Hi Andy C,
The pic of the leaf you posted could have come off of one of my plants .
Had a lot of leaf die n turn brown, so picked them off. I was told it is a salt problem n to flush with water n a mild bloom feed.
Have been doing this seems to be going ok.
Good luck with your plants, Health n Peace

 

[anonymousgrower]

yeah, andy i'd just feed em with nothing but water for a few days and see how it turns out, make sure your waters ph is on track. . looks a little overwatered

 

[JamieShoes]

Mate I would say leave off the nutes too, like the others say. At this early stage they need next to nothing to get going healthily and there's probably more than enough in the soil to keep em happy


best of luck

Like JamieShoes says

 

[BurmeseDragon]

Flush with cold water until it drains less like a stinky pee color a brown like! Then rebuild roots, the plant is less of a concern than roots but not to much! Seems that feeding water is not going to get ride of nutrients without a drain! They usually require to calm down after a heavy down pour, it takes some season to get going!

 

[ANDY C]

cheers 4 your post, think ur right the soil is very warm and doesnt seem 2 b dryin out much,so iv made another intake 2 get sum more air flow..u think this will help????

 

[harveyj]

You should not need any nutrients for the first few weeks of the plants life.

 

[canniption]

yep,over fed and over watered.give em a break from both.with bigger pots they will take longer to dry out.good luck.

iv got sum semi autoflower seeds..... wot the hell that mean....???????????
