Hi guys and girls I'm hoping someone can help with some issues I've been having in my tent lately.
I seem to be having a lot of yellowing going on with a lot of my fan leaves recently and I'm not sure what's wrong. From reading lots on the deficiency section I think it may be a zinc problem as the pics look very similar to my own and symptoms kind of relate as my girls have been through quite alot of stress.
Here's what I've been working with to give a bit more info
Grow tent in attic
Growing 2 strain hunters money makers, 1 afghan reg and a blue diesel auto in a pepsi bottle.
Afghan in soil with no noticeable problems at all.
The rest of the plants in coco.
400w hps with cool tube
240w of heat via 2 tube heaters
Feeding coco plants with liquid silicon, rhizotonic, calmag and bloom nutes which are npk 5 4 9.
I have been using ph down to keep my feed at 5.8 and currently have no way to measure ec.
I have been feeding twice then just ph. 5.8 water with a touch of rhizotonic then feed again.
Most of the leaves have a slight yellow tinge but some are very yellow and just fall of when touched.
Plants have all been 12/12 from Nov 3 and the auto in the pepsi bottle has been 12/12 from seed
If I've left anything out just ask
This is my first grow so I really am a bit lost about how to fix this problem atm.
Sorry pics arnt great there mostly taken under hps but could take a few pics after 8 tonight if needed. Thanks in advance guys
