Hi, New to the forum so bear with me. 2nd grow same problem, yellowing of leaves at tips that spread randomly throught leaves and kill them, At the moment all the leaves are yellow at tips some larger fan leaves have yellowed and fallen off.

1st Grow I used different nutes but for this grow...

indoor (closet grow)
Hempy Bucket (perlite vermicultie)
Tap water (hard area)
Started from about week 3 of veg
Using Lucas Formula (GH Hard water) 3 plants 1 gallon nutes then 1 gallon water over 4/5 days, plants 2.5/3ft high
PH down to 6.2 both nutes feed and water feed
600w lamp 4ft from top of plant
Exhaust fan positioned to suck away from lamp (works well) and a free standing fan

Any ideas appreciated, at the moment Im supplimenting with epsom salts as a friend sugested a mag deficiency but after 4 feeds with epsom salts problem is stil lthere. Thanks

I would look into nutrient deficiencies at Revised: The Complete Guide To Sick Plants,pH and Pest Troubles - PlanetGanja.com (http://www.planetganja.com/highsociety/showthread.php?t=8778). Looks to me like a micronutrient problem. Hope it helps! :thumbsup:

Locked out from nutrient buildup/salting of the medium.
Can you flush those buckets with plain fresh tap water- is there a way to do that with Hempys? Then re-fill them at pH 6.0-6.2 and go back to your normal routine.
The few VERY yellow low leaves are just from lack of light and do not indicate an issue. The burnt tips and other pale leaves with dark veins say 'lockout'.

Hey Stinky thanks for the reply. And also appologies phatsesh101 I missed your post somehow! Ive lowered my lamp more. Thanks

Stinky, I nute feed with Lucas formula (GH Bloom & Micro) 1 Gallon then I feed with 1 Gallon regular tap water ph'd to 6.2 2 days later. I will try another flush with regular water (2 in a row) to see if it helps. Thanks
