What yous thinks up with this wanna iron out the problems early

[stonedmick]

It's a white widow in biobizz all mix soil under a cfl temps and humidity are good no nutes added yet. Any help greatly appreciated

 

[stonedmick]

I've had this problem before on plants but not this early and I can never get to the bottom of it can't be nute burn so I'm baffled unless it's pH or something

 

[WubbaLubbaDubDub]

What are the temp and humidity?(you just put up)
How many cfl bulbs you using, how many watts?
What did you water with tap water or R/O?
Do you adjust your ph?

 

[stonedmick]

Cfl dual 300w tap water just what pH should the water be before you add to soil

 

[Stealthstyle]

7 for soil 5.2-6.3 for hydro

 

[WubbaLubbaDubDub]

Your gonna want to aim for 6.5-7.0 ph in soil.

if im close I wouldn’t mess with it but I’m in organic living soil, as long as there’s no chlorine or chloramine I’m happy.

 

[stonedmick]

Thanks so bar ph is there any other reason for the browning leaftip

 

[WubbaLubbaDubDub]

Could be ph playing a factor.do you know you ph?

Have they gotten too dry between watering?I've seen dry fried leaves when forgotten about too long.

Do you spray them with water? Could get burned with the lights on? I’m just pulling at strings here now

 

[stonedmick]

Gonna check ph in water soon thanks for help

Have they gotten too dry between watering?I

Answer is YES! This is underwatering damage (or it was in touch with something hot).

Thanks I'll give them a good soaking and move light a bit further away see if it helps I PhD the tap water it's 7.4 is that high enough that it needs to be altered or should it be OK for now have no pH down at minute ill get some asap
