Leafs are turning bright green some burn tips

[StevetheGrower]

Hello guys and good evening.This is my first time growing weed in a grow tent. My 3 seedlings are doing very well seeds from RQS but the one Royal runtz had some problem. he is slower than others but that isnt my problem. I have noticed that his leafs are turning bright green and it has some small burn on the tips of them. I dont feed them anything rather than Tap water with 144ppm
I was wondering if i overwater them so i backed off some waters and if is it the Ph of my water tommorow i am going to by a Pen for ph so i regulate it.
I grow on Coco with perlite temps are 25Celcius with 60% rh and my seeds are Autos in 5gal

Give me your opinions whats going on and i am open for more infos
Thanks In Advance happy grow.

Indoors or outdoors?

If indoors what kind of light and how far away are they from the plants?

 

[StevetheGrower]

Hello my dear friend Its indoor grow with an Fce3000 300w dimmer on 15% lux meter is about 6300-6500 above 40cm from the top leafs

They are almost on second week after they got above coco i have no idea but i water them with tap water that i dont measure exactly the ph. now i have a formula for ph 6 to regulate the water ph

I'll wait for more seasonal LED users chime in with their opinion. I've seen this before when I put my seedlings under a harder light. I usually start my seedlings under CFL's or T5's. But I would think 15% intensity wouldn't be strong enough to cause this, but I could be wrong.

 

[StevetheGrower]

Okay my friend thank you. Maybe from ph could cause this ?? or nah

 

[StevetheGrower]

The other 2 that i have under the same light they are going fine maybe i overwater it or smthing :D

 

[StevetheGrower]

New update guys i regulate ph to 6.1 i backed off some waterings but still nothing :/
Any opinions what should i do may should cut it and start again with a new one seed or nah?
It is second week 14days old Royal runtz

I’ll have to go back an read what your growin in and what ur feeding
But what’s the white stuff on top ? Are spraying something ? Pest?

 

[Moshmen]

Ok did ya buffer ur coco ? What brand ? A
What nutes ? How often you water and how much ? Is there dry back ? And I’d drop that ph even further maybe 5.8 or so

 

[Moshmen]

Seeding should be under 5000 lux so dim that light just till we get true leaves then crank it up

 

[StevetheGrower]

No my coco is saying Bio bizz Coco mix With ec 0.2
I feed them with tap water with 148ppm and ph around 6 last 7 days before maybe it was higher. I was watering maybe once per day for about 300 500ml
What do you mean about dry back my friend?
Thanks in advance

I have it on average 6000 lux i ll dim it down. but after i water it it had slowed down his growth rather than his brothers which they are thriving

I had top dress with some more coco and perlite this is perlite :D left some dust on it

Dry back is basically letting the coco get to dry , sounds like your goin in the right direction give it a couple days and see what happens ?

[StevetheGrower]

Temps and Humidity are 25c and rh at 55% should i raise it low it ?

You need to feed them from day1 it's coco. There's no nutes in it like in soil
