Hi all,

I've been trying to just read, and learn and figure it out, but not happening so far I think. Can I get some experienced eyes on this plant please?
Some larger fan leaves are getting yellow, crispy, brown and then dying.
IMG_6466.JPGIMG_6468.JPG
The medium is promix/FFoF 50/50
Feeding FF trio to the label dosage.
4 day water schedule.One day feeding one gallon spring water with nutes, one day nothing, one day one gallon spring water, one day nothing. Spring water is America's Choice, think it should be around 70 -90 ppm tds.
We are 25 days since flip to 12/12.
Under a 600w sodium, plenty of air exchange, temps lights on 70 - 80F, lights off 65-70F

It has been doing this for a week. Throwing 3 large leaves already. This last watering I added a half dose of CaMg+ I was thinking cal or mag deficiency.
Help! if you see something say something. Thanks buds!

I am not sure if the picture is white balanced, but the leaves look too pale green. Would just hit it with FF GROW and get them all much dark greener.

Thanks sirs. I will try adding a bit more Grow Big, and continue watching progress.

Yes, the tent pic is white balanced. I will try to take a better picture today at lights on. The other two pics are regular house lighting, no white bal.

Since I am soil-less and organic-ish, I haven't really ph'ed anything. I'm going to get a hanna ph meter in a couple of weeks.

would you want to add a grow nutrient while flowering to fix this? I too am have WS 's problem but I can't figure out what's up. I will post pics further in thread.

I always keep it between 6.5-7 so I don't get how that would take place. My tap water is naturally good like that. But I always test before watering.

1st thought - it was nute burn ,but it looks like only fan leaves that are 'burnt-looking' n the rest of plant is really healthy,so I'd do as guys said n wait n see... looking good..!
Ps..why not do water only n miss one feed out..?plus I'd stop foliar-feeding,dont want bud rot or moulds etc..add small dose of epsom-salts for possible mg deficiency..just feed your soil n your plants will do the rest.Hope some of this helps you..

looks like a lock out to me due to PH since its showing multiple def's i would assume the lime in the fox farm finally got used up and it did the normal fox farm freak out PH swing that they are fairly well known for

Ps. See because you've foliar-fed them then had them under lights...that's what's most probably made them burn n curl like that..imo..that is..!

Should I clip the burnt stuff?

No i'd kp leaves on ,as the plant will use them n drop them when not needed..give it another couple of days ..mind let your soil dry a little between watering/feeding as this helps suck oxygen down to roots..they need oxygen too.!
If it doesn't improve then it's probably a nute lock out in which case you'll have to flush ...I'd give them two days of nothing at all,then flush anyway. Kp 'burnt'leaves on as your plant cannabalizes them when no food nor if they're not been eating due to nute lock out...!
.good luck+kp us posted..

It looks like your plant is moisture stressed. Your watering and feed schedule sucks. When you water it give it plenty of water till there is like a quart or 2 of runoff and then wait. When the top 2 or 3 inches of soil are dry and when the pot feels a little light then water it again. Water, water, feed. Don't give it anymore grow big and shit like that its already on the brink of burning. Follow that feeding schedule and youll be fine. Oh yeah and its NOT PH for Christ sakes.

And that looks like advanced calcium deficiency as well as magnesium deficiency, so that's why Epsom salt is not working 100%. Go to your local hydro store and get some cal-mag supplement . If you cant find it then water it with 50/50 water skim milk mix for a temporary fix till you can find something else

could just correct the PH issue ive had bloom nute def's crisp up too is what lead me to believe it was multiple def's its either p or k that crisp up the mid section of the plants older leaves cant remeber off the top of my head , the calcium is obvious from the spotting , the magnesium from the yellowing between veins , but the uber burn is something else
