Need Help Identifying Problem

[Skyler Patwell]

Problem: Leafs began to look like either deficient in something or nutrient burn not sure which. Day 71 of auto grow, looks like it started to go preflower but still does not even have full preflower pistols. Has started to gain new growth in the past 3 weeks of water only, but old growth has gotten worse. Dried out crispy leaves, large water leaves have pretty much all yellowed and fell off. *EDIT*
2:54 PM The leaves are also aimed really high up towards the ceiling of the grow tent even during lights off.

Medium/grow method: Home soil mixture. 3 parts organic compost/3 parts peat moss/ 2 parts perlite/ 1 part vermiculite. 5 gallon felt pot.

Feed: and supplements used: Earth juice Cal/Mag, Earth Juice Grow, Earth Juice Bloom

water source: Tap water filtered thru brita.

Strain/age: Breeder 710 Genetics, Strain :710 Cheese, 71 Days since seed sprouted out of soil.

light used: 2000watt LED (390 actual watts used.) Full spectrum with UV and IR. 20/4 light schedule until 2 days ago switched to 12/12 to see if it would have any affect.

Climate:78-82 Degrees F, 40-55% Humidity.

Definitely got something going on there. Good move on the 12/12. How close are the lights? Just curious. The experts will be along anytime now. @Waira In the meantime, what’s your pH and ppm’s running?

If that is a true auto it should be about ready to harvest at this point.See if the 12/12 sets off flowering but she looks pretty rough to make it at this point.

I know I messed up with nuits at some point but I've been flushing for 3 weeks straight water and it's getting new green growth mainly down low but a lot of it. My pH is kind of high right now I've been trying to lower it, from my slurry test it shows around a mid 7 and with my probe it's around a mid 7 also. I don't know my ppm have no way of testing right now this is my first grow and my other auto flower is already harvest and cured. Both received the same watering and nuits.

Oh no, that poor girl. I'm to new to offer any fix, but I hate to see her that far along and hurting like that!

You know, it might not be a bad idea to cut your losses on this girl. Start your next grow.

I just got a second tent and light, so I have my next grow going in that but I'm just letting it do it's thing with hopes of it flowering since it's so far along. I just need to figure out what exactly caused it because the other plant I had going both started on the same day but got the same amount of nuits and watering is done harvest and cured.

I think you found out what caused it already lol If both ph tests are coming back around 7.5 thats you're culprit locking things out and could definitely set her back if stressed.

-- severe P defc. mate,... some micronute defc. signs starting too,.. that soil pH is bad news, lock-out city,... light distance to tops? Water source, pH? Earth Juice is very mild stuff too, we need dosage and frequency info....
For sure this "auto", isn't so much (bad luck and/or genetics), your call to keep or force things... but nothing is going to happen until that soil pH is dealt with; a full on flush is the last resort here,.... 2-3x pot volume with low ppm water, checking run-off pH often... a TDS reading would also be very helpful, so at some point, look into getting a TDS meter....
