Grow Mediums I want to try hydro, you want to do hydro with me?

I have been running them for 24/0 until 4 days ago and then start giving them 2 hours off everyday. I see, as you say, a more droppy, drop just after lights on.
Ppms today were 383 to be exactly, can have a look in a couple of hours. But i know when i have had it over 400ppms, it raises slowly, but i have a big system and they dont drink so much.

Thank for taking your time. Im calmer then a freeze with ice

I am not sure how much to read on the pistils and budsites at this stage but they look promising and by the looks and sounds of it, it seems your feed is spot on for now.

Awesome. Thank you for that.

The base nutrients im using normally gives the girls signs of to much Nitrogen before any tipburning accur. Im pretty sure, as i see that 2 of them can have the same food as both are looking okey and growing with a nice green, whilst the two other ones are slowed down by the nutrients, showing signs of excess, one of them still have green cotyledon, if underfed she would have eaten them up by now i guess. I did lower the nutrients to 383ppms from 450ppm. Ive seen 300grams plants on web use no more then 0.8 - 0.9 EC max, even in full bloom. Ill take some photos of them today and explain what i see. Maybe i read them wrong and underfeeding them, then im happy to hear about it. I see how your girls look like at day 21, they are bushes.... so apparently im doing something wrong.

I think 2 of my girls will do okey, maybe 3, while 1 or 2 will hit the garbage.... or they can stay but they wont yield anything. . I just learned that i need to start up more girls in smaller containers and choose the ones that like about the same feeding before planting them in the system.

Rambo: You are not a fortune teller. Many plants that seem to start slow, look ugly and pewny take off and become the best producers. Now that is not to say they all will some are just duds. You already have time and money invested give them a chance.

I don't know, other than tip burn, any way of determining too much nutrients. If your nutrients are in balance a healthy green plant is all you are going to see.

I am a firm believer that plants need night time. They developed that way since the beginning of their time and you are not going to change their genetics without GMO. It also saves power/money. Now if you want to extend the growing period and still give them enough night 18/6 is what I recommend, you can run 20/4 by using 15 minutes of 730 nm far red light at lights out. This is called the phytochrome system. This puts the plants to sleep right away and they think they are getting 20/6. You can buy the far red lights in many places but Growmau5 has a cool DIY video showing you how to build one cheap. I included 730 nm SemiLeds as part of my DIY COB light system.

You are correct. I have seen it myself, the smallest girl become the best one. It has happen to me, thank you for that reminder. The slower ones almost always get biggest, possible coz they have time to build up a bigger roots-mass and more nodes before they get in to their explosive growth. Its kind of logical. I wil let them be, when i said i would bin the girl i ment that she would hang along with the nutrients of the others. This run will acsually be a facit by itself, as we know how they were in their younger age, and how they finished their life.
Thanks for the support.

Also, i remember i only run the light over the bigger girls for 3 days, and only secondary on the 2 smaller ones. That could play a big role in this.

Hey @RamboGarden I wanted to give you this video that might more easily explain the differences of hypotonic, isotonic and hypertonic solutions and their effects on plant cells. Perhaps this might be good food for the brain to understand why a stable EC / PPM or a tad falling EC / PPM is good for you plants as it ensures a good osmotic flow of water that ensures good turgor pressure that your plants need. Or in other words that your plant cells are turgid.

Thank you very much. That was an good video.
I did have a look at pop22 explaination but this was easier. Made me understand a bit more.
I will google and see if I can find some more videos about it, this was a very good and I think I will rewatch it a couple of times. Appreciate you are taking your time. Im picking up info from all the corners, I might become good at this in the end

Did a rez-change and raised nutes today to 409 ppms as the girls are in the beginning of their true veg. I have manage to get my water-temps down to 21°C.
I'm looking at the best of the girls and it looks like she will be big. Her nodes are tight and the growth from lowest nodes growing horizontal. What I can remember is that a good sign of a girl that will get a nice mass

So, after some youtubing I checked the girls and they have this kind of growth? Air temp is 25-26°C, water-temps as 20.9 °C....

Taco in the beginning of the leafs.. is it heat, light? Temps are fine since yesterday, this happend in the afternoon... got it on every lady, more or less.

 

[Journey Man]

I turned off the lights as I suspect this is from heat... will give them a few hours rest, possibly they got heatstressed just before I fixed the temps and this accurs now. Will raise RH again to help the leafs a bit on the recovery.
