Too much, or too little nutes? 35 days into flower!! please help!

[HGsmoker]

I'm totally confused by this. I've been doing alot of reading and keep finding different answers. I've seen pictures from people saying it's deficiencies, and others saying its over-fed. I'm using bottled distilled water with a pH of 6.5 along with 100% organic nutes. Usually watering every 4 days or so and feeding every 2-3 waterings.

On nearly all my leaves the tips are yellowed and curling and the outer edges on some are also yellowed with some yellow spotting. The older fan leaves have it worse but alot of my flower leaves are getting curling/burning tips. Also theres 2 select leaves with a large yellow spot that came overnight and occasionally a lower leaf with yellow and fall off.

Any suggestions are greatly appreciated!!

If i can figure out how to upload pics I have 4 waiting.

You can upload them to your gallery, you do not have enough post count to upload pictures to threads yet so upload them to your gallery.

Are you using micronutrients; you have to if you are using RO and distilled water.

How much are you using when you feed your plants? With how much water and what brand are you using?

Yellow leaves that fall off is nitrogen deficiency

There is no way it can be fert burn if you are feeding that low amount you are not feeding weekly sounds like they may need food.... what kind of soil are you using?

I had them in my gallery, it just wasnt letting me add them to my posts yet. Thanks though.

Anyway,

No, im not using micronutes, I didn't realize I had to. Any suggestions on what to get?

I'm using Iguana Juice Bloom at 30ml / 1 gal and Pro-Mix BX soil.

WHat are you using for lighting, one ofthe pics looks like it got to close to a fluro bulb.

As for the others; did this happen before you started to feed?

Since you are using distilled water and you are not using micronutrients you are starving your plant of micro nutes; distilled water has low ppm's cause it's got no micros or very little of them. Lets say you are using tap water; those micro nutrients in the water help suppliment the plant untill you feed it micronutrients.

Calcium and magnesium is a big one that is in water; but distilled water does not have it.

It looks like the problem you had was a calcium deficiency but it weaned away because it still progressed and was not fixed.

Your using a few tablespoons per gallon of your bloom?? Your plants look like they are a weird color green must be from using a lot of nutrients.

I would not use more than 1 tsp per gallon of water with that bloom nutrient.

For micronutrients get some earthjuice microblast and for dolomite lime for calicum and magnesium. Microblast does not have calcium but does have magnesium and other micros also have you tested your ph? You are using a soiless medium which means your ph needs to be that of hydro growers which is 5.5 to 6.3. Use 2 tsp of microblast every 2 weeks and stop using distilled water.

I've got a single 250w HPS (super agro) for lighting, I ditched the cfl's a long time ago. Planning on getting a 400w soon as I set up a new room. And those leaves are pretty far from the light, theres others much closer.

The reason I'm using distilled is because I was concerned what might be in NYC tap water. Particularly fluoride. As well as being told not to use it.

By the way, It's just one plant and it only looks that way because im lazy and did a half-ass job of color correction. Otherwise it looks a normal green.

And the bottle itself says to use 15ml / L. So I'd still only be at half strength. And heres where it confused me. There was a little sticker over the "15ml/L" that said "3.5ml/L". 14ml/G seemed to little once it got bigger and going by the 15ml/L, 60ml/G seemed way too much.

Distilled Water has a natural Ph of 4.0-4.5
De-Ionised has a Ph of 7.0-7.5
Distilled will be missing macro nutrients,yours looks like deficiency
Maybe try tap water and a little Ph down
I have used distilled water before but only for the first two week of grow from seed.

I had/have the same problem. I had it pegged as a calcium deff too - probably from a lockout in my case. I've been feeding it something with a low level of calcium and it's slowed right down.

Fix it quick though - it's caused quite a bit of damage to mine.

looks like classic tipburnings to me...eas up on the nutes

Actually, Im sorry i've only been using actual distilled just recently. Normally I use poland spring which has a pretty constant pH around 6.5. (The distilled does too though)

He is burning them he needs to stop feeding his plants so much bloom; looks like to much locking outcalicum, if I remember right to much phosphorus may lock out calicum,..... will have to double check....... my mind is going I tell you! To much stuff cramed in .... need more space in my brain!
