Top leaves floresent yellow

[LeeWill]

I am a first time unheated garage grower and built my own insulated grow box. I'm using 280 actual watts of CFL's on 4 plants and have maintain temp between 70 and 80*. I'm using FF soil and have added little nutrients to date. All of my plants look fine so far although I question this one. It took off fine but new growth now has a florescent, yellow on green appearance. The plant is 30 days from seed. It is a little stunted compared to the others. Is this yellow a sign of copper deficiency, normal for some strains, or what? This is a "mystery" seed from Nirvana. Thanks for any response.

What are you feeding them with? do you use plain ph'd water between waterings? According to Nebulas chart you have a zinc problem. Flush plants if you think you fed wrong it heals problems fastest.

Feed them twice with small dose of Miracle Grow. I'm watering with distilled. Will stop on the MG and flush.
Thanks

DO NOT feed the plants miracle grow. Start with Karlee's suggestions and wait about a week . Pay close attention to how any new growth looks. If it continues with healthy green leaves your on the road to a good recovery!
