Why did my plants not grow the same height? With pictures

Tl Dr I did not cover the rockwool from light for one month I believe the roots did not grow out of the Rockwool and I stunted their growth what do you think?


Hello I was doing a hydroponic setup in an average room just watering free hand with low nutrients like 200ppm, I was away for one week and couldn't water them, they dried out a bit but even before this they were growing at different rates. They were I move them to an actual grow room.

I also had pH at 6.5 to 6.8 instead of 6 unfortunately. I'm using Advanced Nutrients connoisseur and after a month and one week I am switching the tank to the bloom.

I also think the last watering I used too much nutrients making the PPM 900 and maybe a caused nutrient lock. I just flushed the tank with regular water not as dechlorinated as best as I could. The ppm of the reservoir was 100 but then after I flushed it one time It went up to 150.

I don't have pictures from the side right now but it's very strange some of the plants just grew very small and then when I try to add more nutrients like the real amount they say they definitely got nutrient burn because all the leaves at the bottom started dying off and getting all brown and yellow.

I don't know how bad did I fuck up this grow?

Also as part of the grow light picture can you see how with the hanging fixture I lose about 1 foot of space does anyone know how to delete the hangers and make something that would make me have that one foot of space I could really use that for flowering if I could move the light higher.

Always go light on your nutes. I haven't yet used full recommend strength and still get nute burn. Start light and gradually increase your nute concentrations.

As far as the different heights... are you the same height as your siblings? If you started from seed, they are going to be a little different. Even if you started from cuttings, different exposures, absorption rates, can cause genetically identical plants to vary in growth patterns. Basically... no two will be identical.

Cant you tie your light directly to that wooden beam. Let it hang were it is for now but when they get taller tie it up on the wooden beam. Just make sure your able to do this still with out to much truble and without damaging the plants as you need to be able to get to the light and beam

I'm not sure how hot these lights get. I was told they are 40% less heat then a regular gavita 1000w de.

It heats the room temperature from 40 degrees to 80 with both lights on. I probably don't need to run it at the highest level right now since it's not in bloom I probably should have considered running it at a shorter wattage maybe the plants would not like all the height light right now I don't know I tried to research as best as I could I think it does say a bit last Light

Thank you for that advice about the Rope I'll try that with a thin rope I hope it doesn't burn anything I didn't want to put rope up against the light fixture the board maybe it's the wrong idea.

I could swear i see a shorter node spacing on the left plant. You didn't say what strain or even if they're the same strain. My guess would be pheno expression of an unstable hybrid.

They are Bruce Banner number 3 from gelato seeds dot Com I wanted to take a chance on them I never heard of them before but they ship from Los Angeles. I think for these plants did get really strong with a silica I added on top of the grow nutrients stems got so thick. I would like to say when the germination happened the stems got really long and lengthy I don't know why that happened I had under nice light and water. Maybe they just were starting to grow huge but they stopped off. I have like four big plants that are really nice in like all the rest of them are small and thin with really thick stems.

I know it's too running it hires the room temperature from 40 degrees to 80.

Thread some decent rope through the hangers on the back of the ligh and tie it over the top of the beam. I think if you leave a 3-5inch gap between the beam an the top of your light you'll be fine.

Ohh!! Thank you very much I will do this at the time that you said when it's ready.

Is your middle plant getting the same amount of water as the rest as the rockwool hasnt gone green at the top like the rest. The rest look like they've done really well since last time I seen them.

I suppose you could top the taller plants wich will give the rest a chance to catch up in hight. The ones you top will bush out more if you do this, so just beware of that and plan for future bud growth and air flow between the plants. Some of your plants are quite close together. I suppose wen they start flowering if too close together you could always tie the plants outwards abit so as to give you abit more airflow inbetween the plants.

The middle plant happened to be a plant that I just transplanted and it is small because it wasn't getting any light and it wasn't really doing anything it was just out of a test plant. It's been looking like that by the way for 2 weeks or 3 weeks it hasn't grown.

Thank you, these are all very good points. If I do top some of these plants should I try to turn those tops into clones? Those would be some pretty big clones. I was made aware that these are supposed to be guaranteed to be natural female so they can be cloned. Do you know I bought seeds once from one of the major guys Growers choice and they turned out to be Auto so they wouldn't clone. I I'm on the hunt for a good place to get your Medics. I was picking Oregon seed bank they have a list of sellers

Yes you can turn the tops into clones. Just dont cut off too to much . As for reputable seedbanks im guessing your in the USA. Look for seedbanks that have been around for some time and have a good track record.

The U.S.'s generic game is a complete and total clusterfuck. Too many unknown breeder's claiming they've bred gold and you get something like that middle one. So far I've ordered from the Netherlands and UK. No problems getting them to Oklahoma. And my girls are awesome here's one from Amsterdam, and one that came to me from Spain through the UK.

Thank you for your information. I'd like to point out that the middle one was actually just a plant that's only about a week old or week and a half I started it very late.

I'm sorry, I have to laugh at myself...I didn't really even see the little one, I was talking about that long stretched out one beside it.
