Straighten out my head: OK – my first grow is heading toward harvest. The second grow 12 girls are making me crazy. Seems each plant has its own issues. Yellowing leaves, strange leaves, all different growth.
I don’t know the best way to attack each issue. Do I do something 'en mass or treat every plant differently? They all grow in the same environment. Same light, temp, RH, feed and water.
Help – can you hear me slipping down the drain with the runoff? 
You have to treat each one different. When starting to grow new your best to stay with the same strain when doing that many plants and hope they grow similar. I only do four different ones at the same time and that can be a challenge sometimes. One needs way more food than the other 3. Another will have a dip in pH. 3rd lacks nitrogen. It can become quite difficult to keep up with them if you’re not dialed into your growing style.
I would get 12 different water jugs and label them to each plant and then target your attack fixing each plants issue.
I am reducing from a zillion down to six, this week and 4 next.
You are so correct, many issues and each requires special attention.
We will do better with a foursome or threesome, because, did not win Powerball last night.
Start by watering them all to runoff. Collect the runoff from each one and test it individually. See what the numbers (pH and PPMs) tell you about that plant.
It may be that some are just more sensitive to the soil and nutrients you are using. They may all have a bug infestation that looks different depending on how/where the bugs are. They may all have root rot or nutrient lockout and are displaying it differently because they are all different phenotypes. There is no way to know until you can rule out the obvious answers.
PH and PPMs on each plant, individually, will tell you a lot more than you know now. Once you know that information, we can likely help troubleshoot better. But for now, you will have to look at them all as separate issues - we can revisit that as a common issue, perhaps, later down the road.
I knew this was the answer – but hoping for an easy way out. I just watered/fed today. So, I’ll wait a few days and I’ll just wash everyone out and see where I’m at.
I don’t see any bugs, mold, rot – but I know nothing. I’m just like Schultz – “I know nuh-think.”
These are all the same strain – and all from the same genetics. White Widow Auto. Interesting suggestion on the watering jugs. I really only see three or four plants that seem to have “issues” – just like a woman, right? So, I’m going to attack – one by one.
Here we go…
I’m not sure I know either @CurrDogg420 
The one plant freaking me out is the Zebra leaves one.
Nah, I think you’ve just got a bit of senescence going on. Starting to show her fall colors. I see trichomes on the yellow parts, if the leaf was actually dying, those would not be there.
@GrnyGrows are you keeping a calendar or log of your grow? I find it invaluable, my senior moments are stacking faster than the pistols on my ladies lol. @PurpNGold74 is busting my chops about a stoners memory/mindset lol. Bet he’ll have some great pointers for you. Let’s see….
Lol thanks for the tag my guy.
I agree with the stoners above. Try to troubleshoot one at a time. Diff plants want diff things at diff times. Also pH could be varied across the different pots. So one size wouldnt fit all more then likely.
Can we see a diff leaf shot of ‘zebra leaves’ and the one with the purple boxing leaves as well
Yes, I keep copious notes and journals on the grows. I designed weekly grow charts – the whole shebang. I’m just so new that I don’t know what I’m seeing most of the time.
Which purple boxing leaves? Not following. Zebra is looking a little more normal today. She must have like the nutes feed yesterday.
things do work themselves out
This is the whole plant – she’s wild. Grows crazy and now is sucking up her nutes. I’m going to give her a little more food – and I need to do a run-off and slurry.
She honestly just looks a bit hungry. Let us know when u get the runoff numbers
