New Grower PH, EC, Temps??? Everything seems ok but look...!

[Builder0101]

Im not suggesting it’s best to use 24/0. Simply that due to my cold grow area. With temps dropping at lights out. I’ve changed to accommodate and rule out temp issues. I was 20/4 for 5 weeks and only changed accordingly.

I’m not saying it’s better. But seeing that autos are okay with it and peoplehave found no difference. Then I’d rather do this than run low temps.

I understand and I am not saying it cant be done. I have seen very good results where it has been done. I just question if everything is dialed in could the 24 be the limiting factor. Could it have been better. All living things need rest. The plants get some darkness most of their lives even in the extreme northern limits of their habitat. Very few actually experience 24 hours of light. Its north. It's not the north pole. IMO.

Coco uses Hydro ph levels drop ph down around 5.8 - 6.0 also I don't believe you can overwater coco. But @Waira would know hes a pro at coco among other things.

Yes growing in coco. I have been watering daily until a lot of run off regardless of how light the pots are. They definitely haven’t been near bone dry! I feel like every other day might be more suitable. They’re not very big in 8 litre pots. I think near a litre each has been overkill. The Lower 5th of the pots looks wet not just the underneath. And I’ve noticed small green spots on the perlite in the top. (Algae) I read somewhere these could be signs of overwatering!?
My EC runoff seems within range aside from two of the healthier plants and my ph is not even 1 higher on run off. There’s no burnt tips.

Yellowing in new growth like iron or sulphur def. Spindly skinny new leaves and then drooping and twisting leaves seems to be the main issues. And it’s on all plants. So im thinking it’s either overwater or cold climate. Otherwise it wouldn’t affect all three strains the same which clearly want different nutes???

What do you reckon?

I water every day 16-20 litres in 5 gallon (16 litre) pots. I do not have any runoff to speak of. A few drops. The bottoms get very wet. I take the plants out to water and set them on large folded towels. The towels pull the excess water from the bottoms. So I never have saturated medium. I think the plants appreciate the extra effort. I think perhaps the towel method will suit you very well. No more saturated bottoms.

I never test runoff obviously.

If you have excellent microbial activity they PH for you.

I dont think you have to worry about nute burn. You would have burnt tips by now I think.
Stay below manufacturers recommended dosage.
My nite time temps go down to 66-67f. Day time 80-84. Under LED. My humidity is near 50% 24/7. Veg and flower as I am a perpetual auto grow. I have some nice pulling of my late flower plants. I believe the lower night temps help bring out color.
The light new leaves is probably normal. All of my vegetative plants have lighter leaves. Takes them time to produce chlorophyll.
Growing out the same strain several times you will begin to understand its needs. Yes some plants are nutrient monsters. Some are sensitive.
I have a plant that I had to lower away from the lights. It just did not like the light as strong as the other strains. I could not get it green. I finally realized that whatever part of the plant was the furthest away from the light would begin to green up...

Put some mulch on top of the soil. That way you can forget about the green pearlite. you are not growing pearlite. Dont get distracted. pay attention to your plants. I'd like you to go back to 20/4 over a couple days and check and see if they are drooping the last hour or 2 b4 lights out. You want to hammer them with as much water as they can handle. Water is life. Dont make the mistake I did. I deprived my plants of water for 2 months. They looked happy the whole time but I know now they would have been much bigger. If they are drooping in the middle or beginning of lights on then it may be overwatering. I have a strong suspicion they will not. I just went through this. It was agonizing.

I water between 6.3 and 6.8 organic grow with coco. Plants are very happy.

I appreciate your comments and you taking the time to respond. My tent is in a cold garage in the UK where the temps are not above 10 degrees C. When lights are out (warmest time of the day) the roots are going down to 15/16 degrees C and then up to 27/28 degrees C lights on.

I have a 2000w oil rad and a tube heater and I can’t get it any warmer.

Im not choosing 24 hour light I’m doing it because I need to. I started and still believe 20/4 is better.

I will not change back and I will not keep giving water like I have because I believe it’s causing the issues seen.

I have 3 strains. With different run off values. Meaning they are eating differently but all plants are showing the same issues. Which means to me that it’s the environment they’re in or the amount of water they are getting as these are the only two shared effectors.

I’ve not fed them today or watered them. They were looking a bit more perky this morning I will feed them tomorrow with adjusted nutes and water them with less to equal around 10-20% run off and update this thread by the weekend with results.

My feed ph is always between 5.7 and 5.9 it’s the run off ph I’ve tested to go up to 6.3 - 6.7

I read coco run off is not accurate.

I read that aswell somewhere but wasn’t sure. I feel like that may not be a concern then!
