Good Question???


Ok so, these girls have had it rough so far. Are just getting over their root rot, due to this they are in day 35 veg and not very tall at all. Had them in a RO and H2O2 DWC to fight off the rot. 5 days ago moved them back into aero with half strength nutes. (changing to full strength tomorrow) They have been responding well and lots of new growth. This morning I noticed some leaf discoloration and some curled leaves. I think it is magnesium deficiency, so I added 15ml of CalMag+. When I got home from work, the curling seems to have gotten better. I think this problem occurred due to the fact that my res is only 3gal filled to 2 1/2gal, and i top off with only ph'ed RO water. I added a total of a gallon this week.


What do you think?? Did I guess right??

First pic is of grow room
Second pic is of my home made light
Third and Fourth pics are of the plants
Fifth pic is a close up of the leaf discoloration

Thanks for your time, and any advice you may have. :jointsmile:

Check out my grow log for more pics if you want http://boards.cannabis.com/grow-log/...-aero-dwc.html

Yep, might be the deficiency, it could be something else, early yet with the photos. I use only 10 ml of cal/mag in 5 gallons with my RO water. That seemed to fix me. But, I grow in FoxFarm ocean forest.

Does anybody know what is happening to that leaf???????:wtf:

Just realized my last post sounded kind of offensive.
Sorry if anyone took it that way.
