Yellowing and dying in late flowering all over plant

[funkervogt]

63 day old bagseed in FFOF soil, 5 gallon buckets. Transplanted 1 month and a half ago.

This is not just bigger, older fan leaves. This is started happening about a week ago room-wide and looks exactly like this plant. I have fed them nothing but Ph-adjusted (6.0) water before the incidence.

Gave them a bit of micronutes and nitrogen after (Fox Farm Tiger Bloom) and they perked up. Since I've been, again, feeding nothing but ph-adjusted water. The problems have continued but at a slower pace.

Any thoughts? This is not nute burn, I promise, if anything this is lockout or a deficiency. I have have not fed them anything but a light feeding of FF Big Bloom for 3 weeks, plus the light feeding Tiger Bloom a week later.

Are you adding cal-mag every watering?

 

[funkervogt]

... no. Each watering I add an 'organic' ph-down as my tap water PH is very high (around 8.0). The Ph-Down formula is made by a company called "SafeGro" but does not list their 'organic' ingredients, just says it contains natural acids.

It doesn't look like a mag def cause the veins are fading along with the leaves. My tap is ~8.0 but I still have to use calmag cause the the ppm is only 10 to 15. Have you checked your tap with a tds meter?

how bout the fact that you havent givin it any food?

kinda a no brainer

nothing much you can do now if your going to harvest soon

next grow feed them bitches

also stear away from fox farms soils too heavy you need to cut it about 50% perlight

you might wanna go to a soiless media and add your own nutrients if you want to go that way but ffof doesnt have enough food for a whole flowering season

 

[funkervogt]

Dr G - I was definitely feeding, but about 3 weeks ago had what looked like a nute burn so stopped feeding.

These girls will be around for another few weeks, the earliest at about 2 more weeks. The trichomes are still almost completely clear.

nute burn or lock out

cuz nute burn looks like burning

lock out looks like defencies

the onyl difference if the color of the dying leaves

and not feeding would looks like a lock out and you look like you have a lock pout but to me its from not feeding you dont have any browning pistals which would me burn

so the only way to tell is what the soils ph is if its fine its under fed if its not its lock out

deff not nute burn
