****HELP: Please help me identifiy this deficiency****

OK I received this Strawberry Cough a couple weeks ago from a buddy. She came in as a runt, it looked like lack of light from being crowded. So I took care of her and she came back to.

Well it's been a couple weeks and things are looking not so right. I have a deficiency of sorts but not sure what from. I use Techna Flora BC nutes and started her off at 1/4 strength but now use half to 3/4. My soil ph pen tells me Im at 7.5 to 8, but I did a test of my run off today and my SM802 ph/ppm meter told me much lower numbers. I'm not as fluent with soil as I am HYDRO so bare with me.

Im not sure how to attack this problem but would love the assistance and am all ears

...do you mist your plants while the lights are on? Looks to be spill burns or light/heat stress.

hahahahaha...nice jackass. Eat'n breakfast I see.

No I do not mist any. They are under CFL and a T5 but heat in room gets 80ish. It could be heat stress but none of my other 20 + plants are showing that ?

Thats Donkey he is guardian of the jungle

It does look like a splash hit the leaves except the burn crunchy one.

Ph in soil is very important and when you get above Ph7 stuff locks up tight.

I would cut food back to 1/4 and give her a good flush. In 5 to 7 shouls be right as rain.

Peace

So your saying cut nutes and flush ? How should I go about flushing ? Should I PH my water to a very low solution and do it as so or what ?

I would make sure your pH pen is right... Your friend have a pH pen? Test the same sample and see if you both get the same result. Flush the shit out of them w/distilled and stop the nutes for a feeding or two. They do not look hungry but more like the start of all hell breaking loose more than likely due to soil pH. Testing pH really blows. I never feel like whatever reading my "tester" says it's wrong no matter how much I spend on the stupid things. Fact is we never really know if they are right... What is there to compare to? pH strips are a joke and no matter how long I stare at the things it never really looks like ANY of the frigin colors on the chart. The soil tester, powder in a capsule things are the same. I have a Hanna pHep4 and every time I test Distilled water I get a reading of 5.5-6.0 and it is suppose to be true "Neutral" w/a pH of 7 yet I have NEVER got a reading of 7.0 w/distilled after 3 or so different testers. That 3rd pic in is the one that I saw that really makes me think pH. I have had my share of pH issues in soil and that looks like pH lock-up happening. In soil once shit goes wrong, your screwed it's that simple. What soil do you use and what are you watering with?

I check my meter with 1500 calibration solution and ph 7 calibration solution. I am not sure as to what soil is being used. I text my buddy and am trying to figure the soil out.

Figure 12 shows Phosphorus (P) deficiency during vegatative growth. Many people mistaken this for a fungus, but look for the damage to occur near the end of leave, and leaves the color dull greyish with a very brittle texture.

This condition is rare and usually buffered by pH limitations. Excess phosphorus can interfere with the availability and stability of copper and zinc.

Click to expand...

You flush / leech the soil with pure RO water with neutral PH, using two times one method.
1 gal pot, flush with 2 gallons of RO water / 3 gal pot, 6 gallons of RO water.
And then when they need a drink again, use 1/2 as much fertilizers you think they need...

They say you should flush every 2 or 4 weeks, I'm lazy so I push it.
