Can anybody help me? Im seeing brown dots on yellowish leafs. My plant is Shot Adrenaline Auto.
I thought I overfed the plant and flushed with tap water. And for one week Im not watering.
Please help me to solve my problem.

Is this just one plant?Have you been ph,ing your water?What are you using for nutes.How old are they and when did this problem start?

Hey Etreme!

She's looking a bit sad

Seems like you have very light yellow leaves (which sometimes suggests underfed) and crispy tip burn (which often means over fed)

How old is she?

I would take a educated guess that the PH of your medium (soil? coco?) is out of range for nute uptake. At some point it was in range but too strong.

If this is the case, you'll need to get a reading of the Soil (or coco) PH - there's a few different ways of doing this, but here's an easy one i use for a pretty good idea .

PH Calculation Guide by GoAuto6

Rough Calculation Guide:

Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference

If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.

For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5

If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5
​

If you can get a reading of the medium - we can try and correct it for you.

You'll need a digital PH pen for this (and for most successful indoor growing) - Without one it's all just a guess. (which would be a bit random)

If you put loads of tap water through - then the chances are that your soil PH will be close to your tap water PH. (and if that's in the UK it's likely to be between 7-8 so you'll need to lower it somewhat before theplant can eat the food... 6.2-6.5 in soil. (Shoot for 5.8 in coco.))

Hope some of this helps

All the best

Thanks for replies guys. This is my first grow so I may not answer all your questions.
This is shot adrenaline auto from samsara seeds in 12 lt soil. Its almost in her 3rd month from the seed. I was feeding her with BioBizz Grow and when I thought its flowered (3 weeks ago from now) I used Bud Ignitor as adding to water. Because its been long time to grow this girl, one time I mixed Bud Ignitor and Bid Bud in the same watering. Than next days I saw little yellowish on middle and bottom leafs tips. And some old leafs become yellow. Than I thought its overfed and I flushed with about 30 lt tap water. (PH 7). Than till today I didnt watered my girl. For a couple of days my girls started to have brown dots on yellowish leafs. Today it was 6.5 ph before I watered and now I checked ph is showing 6.0. Im afraid this brown dotted leafs are getting increased everyday. Im afraid I will loose her afterr 3 months. She was very healty looking till I used bud ignitor and big bud together. Im sorry for her now.
