Please help a rookie grower out

[Grownsince95]

Ok thankyou so takeaways from this are to move my fans around.
Feed more cal mag or just stay the same at 1ml/L?
The necrosis on the tips have just come on should I flush again for second day?
Also I will probably hang the lights higher up. Maybe like 3-4 inches ?
I believe my temp and rh are alright being night 18c and day 24c and rh between 58-66%?
I am also feeding once a day till I see runoff do you think I may be underwatering? Thanks.

You're using RO water right? What's the ppm/pH you're giving them now?

From what you said before your watering practices are good.

I am using ro water yes through a 3 part membrane my ec/ppm is 0 and then after nutes, it is ec 1.0 so ppm around 500-600 my ph I keep between 5.6-6.3 and really just keep it random as I know certain nutes are taken up with more efficiency at different ph levels

Should I continue to flush now or just go back to my nutrient mix ?

Yeah man that sounds almost perfect. I would keep the ppm the same until you get some more plant mass and just aim for 6 on the pH they don't love random. The roots will adjust it from there. Can't go wrong like that. They'll grow out of the wonkyness.

Flush when your runoff is more than 250 ppm from where you started. If it keeps happening you're feeding too much.

Tight nodes are a good thing and nobody likes a leggy plant but squashed into the pot by the light is also not good. I would raise it 6-12" or dim it. This will relieve some stress and let it spread out in a more healthy way.

The 2 most common mistakes a new grower makes is overfeeding and over-lighting. I'm not seeing anything that suggests that you're over-feeding your plants but I do think you're trying to drive your plants too hard with your light intensity. It's better to raise your light and allow your plants to grow up into it. It's much more gradual that way and much less chance of experiencing light burn/light stress.

As for temperatures, I believe your young plants would be happier with less of a temperature drop at night. 19c = 66.2F. If this were my grow, I would want to keep night time temps in the mid 70's so that would be about 23.5C-24C. Once they get older, the temperature drop at night will be much easier on them, and will actually help in bringing your flowers to the finish line.

I see the reason for this is I don’t have any heater so I am running lights in the night to stop a big temp drop if the lights were off at night aswell.
I am going to raise my lights now.
Thank you all for this help I was so worried thinking my plant was dying or on the verge of dying haha. I’m glad that isn’t the case I will keep you both updated on the final results of it thankyou both for your help!

Also one last question when do you think the root system will be big enough to place them 25l pots onto the auto pot trays ?

Never used the auto pots my auto feed is from above

They are far from dying ... what they need would be better described as a few tweaks. Nothing drastic.

Hold off on transplanting them for now. It's still a bit too soon.

FYI

This is how n toxicity looks

See all the leaves are dark & curled unlike yours

Ok I have made these tweaks I think I will send a pic soon of the update.
I have just fed them ro water with my mix ec was 1.1 ph was 6 I have then tested my runoff and the results were an ec of 1.0 and ph of 6.7 is this ok?
Also the pots they are in are already 25l pots I took the risk and transplanted straight from small seedlings pots to 25 l after roots had properly established I just was wondering when you think the roots will have grown enough to turn the auto bottom feed on?

I did exactly that lol and set my grow back awhile

Ok thankyou for clearing that up!

 

[TheGoldenRoad]

100% correct I was just overthinking it. Sometimes my brain starts making stupid connections when I'm stoned.

The struggle is real

Here's what I can tell you. Healthy roots grow quickly. There's no way I can tell you for sure if your roots have gone deep enough to rely 100% on the feed system. That's a call you will need to make.

One tip though ... you said you transplanted already but in the pictures I saw, it looked like the plants were way down deep inside the pot. Next time, use the whole pot except the last inch/2.5 cm. It appears yours are just over half full. I hope this doesn't become an issue for you at some point.

Hi they aren’t half full I did look not long ago and thought damn I should filled a bit more but I’d say they’re two inches off the top maybe a tad more. I’m going to post some pics of today after the changes now !

 

[Grower420John]

This is with the changes added do you guys think leaving the pots in this slight bit of drainage is ok I’ve been doing that and in the morning the water is usually gone as if the roots have sucked it up.
Also the humidifier mist sometimes directly touches the leaves of the plants is this ok?
Also was the above ec and ph runoff measurements ok?

I agree, pictures can be deceiving. 2-3" from the top isn't horrible. Some of the pictures in your first few posts make it look like a lot more.

Haha yes I know what you mean it’s all about the angles haha
