how can you asume it is lime issue? you have know what you got before you can fix,right off .Hello friends. My plants are strain LSD. They are now in about week 12 since sprout and week 1 of flower. The yellowing and drying old growth, and yellow new leaf tips, have been a chronic problem. (I added dolomite garden lime, and not dolomitic lime to the soil, See here)
I water when the leaves droop which has only been about once a up until now. Going forward probably every 4 days. Each time I water a plant gets 1.5 gal, in 5 gal pot (soil). pH I estimate at 6.1 - 6.4 (varies).
A user suggested epsom salt and miracle gro fertilizer for acid loving plant. I only used them once at low concentration.
I use the fox farm trio for nutrients. To one gallon of water I add:
Big Bloom worm castings almost 3 tsp always,
Grow big veg fertilizer, 1 tsp tapering off,
Tiger blüm flowering fertilizer, 1/2 tsp first time last watering (tapering up).
Incredible, right? Sometimes I'll throw some Epson (R) salt crystals in there, but I'm a-scared to go overboard. I'll probably water tomorrow morning!
I suspect I have calcium or magnesium psychosis from the lime I added early on. The leaf stems have been purple for a while, I thought that was from LED lights. Now, in the pictures, I can see some of the main stems are getting red stripes.
Any suggestions on hOw2FiX? I pH with drops, I stand up to pee, and I don't have an EC meter. The plants get tap water. I am authorized to distribute up to $250 in my own personal scrip for the best suggestion. Thank you.
Just FYI pre amended soils like yours take a while to activate the lime in them. It would be expected for it to be low out of a fresh dry bag. Takes about 2 weeks and then check the ph again after you wet it the forst time.I assume it's a Ca or Mg imbalance, or lockout, from the "fast acting lime" that was "derived from dolomitic limestone" (printed on package) that I added early on.
Why did I do that? Because I sampled some runoff water and it was like in the 5s. I added the lime and soil slurry was right at 6.5ish. I've learned since that people say it's pointless to look at soil runoff water. Haven't done a recent slurry test because no distilled water.
I assume this is the problem because that's the only thing I've done differently. I added the lime to new FFOF soil. Beginner's mistake. The yellowing lower leaves and necrotic spots look like online resources for Ca toxicity or Mg deficiency. But I don't know!
I got rid of the pH meter because it was garbage. Could never get a constant reading, even when new and calibrated; the number was always different. I don't have an EC meter because I'm poor.
The lights have been about 30" away until recently, when I switched to flower. I lowered them to 20" and increased intensity. I'll raise them back up.
I will get new flower nutrients if and when I get some money. For now I just have the FF trio and epsom salts.
I will try watering again today with plain pHed water and some epsom salt (which I have used very sparingly until now; based on another recommendation). Any more help is appreciateed!
(Edit: maybe I'll throw some tiger bloom in there, too, since someone said they look hungry)
And BTW I'm not offering US dollars, just my own personal currency which has a terrible exchange rate. It was a joke: I am poor.
As I said above, I don't think your pH is way off. Lowering the lights to 20" + being hungry for Mg seems to do this in my grow. Your plants otherwise look very good.

Have you been periodically giving plain water with some runoff?Hello friends. I must be in week 5 of flower and I watered today. Here's what the worst leaves looked like. I cut all of them off. I watered with (per gal) 1 tsp Grow Big, scant tsp tiger bloom, 2 tsp molasses, 1/2 tsp epsom salt.
If you think of something I can do different, let me know! I'm out of tiger bloom and will have to get a new supplement.
(Please note that for these pictures, the plants were very limp and needing water earlier today)
Unfortunately I've used all of my good soil (just as well, I added garden lime to all of it which was apparently a no-no). I will purchase new Soil when I'm able. Thank you for the tips.Have you been periodically giving plain water with some runoff?
I might be way off the mark here, but there's a fair amount of room on the pot. You could try a top dressing of fresh ocean forest?
Being soil, a large plant and looks as though been in that pot for a while, it may benefit from a little organic matter.
Don't smother it, though I don't think an inch or two will hurt. It may even help a little.
I can't really make that call myself, as I haven't used the product before. But in general those liquid organics work more as a nutrient supplement. I wouldn't rely on them as a source of organic matter.Unfortunately I've used all of my good soil (just as well, I added garden lime to all of it which was apparently a no-no).

I do water with plain water alllmost every other watering... I don't water very often though so I want them to get something.
I think I will start watering more often. I water once the leaves start to droop--pot has been very light for a day or 2 at that point.
Edit: as to your point about organic matter: a fellow here directed I should end the use of FF Big Bloom (worm and bat poop). The fertilizer guide days to use it throughout grow. Should I resume adding that to water? (Even 'plain' water?)
