Hi guys,
I've just started my first grow, I started about 3 weeks ago. It's Afghan Kush from seed, all germinated great, through seedling and re-potted into 2.5 gallon pots, no issues.
The tips of the leaves are now starting to go brown, and it's happening to all of them (growing 10, hoping at least 5 girlies!).
From the research I've done it looks like nute burn, I've since flushed twice and not used anything but water for over a week but they seem to still be getting worse.
The only additive I've put in the water is Maxicrop Seaweed extract (liquid), which isn't really nutrient from what I understand.
I'm growing in organic peat free medium priced soil, unfortunately I cannot remember the name and the bag's gone now.
I have a cool air feed in so the temps in the tent are around 25degrees C.
The only thing I can't tell yet is the PH of the water as the ordered PH tester hasn't yet arrived... However, the water here is very soft so I don't think it would be drastically either way from neutral.
They are growing under CFL lights, 1x250w, 1x125w, 2x115w and 2x105w, so 815w of light, mostly 6400k but the 2x105w are 5500k.
Will be moving onto 600w HPS when the time is right.
Please have a look at the pics and share the wealth of knowledge I know is out there!
