What is happening Here!

On Wednesday I switched the blue dream and Vanilla kush to week 2 nutes. Both are at 200PPM, PH of 5.9 Res Temp at 73f. It seems like the Blue Dream is still a bit light on color and that spot showed up this morning on it. It is growing really well. The Vanilla Kush seems to be getting a slight leaf curl up and the brown spots getting worst but has not spread to other leaves.

The room temp is 72f

Is this a deficiency? Rust Mold? How do you even tell the difference between the two :no:

BLUE DREAM ^^^^

VANILLA KUSH ^^

Your temps and pH looks good. To me it looks like they are hungry. That discoloration on the leaves are early signs of a phosphorus deficiency. Coupled with the overall light green color I'd suggest you up the strength of your nutrients a bit. If you're used to growing and feeding autos, keep in mind that photos can tolerate about double the nutrient strength of what autos can.

Last night i did a res change on the blue dream, and moved it into week 3 nutes, that put the PPMs up into the 280 to 290 area, After work i will do the same to the vanilla kush. I hope this stops the brown spotting. I was so worried that it could possibly be a rust fungus. I knew the most likely cause was defincent, but i needed some others input as to not jump to conclusions and make a problem worst.

Yea A4 i calibrate my ph meter every few days just to make sure its on point.

Thank you all for your input!

No, not a calcium deficiency. First pic is calcium, second is phosphorus.

So Muddy... do you think the corrections i made last night were a step in the right direction?

 

[Muddy]

I think so. Just watch your pH and PPM over the next couple days. If the pH rises and PPM drops, they are still underfed.

Update! Sunday night i upped the PPM's on the blue dream during the res change to 280PPM, she is still putting out brown spots!!!! this plant is only 2 weeks old, she grows fast! THis morning i added another 1 1/2 mls of cali magic to the res..... Should i move onto the next week of feeding?

Anyone have experience with this well known strain? is she a heavy feeder cause it sure seems that way. PPM's have not dropped since i did the res change on her. But continues to put out brown spotting.

Here is something i have thought about, i do have epsom salt, would it be advisable to throw about 1 teaspoon of epson salt into bucket?

How big are your roots? Are they into the water yet? Also, what were they started in, rock wool?
