Almost 3 weeks only inches tall under a 600watt

[Zero Hero]

Hi all,

I've planted three strains, Love Lettuce a mostly Sativa, Blue Budda and BC God Bud. I accidently nute burned them all but they have more or less recovered about a week or so back.

Some like the Blue Budda and a few of the BCGB are doing fine and some are not as expected from seed but all of the Love Lettuce never recovered from the over feeding. They don't die but they just don't get any better either. It's really odd and they have been that way for a week after flushing.

What could I try to get them going?


What's really odd is that a later shipment of the godbud that has just sprouted have taken off like a shot! Two of them are days old and as tall as my best Blue Budda. I do have a feeling they where looking for light but I also noticed the root has already gotten to the botton of the rockwook cubes. Even the one that was placed in the cube yesterday is already showing a root at the bottom.

I'll be really careful with my newest plants as I want to create mothers.

What should I try on the older weaker ones to give them a shot?

The light I'm using is a Phillips Horticulture with a balanced spectrum having blue and red. I'm thinking of picking up a HPS conversion bulb.

Is it the light that is keeping them short?

Thanks all.

I'll figure out how to get pics posted.

Well, need more details.

1. whats your grow medium
2. whats your nutrient schedule
3. whats your ph levels
4. how far is the light from plants (600w is pretty strong for lil seedlings)

any other info, room temp, humidity levels...
