Take a picture with the flash, or take them outside the tent, are they still purple? I think it’s your burple light making them look purple.

  • What strain, Seed bank, or bag. it’s a autoflower GSC from ILGM
    Method: Hydroponics
  • Vessels: DWC buckets with a clay medium( have A RDWC that i think I will swap out on monday.( just changed the nutrient solutionlast monday)
  • PH of Water, Solution, runoff (if Applicable)
  • PPM/TDS or EC of nutrient solution if applicable ppm is 365, when I do ec i get 776.
    I used reverse osmosis water and have been changing buckets every sunday or monday with R.O. water.
  • Indoor or Outdoor. Indoors
  • Light system 1500 watt led grow ( will send a picture) will have a really nice one soonish
    *water temps are
  • Humidity; day 79% Night 67%
  • Ventilation system; negative, waiting on the inline fan and carbon filter to get here. I do have a 9 inch fan circulating air the fan also has the co2 feed hose taped to the back so it will disperse co2 evenly. Co2 isnt running yet. The room.this tent is in is small so I am going to make it a lung room meaning it will breathe air from room so that I can effectively use co2 with it
  • AC, Humidifier, De-humidifier, the room is a/c no humidifier. Do have a dehumidifier ( waiting on humidity controller to install it) do I need a humidifier?
  • Co2; Yes, not currently running. ( should It be?)

These are the pics

@repins12 @Zee @Kan72.

IMO, they look fine. New growth, good color at least in the 6th picture down. I am a new grower, and in straight soil. Let the others chime in.

@SKORPION, saw him around earlier. Thoughts?

You really need @RandomlyRan or @peachfuzz to advise on hydro, not my area.


Happy Birthday @Zee :fireworks: :firecracker: :beers: :clinking_glasses: :tumbler_glass:

How high do you have your water level??

@repins12 thank you! Cheers my friend :beers:

its BLURPLE LIGHT bouncing on your leaves

It’s full. Should it be lowered?

Yes it should be lowered! The water level need not bebto the top of the rocks. In my opinion, you placed the seedlings in too early. They should have a tap root coming out of the rockwool or what ever you used to sprout them in. The water level should barely be touching the end of that root. In fact, if the hydroton is moist from absorption the water level can be to the bottom of the hydroton and all you do is drip some water near the plant from the top a few times a day. The root will then reach down for the water. If you have a bubbler… it splashes water a bit. Lower the solution as the root hangs down until it barely touches root, the splashing of the bubbles will be enough. Continue this process until 5/8 of the pail has solution and the rest is air. The upper portion of the root feeds of the air and the submerged portion eats water and nutrients. At all times the root needs that separation to be active and healthy.The roots will grow fast to get to the food, just remember that they need air too. Or else you will suffocate them. No different than overwatering in soil!
In its purest form check out the Kratky method on the internet. Great for lettuce! Somebfolks have tried it for weed and it works to a point… but its the concept of the root system in a liquid that is important.

Aside from what was said. Drop water level to 2inch below net pot. Dont keep water level on net pot ever.
Moisture from bubbles popping gets on the hydroton and that’s all it needs. The roots will grow into the water.
Make sure to treat water with 1ml/gal of each feed that your nutrient recommends for seedlings.

There is no need to set water level to the root. The root grows to the water… chasing the moisture.

Ah I didnt use a rock wool cube as instructions for the autoflower said plant directly into final pot so that’s what I did lol

What they said :point_up: I have had water level touch the bottom of the pots but. only when seed ling goes into net pot and I am using 10" net pots, they are deep and plant/seedling rapid rooter bottom is usually suspended half way up. Then 1 1/2-2" air gap from that point forward. Some people start with the air gap below the net pot and top feed to get roots to seek the solution below and that is the recommended way. The way that I do it just works for me and I haven’t had to top feed. @BamaGrowLabz did the same thing when he set up his hydro. That’s just the way I do it and it is only at initial fill up and then I maintain at least 1 1/2 -2" clearance from that point on. Usually by the time I need to add water roots are outta the bottom of the net pot


Its ok for the solution to touch the basket in the beginning because the hydroton has airspaces. But as the root extends intonthe solution thats when we want to create the separation between basket and solution. The bubbles exploding spits on the roots lije an aeroponic system until such time as the root starts actively feeding… I bet thats what you see! Once the root isbin the solution and the air gap is there thats when the plants kick off and really start to grow!


That’s my understanding as well, my brother. When I looked at his pictures, I could see the water at the top of the hydroton, that’s why I asked what his water level was, to make sure my old eyes weren’t playing tricks on me again :v:
