Found this when I was doing my water check...



I've seen several charts here and there, but hoping someone here had seen this problem before. It was an early leaf, second or third node on a RQ Critical Auto plant. The rest of them look okay. PPM's were @ 350 and pH5.81.
Doctor, Doctor please help me here

The "others" I was referring to were the rest of the leaves on that plant. There are 2 plants in a DWC setup. 6 quart tote that I fill with 3 liters of distilled water. I started feeding Advanced Nutrients Sensi Grow Part 1&2. VooDoo Juice & B52. First feeding was given 3 wks. ago @ 1/8 strength. 1/4 strength for wk 2. this Wed will be the 3rd wk. Water & nutes are mixed in gallon jug,with the pH adjusted then I aerate with small airstone for 12 hrs. PPM readings taken before and after.

Lights are installed horizontally and plants are approximately 4 to 5 inches from them. I'm using 3 5000K CFL bulbs @ 23 Watts and 3 2700K CFL bulbs. They are on a 18/6 timer cycle. Tomorrow will be wk 4 since I put them in the grow box. Heat inside the box has been as high as 83.7 and the lowest I since since the grow started 68.3. I bought a temp/ humidity used in Reptile Enclosures. It will record the H/L until reset or remove the battery for resetting it. Passive intake and I have a small oscillating fan inside the box going 24/7.

I clean the tote and the airstone every week. I have 2 totes that have been painted black, on the outside not inside, that get sterilized before the next water change.Alcohol wipes and then a hot water scrub left to air dry.

I have a few photos of the plants and the box over in the Small, Micro,Stealth Forum, or you can click on the link in the signature. I hope that I have given you enough info this time that you can help me out a little.

Thanks :joint:

Looks like it could be a nute burn but if it hasn't spread or spreading then it was some hiccup. I've found different strains need different nutes sometimes and that the reason I don't mix strains in my 48qt coolers (typically four autos) anymore. If it's not showing in new leaf growth and not spreading to the rest of the older fan leaves then it was just one of those things.

Have you grown this strain before? I'm just starting a batch of Critical Auto Mass and this thread caught my eye, I will have to find the sweet spot for these like I have to do on any new grow. I use AN Sensi Grow A & B and Sensi Bloom A & B.

Good luck getting those girls happy again. Sooner the better mate!

Thanks for looking in. I have photos over in the Small, Micro forum. Yes I did put two different strains in the same res. I hope that it was a hiccup, since it has very vigorous growth in the past couple of days. I have been feeding them AN nutes along with B52 & VooDoo Juice. I fed on the 19th @ 1/8 strength, 26th @ 1/4 strength. Wed will be the 3rd feeding @ 1/4 strength Sensi Grow A&B and B52.

I will measure tomorrow since Mondays are updates on the grow, Wed are res change & add nute water.

Thanks for the help :bigjoint:
