I troubleshoot things for a living and that skill has been very good to me in growing cannabis.
I think I would start with one plant and give her a flush since it is requiring 100 gallons or so then introduce a small amount of fertilizer back on and watch how she reacts compared to the others.
What sucks is this is a slow observation process and your working against the clock because your plants are on a timeline for harvest
Thatâs pretty much what Iâm seeing Iâll take pics tn
Judging by your information, your pH doesnât seem to be the issue if you do indeed have a magnesium deficiency. Epsom salts and lime are good ways to add magnesium to your substrate if youâre sure thatâs what the problem is. If it only does seem like something minor, I wouldnât fret about it too much.
Tdubwilly provided some good links and if youâre really looking to refine your skills, then take his advice about experimenting with one plant.
Something to keep in mind is that when a plant starts displaying a magnesium deficiency, itâs actually been deficient for upwards of weeks, sometimes over a month, so the turn around time for healing in your plant would take a while as well.
Itâs manganese and potassium def Iâm seeing I also noticed it may only be on plants I had to use black strap molasses on when I ran outta hi brix.not 100% sure tho. But my pen was way off when I recalibrated it two days ago.lol
Tangilope is growing too close to the lights and lvpk is having that same problem expecially in the hot spots it seems wish I could raise my lights 
Suppercrop. Is that possible?
I already did a tonne of training and I canât get at a bunch of them since I have a screen on them now:(
Soil pH is wacked bad
ph between 6.5-7.5 !!! Yikes @tdubwilly @dbrn32 @Jess what should I use to help drop ph it will take me a month to flushIdk why itâs that high.???
Start watering with a lower pH, around 5-5.5. But be careful and monitor any changes.
How often do you irrigate your plants again?
Every 5-6 days
Agreed, although I wouldnât go below 5.5 and the next watering I would make a heavy watering
E.j . Says donât adjust ph unless itâs too low.i may have been brewing for too long as well as pen being off lol lesson learned haha
Fingers crossed for ya bro hope it all comes back together with minimal effort and issues
I just found a spot of pm on a blue glue #2 seedling this a.m. gonna freakin lose it pulled it and trashed it spraying everything again gonna pull all out bleach hook up new filtered intake and close all flaps replace plants and spray hopefully I can get rid of it completelyâŚ
Try spraying aact every 4 days it will occupy the leaves so pm cant
So far knock on wood but I havenât seen anything in the flower tent since the last treatment but plan on continuing with preventative u till buds start forming
Aact? What is it and where can I get some lol
I have some stuff called nutrol on its way its specifically for pm and labeled for use with high cbd and thc cannabis
