Iv never fed any nutes that young ...

 

[Cannademik]

They're in coco. No nutes in coco.

There's some things you have to do to prep coco. Soak, rinse, prime it with nutes so in pH equals out pH. In general then you don't need nutes for this small. I never coco but learned a few things when I was thinking of. So search out starting in coco if you didn't already.

Can anyone help? Lots of pale green leaves. Some yellow tips on a couple of leaves. Also pale green spots on some leaves. (have treated with neem oil in case of mites).

Have 5 different girls growing with only this one exhibiting any major problems (all different genetics). This is after 6 weeks. The problem plant is a WW auto (12 weeks life cycle according to seed bank). Not sure if I'm overfeeding or under feeding.

I switched all plants to bloom nutes at same time (to keep it easy) so maybe the WW needs more N? Problem is I also upped the feeding in the last week because we had a fair bit of rain so I was worried about run off so may have overfed?

Thanks in advance!

Here is original essay thread for some background.

First time grower - need some advice.

Hi guys, First time growing. I've got 5 autoflower girls growing outdoors in 30L fabric pots. I used some premium potting mix (60% approx.) to a 70/30 coco perlite blend (40% approx). I germinated directly in the pots and didn't provide nutes for first 2 weeks. From week 3-5 I gave veg nutes...

Can you guys help me figure out what’s going on? My temps are 77* 60% humidity and running co2. I can’t tell if I’m deficient or in toxicity on my phos nutes and cal mag? I think I’m deficient on them but this is my first grow on week 6 of flower on my autos. (Purple lemonade and skittles)
