Burn from lights?? Need input

The only cheap solution that will ballpark things is the chemical soil pH test kits but thats a PITA to get soil from deeper than maybe an inch and I find them hard to read.
So I did a run off test on the blue haze and I was hitting 5.2 Jesus. I got it back up to 6.2 for now. I haven’t tested the purple haze run off since it’s flourishing.

Ive already spent money on building a 2nd grow box plus all the lights fans filter ect ect, plus a mix batch of new seeds. I’m tapped on cash guys. I get having every tool is super cool. Congrats to ya. Some people have a budget to go by. She will bounce back you’ll see. There are many ways of proper cultivation. 12 years of landscaping with my pesticide supervisor license for ornamental and turf, I don’t need every fancy tool to get a plant to grow right.

Right on op.

T-5 and Flors you can spray water NOT HID'S though. It's too early to feed whats in your medium? Did you mix it too hot? Do you have a fan moving air around her?

Check ph ( your locking out ) ... Typical calmag issue. Surprised nobody chimed in .
As long as you put the INPUT PH ( meaning what’s going in to medium ) , there will be no need to check runoff. Whether water only or feed as long as you stay stable when you add it .

Your pic is on left .... Calmag symptom on right.

Calmag deficiency? I should have her out of lock out now.

not too early to feed. Fed my purple haze at same stage. She’s beautiful. Don’t need fan yet either.

Looks great guys, always nice to learn. heres a handy picture i found that another guy posted! By using the diagram we can see its most likely the

I can't agree more with @Renfro on this. Trust me, he's taught me alot!. I spent around $440 for and Apera soil probe pen, and it literally saved my entire crop, and I usually run 100+ at a time. You did the right thing by feeding in at a higher PH to up the buffer result. I've had to feed in as high as 12 to get plants to buffer at mid 6's.. Sounds extreme, but it works. Just depends on what you medium is made up of. Mine was peat/bark mulch, and it wanted to crash the PH constantly. Once I did a couple of high PH feeding, I just had to monitor it and eventually I ended up feeding at 7-7.3 to stay over the curve as the PH crashed and the soil dried out between feedings. Knowing your true PH solves alot of problems for sure.. Rather than adding Cal Mag at a lower PH, your plants will take it up if it's in the proper range, and you dont have to add any more than recommended. It's saved me alot of time, frustration, unnecessary nutes, etc.. once you know your true soil PH, it's like you're on cruise control.

Man I like the way you put it.

YES! So many nutrient deficiencies aren't a deficiency at all but a pH lockout. When you know there is adequate amounts of everything in your feed, you really have to look at pH as the cause and investigate that further. I used to think that hey I am feeding at 6.5 so I am good. Once I got a good soil pH probe it was like taking off some blinders. All the mystery plant fails could be traced back to medium pH being way high or way low.

When I was running Sunshine mix thing were going great (didn't know about the soil pH then) and then one run things were all messed up and I couldn't figure out why. Then I got a proper tool and checked, bam my pH was up in the 8's across the board. Turns out they had changed peat moss suppliers and the resulting pH was much higher than before, many growers were having the same problem.

I used this method to figure out why some plants were growing all slow and had issues. The medium pH was way low. As @DoubleAtotheRON mentioned, corrective feeds work and they make an immediate impact on plant health.

What sucks is that Bluelab jacked their prices, that pen costs like $30 more than it did just a week ago. It seems to keep going up.

Just curious if you guys have compared results to a cheap one like this? I'm not sure you could trust the reading but maybe it would tell you what direction you need to go.

Definitely don't use that, POS. Use something like this, just don't drop it in water it will fuck it up and throw erroneous readings. When I can use it for a month and put it back in calibration solution and it's reading within 0.05 it's good enough. Quality control isn't probably very good on these but I've had success with them.

One meter will check all your plants. Take care of it and it will last. Never let the probe dry out and make sure to store it in the KCL solution at all times. Always pre-poke the hole so as not to damage the probe, the Apera is very sensitive to this and they sell a special stick to make the hole, should come with the meter IMO. The bluelab meter you can use the probe cover to make the hole, then insert the probe. Very dry medium will not give an accurate reading.
My BlueLab soil pen was supposed to get here today, but now FedEx says tomorrow by end of day, bastards, lol. I'm stoked though. I also ordered extra pH and storage solutions. $150 isn't shit when you do the math. I ordered mine from Growershouse since I have a hard time trusting Amazon for stuff like this. I tried to order one direct from BlueLab, but they were sold out back then, and now they are like $30 more. Growers House hasn't jacked the price up yet.

And, I can't wait to put my shit in cruise control too, lol. I know it's gonna make my life a lot easier when it gets here.

@PadawanWarrior .. It really is something you don't have to worry about when you get it dialed in... you can concentrate on other things like environment, light PAR readings, your notes, what kind of wine you want with dinner tonight... It just makes your life easier as a grower. Especially if you have a direct soil probe that can read soil and liquid both. I can mix up my 55 gallon tank in about 5 min, and just by doing it over and over again with adding everything in milliliters, I rarely have to correct my mix. I don't stress about ~50 difference in PPM or a couple of tenths off on PH because all the plants are a little off anyway in their PH. Good news, is you have that 6.3-6.8 window to work with. But, as I have said before, I tend to overshoot it a little... like I'll get a reading of 7 fresh and wet, the next morning it will settle 6.5-6.6, and start gradually dropping as the soil dries out. By the time they are ready for a feeding, I'll get a 5.8-6.0 reading, and feed again at 7-7.3 , and they will be in that "window" to eat as the PH drops and soil dries out.

DoubleA, join me on the sip train and you won't know what to do with yourself until harvest.

We are harvesting as we speak... not my favorite part of this biz, but it's got to be done!. The good news is that we are running 6 strains, and they all will not be done at once. We've taken 2 strains and they are drying.. Monday is the next take down of 1 more strain, then the last 2 should be done in another week or so. .... COVID19 has us stressing a bit, as we don't want our usual outside trim crew coming into our grow, but I think we'll manage (takes sip of wine)
