Diagnosing this Leaf

2) Growing indoors
3) Watering schedule: every 2 to 3 days
4) Growing Medium: Soil - 2 gallon buckets (they were small plants when I started flowering).
5) What stage of growth: Week 7 1/2. This De La Haze is a 10-week-cycle plant (so far as I was told).


I have been using the municipal water supply to water my plants. I balance the pH between 6.2 and 6.7 (according to the color chart on my testing bottle). Five days ago, I stopped giving Flora Nova Grow to my plant and watered twice with water. I took these pictures today, and have just fed them for the first time with Sugar Peak Flowering.

I think my buds look good for my very first harvest ever, but I don't have much to compare to. Any thoughts on the brown spots? Any suggestions?

Yo,

Do you have an EC meter?

I'm gonna stick my neck and say you've got some calcium / trace element issues . . . . now whether too much bad municipal water calcium (molecules too big to be any use to a plant), or not enough good usable calcium, because you may have soft water, just not sure . . . .

The cupping is either Calcium and/or more likely heat related!Are the top leaves brittle?

Like to know the EC of your starting water.

Does the sugar peak flowering have all the trace elements in it like Flora Nova does? If it doesn't, I'd carry on using 1/2 doses of Flora Nova for a few feeds, see if that helps . . . .

I so not have an EC meter. I assume a standard volt meter/battery tester will not work?

My thought on continuing flor nova grow is that I don't need to feed the plants anymore nitrogen. Anybody know more than me in that subject?

I can get my hands on some bone meal. That would help with calcium I believe.

The leaves don't seem brittle to me, except the one that turned brown and died.

Hello everyone. I am also having a problem with a few leaves on the top of my plant. Could someone maybe tell me what it could be and how to fix it?

High

Nitrogen and the trace elements in FLora Nova Grow will be required throughout the grow if it's the only source of N, Trace and calcium, trust me . . . .

How long until you have to cut them down, three weeks . . . . .Flora Nova until the end of week 8 maybe 8.5 imho . . . .

Volt Meter . . . .no I don't think so, as there is no current running through the feed, we are measuring it's capacity to conduct electricity, not measuring the amount of energy in the water . . . .

Start your own thread with pictures from white light, with a run down of what nutes, PH of feeds, EC of run offs, temps humidity etc.

Then you'll likely get a more helpful response dude

volt meter won't help. too late for bone meal. plant looks pretty good. hard to say what the spotting is, but kind of resembles over fert. that leaf tip death is usually caused by too much nitrogen. hard to say. maybe go easy on ferts and just let it finish?

Hmmmmmm, OP, can we presume that the PH of the Flora Nova feeds and the feeds with the Sugar Peak Flowering are the same?

Wondering, as you've swapped from a mineral based to an organic based nutrient, whether it might of been an idea to mix them at half strength together as a sort of mineral / organic transitional feed, sort of thing . . . . less shock maybe . . . .

What is the EC and PH readings of your run off now?

I hope to get an EC meter by next week.

Semper Fi, I'm trying to do this as scientifically as I can. According to the chart from General Hydroponics, I shouldn't have been using the FLora Nova Grow as long as I did.
Am I correct that the plants use very little nitrogen when in Flowering?

Dude . . . . .that's a recirc schedule . . . . . you're in soil . . . . .

Have a look for the run to waste schedule. It may not differ much. MJ still uses N in flowering, it's when they ripen they need less, in the last couple of days to two weeks it can be cut out all together, depending on how heavy the feeding schedule has been.

For instance with my schedule, I'll start getting yellowing within 24/36 hours of just plain water, anytime throughout their lives, so a weeks worth of water at the end and I'm loosing leaves, perfect

I reckon guys we're witnessing shock from mineral to organic, is this possible, any one? Would love to see the nutrient breakdown of Sugar Peak Flowering; I know Flora Novas.



But can't find a breakdown of Sugar Peak Flowering. They do have a Sugar Peak Transition, which makes me wonder if we've skipped too much out just swapping from Nova to SPF . . . .

I know MJ loves just as much Calcium through transition as it does in Veg growth, and MORE magnesium is required once pistils start forming . . . . I wonder if Earth Juice Flowering has enough of these elements compared to the Nova.

Mix them 50/50 next time you feed, let us all know what happens . . . . . just keep PH of everything going in 6.6.
