35k -40k lux at the tip of the plants, LED is already raised 100%. If I put them around 20-30k you think the plants would grow taller?
Am I suppose be lowering the water in the buckets regularly until I reach a certain height? 5gal bucket, 3gal water. Except for the Purple Haze which I took out 1/2 gallon so that is at 2.5.
I hadn't had the time to finish the rdwc but my plan is 2.5 to 2.75 gallons.
Keep water 1-2" below the net pot. At this point you can submerge em but let not try that here.
The bubbles are from organics or compounds in the enzymes. Not uncommon and not a problem.
Now here is the next step you need to learn. Water changes and when to do them.
The simplest way is say once a week but this is NOT good practice IMO.
Here is a method that will save you nutrients, additives etc, keep nutrient ratios in balance and ensure you are doing them adequate enough for the plants needs. The absolute main goal is NUTRIENT RATIOS. #1 PRIORITY!!!.
We will go over addbacks with nutrient additions after.
So you get yourself a little book and you do this daily.
Measure all add backs (by add backs i mean all water wadded to the res that is not done during a rea change) this should be done daily once they start drinking more. The goal is keep the water 1-2" below the net pot as much as possible. So each day you measure and add back water to bring it within 1-2 inches. Write it down in the book for each plant. These are your add backs.
Now you have 3.5gal of water in each 5 gal pail. So once you reach 3.5 gal of add backs you do a rea change. This will ensure you keep nutrient ratios in acceptable ranges. The more the plant drinks the more ratios can change as we have no idea if its taking up more nitrogen than phosphorus etc.You will find you can go 2 weeks in the beginning without a rea change. But likewise late flower you may being doing res changes as often as 2-3days.
I cant stress how important these calculations are. Its simple and great method of eliminating a lot of issues through the grow.
Always check ph and ppm after add backs.
Always adjust ph as needed, don't wait for res change days. I like to PH down to 5.6 then let it drift up to 6.0 before phong back down.
Now add backs with nutrients. This is used to steer ppm if you are seeing the plant is eating alot. I dont like going over 700ppm and while you can I find plants will grow, faster drink and eat more if the ppm is kept lower. Personally I find 600 ppm to be the sweat spot from late veg through flower.
So how do we steer ppm. You take 1 gal and mix double strength nutrients say 1200ppm. Thats your addback to increase ppm.
So let say you ppm was 600 and dropped to like 500 the next day. After drinking 0.5 gallon of water. You add backas much of the double strength to bring the ppm back up. Then finish topping up. You get the hang of it after a while. I'm to high to go through the calculations. But use a combo of the double strength and water to top up and bring ppm back up.
