Lighting or Nutes

[Hotrod13]

I'm posting here as I thought it might be the best place, as I.m a newbie to this modern indoor growing stuff I expect to make a few mistakes, last indoor grow was over 20 years ago under fishtank grow lights..................

OK the Question I have one plant doing a test run in my fridge raised from a seed about a week old now I have 2 130 watt 6400 CFL's in the fridge one above with a batwing shade and one at the rear I noticed that my plant was yellowing The water leaves are completly yellow and the next set of single leaves have yellow tips? It is in straight potting mix and I nad it about a half inch under the top light I thought it was lack of nitrogen so I gave it some seasol yesterday Ot seems a bit darker green today but my question is about lighting in the old days you would have the tip of the plant nearly touching the fluro but these new CFL's I looked at the lighting chart and it looks like I could have it at least 12 inches under the light? at the moment I adjusted the lights so the plant is about 3 inches under the light and about 8 inches away from the rear light am I still too close?? or was it just a lack of nutes? I can get a pic tomorrow Thanks for any advice

Pics would help heeps, but i seriously doubt the lights r burning the plants being CFLS.....id put my cash on adding more nutes or maybe even over watering can cause yellowing.

Yep as PPG says, they likely want some nutes. Seasol is a root stimulator, not a nutrient

You can have those 130w fluros too close - I just fried some seedlings with them actually...

 

Seasol won't give your plant any nitrogen, better off using Powerfeed or specific hydro nutes.

[loylty gets u nothing]

pics will help

i used to have fluoros and cfls as close as 3cm from tips

but u have to watch em as they soon 3can get burnt

another thought could be the lil thing is being burnt

wat was in the potting mix u used?

as i said pics will be very handy

all the best
