Hail The Leaf's 4th grow...

Just sprayed everything with Epsom salts mixed with BMO Foliar Harmony...don't have any cal-mag....

epsom salts will work as well

I hope so, it's starting to affect other strains now as well...the pic of the Chiesel is a bit yellow, but the leaf has dark purple parts turning to yellow...

Ok, as of this morning the yellowing is worse than ever on the Lemon Skunks, Cheese #1, and ? Bag Seed...both Chiesels, and the 3 Toe now have dark purple, yellow and reddish patches on their fan leaves. Everything else is also now starting to yellow from the bottom up. I have no idea what's goin' on.

What is the pH of the water going in and the runoff?

Donno, never checked that...

No idea what it is going out, but going in it's very acidic, 6.2 or lower...time to start suing coal power plants for fucking up our rain.

The magnesium is being locked out due to your pH being too low
The plant cannot uptake magnesium from a pH of 2.0-6.4
pH is in the top three of most important things in a grow
You need to monitor your pH and bring it up to at least 6.5 or else the problem will only continue

Well fuck me twice on Sunday...I better fix that then...

Ok, I've adjusted the Ph with some stuff I've got for the fish tank, but I need a more natural long term solution, would putting a thin layer of lime on the top fix the water Ph issue over time?

Alright, I've been staring at pictures of sick plants and then at my plants for 15 minutes now, and I've got a goddamn nitrogen (Lemon Skunks, Cheese, and bag seed) and phosphorous ( both Chiesels) deficiency going on.

Does this mean I feed them more? Flush?

The Ph has been corrected and it's still getting worse. I've been feeding every 3-4 days days instead of every 2-3 because the BioTerra holds so much water and I STILL have a fungus gnat problem. Maybe they just aren't getting enough food?

I know it's " "ml per gallon, but how often? And if each plant takes 1 gallon of water, which they do right now, I've been waaaay underfeeding them.

Awesome, well, after correcting my own temporary mental retardation, I've now given the girls a round of the correct doses of nutes...it looks like I've been saving money and making my plants yellow by accidentally giving them 10-12% of the nutes they needed during flowering. Bloody christ on a stump. I now estimate that I will officially always be broke with the new estimated rate at which I will have to buy nutes. Holy fuck I'm going to need the bigger sizes. No wonder why my hydro guy wonders why I don't have to visit more often...

HTL, u have been under feeding them? how often do u water?
try using a balanced fert like 15-15-15 if its a nitro deff. and see how they do
also its good to use a low amount of nutes at first to get the plant ready for whats to come(full dose)

If the pH is off it doesn't matter how much nutes you are giving them
pH determines what nutrients they can use

pH was fixed, the yellowing and purple continued to get worse. I was giving the entire grow say 15ml of BioFlores, 2ml of Rhizotonic, and 10ml of Cannazym, etc when the card actually says 15ml, 2ml, 10ml, etc per gallon. I'm using at least 8-12 gallons to water/feed them currently. oops.

also what week of flower u on?
yellowing in the lower leaves is natural after about week 4/5
and yours plants are probably ready for full dose now

I'm on day 33, just over 4 weeks. The Lemon Skunks have been yellowing for a couple of weeks already, the Chiesel just started showing dark purple and yellow this week.

new pics? how bad is the yellowing? if its not to bad then it shouldnt be any problem, the buds getting bigger atleast?

Looking like you are going to be successful again.. Nice

Ok, for your viewing pleasure I got 3 of the girls out into natural light for a few minutes. Lemon Skunk clone #2, Cheese #1, and Blue Cheese. Keep in mind that alot of the dead leaves fell off.

looks normal probably lacking Nitrogen(N)
except on lemon skunk, looks like nute burn

any other opinions

lovely ladies by the way
flowers look fuckin good
