one and AI2 is the slightly smaller of the two. Both are growing nicely with a ph of approx. 5.8.

Here are the pictures:

lookin good so far...

Thanks its pretty much just a waiting game now my setup is working decent. I'm hoping the Silver Pearl grows quick and catches up. I think I'm going veg the AI until the SP is ready and hopefully get some clones from the AI. They are 2wks apart. Whens the best time to clone?

SP1 now has its first two real leaves, but no sign of SP2. Im not going to be able to tend to these plants as much in the coming weeks due to working out of the area. I'm hoping that they will be able to go 2-3 days at a time on there own. I'm going to be making a recirculating res to keep the system more balanced and hopefully stable for 2-3 while I'm away. Any Suggestion are welcome!

2-3 days isnt so bad, just make sure you do something to counter the pH raising up....
Ive seen some people say they Re going away from there plants for 2-3 weeks for the holidays--I would worry like crazy if I had to do that!

Does anyone trim there indica? mine has SO many leaves. SP1 was starting so stretch so i raised it up a little closer, And SP2 finally showed up. I cant believe that the AI is only 2 wks older, they grew fast.
