If it helps any with the diagnoses I have been seeing this for last week or 2. Initially thought soil was hot or something. Newbie guess. Apparently wrong. But now I’m wondering if it was the early signs of what’s going on now? @Mpower11 what do you think? Referring to the tips of the leaves lighter in Color and slight turn.
Thinking it may be lack of food because the clones have showed no issues…. But then again the girl in the middle is still in a 3 gallon pot from weeks ago and just started showing the signs at same time. I kind of doubt the soils depleted at the same time as the one was in the 3 gallon a lot longer. As opposed to the others that went into 5 gallon pots. But it is also alot smaller. So the common denominator across all five is water. But then I’m wondering why the clones don’t show anything…………just trying to wrap my head around this. Water I’ve been using to feed is pHin around five now that I’m checking with this crappy pH pen the blue labs pens should be here later today and we can see for sure. Do I have to calibrate the pens before using them anyone know

Manganese deficiency? Looks a lot like it. Would the soil be depleted after 60 days? Not sure the plant uses to much but not sure the soil had to much

I got my pen but now Have to wait 24 hours for pen to hydrate in storage solution before calibration part of the way there

That sounds about right for Ro water
The real key is the runoff
I like the drainaway trays… then I have a pump pump it out of the tent… Yes Temperature plays a role in PH
Tip burn can be from your lights also… You plants don’t look like the soil is hot to me… But I’m still thinking it’s a Ph problem I could be wrong
Like I said before they can be hungry also testing your run off Ec correctly will tell you how hot / weak the soil is…
I always get my Ph solution of 7 drip it in for 5 mins if it reads close to 7 then your good… If it off I calibrate
You said you add around 200 ppm of Cal/mag per every watering so I find it hard to believe your missing Mag… Now your Ph can off and lockout Cal/mag… At that point it doesn’t matter how much you add the plant can take it up from the soil if out of range…
I haven’t heard of that before but if that is what it says in the manual then ok

Thanks I appreciate you being so through and responding @Mpower11
I was thinking manganese not magnesium it doesn’t look like it’s listed as a ingredient in cal mag. But I see it listed in other nutes.
Hopefully the run off trays make this easy as I haven’t done it yet. Hoping to slip them in but probably have to take off the scrog net. Thinking a garden hose should thread to them for draining and water collection
Yea was all ready to go till I saw that

Maybe that is what you do with pen vs probes. Probes have a cap with Storage solution already in them. No different than Grobo pH probe it shipped with solution on the probe.
I prefer probes so much better for me.
But learn something new everyday. 
Take note to keeping the sponge wet. Like I told you best case if you dry it out it will go to calibration worst case you’ll damage the pen forever
To me they look a bit greener today? Or am I wrong

I wish I could help you more there is a lot of things you can do but without knowing the data I don’t want to steer you in the wrong direction.

The might be Greener it seems
Like progression has slowed down hope to mess with them today after work again

Question how far away is your light… How many watts is it and are you running it at what % if dimmable

Light is at least 20 inches at closest point. Got a 400 watt vivo sun vs 4000 at 100% @Mpower11

What do you think should be my game plan at this time? Girls look thirsty but I’m still waiting on the drain away trays. Today is the normal water day

Quick update @Mpower11 ph pen is calibrated checked the water I was using (stored in plastic gallon jugs) phing at 5 from the old water filter. With new water filter it is producing water at 6.5 -7 ish ph so far it seem to be inconsistent. Taking different sample cups and different pHs. 
So I’m guessing as time goes the water filter degrades hence Affecting pH maybe? I don’t know this stuff hurts my head.

I’m using the advanced nutrients line supposedly you don’t have to ph your water it some how makes the nutrients available at a wider range. Or some how adjust them there selves ever heard of this? I have only fed them the one time with it so far and not much progression of the plant problem since. Kind of think it helped.
But what do you think of the not having to pH the water with the stuff? And I’m wondering if I did pH the water if it would have some type of an effect with it if it has other pH agents in it maybe? @Mpower11 sorry I know it’s a lot my brain just dose t stop

So I just got off the phone with advanced nutrients and they told me that the stuff I’m using has buffers in it to automatically adjust the pH but it also makes the nutrients available at a broader range of pH. So if I tried to adjust a pH to any level before or after the buffers would just automatically adjust it again. But they reassured me that the buffers also make all nutrients readily available and a wider pH range of something like 4 to 8 and to just water to 20% run off. I don’t know it doesn’t seem like the plants have not gotten any worse where they were rapidly progressing So I’m wondering if I just mix up a couple gallons of feed and give it to the girls and not worry about the PH like the manufacturers suggested. Either way I’m not going to be able to adjust the pH with this line of nutrients with the buffers in it 
They got a growers support line guy picks right up answers alll the questions so they at least got some good customer service

So I had to water the girls last night. Mixed up some advanced nutrients and followed the manufactures instructions regarding ph. And did not try to adjust. I’m really hoping I did the right thing. Next time I’m thinking I might go all organic. But we will see finger crossed. All signs seem to of stoped so far. That I can tell anyways. Want to make sure they have recovered and then prune them some starting to get bushy

Set up some drain away pans. Couldn’t fit 4 of the bigger ones in the 3 by 3. Now to find some type of pump to use to discharge run off. Work in progress. The girls still seem ok after feeding so far. Had to remove the scrog to move things around and elevate the pots some

is ranging from 6.5 to 7 u don’t have to ph at all
