Leaf problem = ?

[Ytka888]

Hey guys and girls, any thoughts on what could be reason behind this signs?

The first three pics of big green leaves are of the 3 plants that were transported a few days ago from other grower.

Small ones are going light green and develop brown spots.


All are under Timber Vero 900watt lights, but lights are dimmed to around 400 - 500 watts.

And I fed them all yesterday with the flora series nutrients. 2nd week.

Your feeding all of them the same level even though they are of different ages? Big leaves look to have heat or humidity stress (heat too high or humidity too low) but also have that overwatered/root rot/just transplanted or cloned look. Something is clearly off on whatever your feeding the seedlings. Not sure if the flora trio has cal/mag in it or not. If not that is probably the issue with them.

What medium are you using...coco?

I just read about it and you pointed it out too, I've been overzealous with spraying them with water once I brought them in, and guess had them too close to light.... so it might be the heat burn, as to humidity I have it on average at 60%.

Flora has mag/cal but I only fed them 2nd week schedule yesterday... I had little mite problem with two seedling that I had in regular soil I got from home depo, so I got rid of them and used Avid to water them.

You think if I used nutrient water yesterday to feed them, should I feed them just water today or continue with nutrients for 2 days and than just water for a day?

I use coco only for 5 plants, rest in woolrock

I'm ashamed to admit it, and yes I had that thought for not feeding them different way. I got the three big ones from a friend and yes they are clones. So will adjust the feeding as of now

I had a delusion that I might manage them all together my seedlings and this 3 bigger ones, before I have my second room set up for veg, and the one I have them in right now will be used for flowering. Guess I have to speed up on that one.

You think I should (must, I should say) I'd just the level of nutrients toward their age stage and water them with that, of first flush them today and than use it tomorrow?
