Please help. Ph problems, light burn or deficiency?

lamp wattage ? and distance from the bulb ?
og = light sensitive

soil or coco ? probably salt accumuations blocking assimilation of certain nutrients ( immobile nutrients)

Hello everyone! My one fire og plant has been giving me some problems recently, but also my other plants a little bit. A little background. Fire og started yellowing harder than all my other plants. Thought it was mag def so I upped the cal mag and gave an Epsom salt foliar. Didn’t help out too much. I recalibrated my ph pen and it was a whole point off. I was feeding them 5.5 instead of 6.5. I watered this time with. 7.2 to balance it out. The fire og just started showing some burning, and I don’t know what’s going on. Please help. Only the last photo is the gorilla glue. The GG #4 shows som mottling. Please help.

50/50 FFOF and Happy Frog. This is the distance, prob about 3 ft maybe more even. Wattage is “1000” and “2000” but they are amazon led’s so it’s not 3000 in total at all, I’d say maybe 600-800 watts

It's a nitrogen deficiency keep your ph between 6 and 6.4 back off the nutrients too bro feed half the recommended strength. For now let that pot dry out not too much but a good hit it with some lime with nothing but water for 2 feeds and you'll be ok and make sure that you're not over watering it which also cause leaf yellowing

Oh and since you're using happy frog with nutrients in it man do a feed feed water feed and on to flush some of that shit go to my grow journal and see my plants have no deficiencies at all veg for 2 months 17 days since flip here's a few pics bro. I use mostly peat moss with a mixture of miracle grow citrus soil not alot some perlite earthworm casting and a lil bit of manure and humus. The biggest is gsc and the other is gg4

I'm learning towards the ffoc and hpf compacting/ strangling the roots...had this happen before using that mix without added perlite

Also, what do you think is a good runoff ph to aim for every time?

Bro I dont check the r.o. its useless really because if you're doing everything that you need to do you'll be ok. Get a soil ph meter. What I've learned bro on my on also get sulfer because your soil ph will get too high during veg because you're not using many nutrients that lowers your ph in the water it spikes it and you have to bring it down so I'll hit it with the shit maybe a month in. Pay attention to the details of your leaves closely because you can see the discoloring coming very slightly before full blown. I say a very slight blue in my leaves checked my soil ph it was 7.5 so I hit it with sulfer and I was pretty green the next day. I've been growing a yr. Killed seedlings under watered under watered not doing what I need with balancing temp over nuet etc heat stress mold man everything but it got me where iam now and it's getting better. Just dont cut corners pay attention to detail and treat them like your children

Those cheap plastic, needle readout, two pronged pH meters available in garden sections, offer nothing other than wildly inaccurate, therefore useless readings.

If you are serious about a soil pH probe, that actually works, your looking at a far more substantial investment. Companies like Blulab, Hanna instruments....

Testing the runoff pH is also extremely misleading and inaccurate, those results should be ignored.

^This...

If you've been doing this over a period of time, and I suspect you have considering the deficiencies, one water with a slightly higher pH isn't going to erase your issue. Dial in your pH with the greatest certainty you can afford, then see what deficiencies are continuing, treat for them and be patient. Good luck friend.
