Weird leaf disease, Yellowing with orange stuff.

santacruz · #1 (**permalink**) 10-05-2009, 03:37 AM

Ok all my plants where fine until my GDP got this orange colored stuff on its leaves.

Normal leaf

then the leave started to get yellow to and started dyeing so I cut it and it spread to another leaf but wasn't to bad but I cut it too.

Then it started to show up on a different plant

Then I ended cutting all the bad leaves (about 2 or 3).

Then after a week it showed back up on the GDP

I am really getting tired of this. I need your help.

Im growing in ffof soil and feed 1/2 dosage of grow big and big bloom every other watering. and will switch the grow big with tiger bloom at flowering. I grow in a medium stealth cab and currently only have 75w of cfl until I hook up my other fan to the carbon filter.

Flush and then change to -feed, water, water, feed- kinda looks like in those first pic being the start of nute burn. One of the secondary nutes I think

I already tried flushing and didn't do any thing. It may be a calcium def.? What do you suggest jest I do for calcium?

Solution to fixing a Calcium deficiency
To fix a calcium deficiency you can treat by foliar feeding with one teaspoon of dolomite lime or Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will fix a Calcium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Or you can take crushed up dolomite lime or garden lime in a gallon of water and water it in the soil. 1 to 2 teaspoons per gallon of water, which will be slow acting. Garden Gypsum, which is medium absorption. Limestone, which is medium absorption, Rock Phosphate and Animal wastes which are both medium/slow absorption. Note: Caution when using gypsum to an already acid soil (pH that is less than 5.5) can have a very bad effect on different types of plants by effecting the absorption of soil aluminum, which is poison to plant roots.

Check for spider mites if the calcium doesn't help. Sure looks like the same damage I had. The mites pierce the cell walls and you get dead spots.
