I see the drip stake right at the plant. How wet are the rapid rooter plugs and rockwool. Maybe that. Might want to direct the drip away from the plant a bit. rockwool can be tricky when watering but didn't you say only one water time a day. HMMMM. They don't look that bad but it does look like nute burn somewhat.
So I found the issue...those plants were not rooting properly. Rooting out of the rapid rotter was non-existent. 8 plants are doing fine, their roots made it through to the bottom and they are already outside of the rockwohl.:thumbsup:
I am wondering now that the roots have gon through the bottm of the rockwohl, if I should put them in a hydrotron medium?
I removed the plastic wrapping from around the rockwohl, I was starting to believe I was over-watering. I even thought that perhaps the plastic wrapping was not getting enough oxygen to the roots. But, the cube was light and it was bone dry in the middle. Water was the issue, just a lack of it. I put the plants on 2 watering cycles per day.
Nutes and Ph are perfect. I had to toss the plants that were not doing hot into the humdity dome, and put them under 3x120 watt CFL bulbs in my clone room. I want them to root better before they go into the rockwohl. I am sure most of you will agree with this decision.
I have my strongest 8 little girls under my t5 light in the main veg room. They all have extensive rooting outside of the rockwohl cubes. I am very happy with them so far and I am positive they are going to be sexy little bitches!
I have also decided to buy some clones to work out any issues I might have with my flowering setup before the little girls get into the stage that I can take cuttings from them. I think this is a wise move to make sure I do not have any issues with the setup prior to heavy use.
Also, my white widow showed up. Started their germination last night.

I have a very similar setup to yours. I'm currently growing six plants in a 4 inch rockwool cube buried in hydroton. They've been vegging for 6 weeks under a 8 t5 bulbs. I would definitely recommend more t5 bulbs if ur space allows it. :thumbsup::smokin::pimp:
glad to hear you got it figured out Marty!! :thumbsup:
I want to first start by saying thank you. I had three different issues going on with my grow. Lack of light, lack of water, and the nutrient solution needed to be adjusted.
Adjustments made:
Besides putting the smaller plants back into humidity dome under another set of CFL lights. I began to notice weak root structure in these plants based upon where they were places in my 2x2 tray. I was not feeding them enough water with nutes, and I was also lacking light to a number of the plants.
Major issues solved:
Lack of light (lumens)
Lack of Water
Lack of nutrients
This tri-fecta of problems with kill 80% of your plants. Even the luckiest of growers will be able to keep 2 out of 10 plants.
Plant Status:
You can already see the difference in one day. Of the strongest plants that were showing signs of spotting and minor wilting, are now perfect little girls again. I love the resiliency of this strain...I definitely recommend this strain to first time growers. Just be prepared to have to prop up your seedlings as they are prone to being leggy.
The new growth is strong on all of the plants under the T5 light. Root growth is through the bottom of the rockwohl, and I will be adding hydrotron on Monday. I need to give these roots more oxygen and this is the best way.
Enjoy the pictures I am supplying for you. I think you will all agree that this system is definitely working best so far.

I am on this already. I just ordered another T5 light with 8 bulbs....should cover this entire veg space with light. 4 cool and 4 warm bulbs. Remember that this is my second veg area. I will only be using this 2x2 tray for mothers. The strongest plants will the the founders of this room. The other females will be flowered...just for the fun of it!Quote:

From what I'm seeing you still have your seedling leaves, you should wait until those fall until nutrients are added. The marijuana plant has nutrients stored in those seedling leaves to get it going in the world, once those are gone it then relies on the root system that has established over its seedling phase. So my suggestion would be back off on the nutrients for now and make sure that temperatures are hospitable for your ladies. Good luck bro, happy growin :rastasmoke:
According to every website that sells nutrients...You are supposed to add nutrients to seedlings when growing via hydroponics. Advanced nutrients and General Hydroponics both recommend using nutes with seedlings.
CLICK HERE FOR THE GENERAL HYDROPONICS LINK FOR NUTE SCHEDULE...
I don't want to be argumentative...but, I honestly do not think they would say to use nutes if they didn't think it was a good idea. its not like it is enough to make you have to go out to buy more...1.5ml for each gallon is not a big deal!
The funny thing is that with growing...there is always something new to learn and add to your growing system. You can always be expanding and learning more, otherwise we would all still be smoking dirty hippy schwag! Feel me there?

as I suggested earlier a WEAK mixture for seedlings/clones is acceptabe. If you run 100% nute mixture you will kill them real quick but using 1/8 - 1/4 str is fine. As Marty stated even manufactures give you this info right on the bottle. A drop of ST per gal also will help with root development and growth as this is a vitamin supplement that allows better intake of nutes and such.
Key word "sells". I try to ignore the doses and growing info from the bottles, the simple facts are that ofcourse the manufacturer to the nutrient solution is going to recommend that you use their product as much as possible (means more green for them) and those directions that you read are not specifically for marijuana.Quote:

I'm not trying to be argumentative but those recommended doses and schedules were not created for the marijuana plant. Live, learn and toke :rastasmoke:
