What Nute Deficiency Is This

Hi folks, this is a soil grow and the plant is 4 weeks old. Grown indoors, watering every day (have been watering twice per day).

I first water when I move them from the veg tent to the flowering tent (I have plants in flower so when the flowering lights come on in the morning rather than running two sets of lights simultaneously.

I move the plants in veg into the flowering tent under a duel spectrum 400w HPS) and turn off the lights in the vegging area.

I have noticed this on the edge of one leaf.

Is this a deficiency and if so what do you suspect as the cause/remedy?

Thank you.

do you pH and what all do you feed?

to me it looks over feeding

Don't water every day. You want to let the soil dry out. The finger test is when you stick your finger in the dirt. You don't want to water until the top couple inches are dry. So start fingering your dirt. hahah

looks like mild nute burn. GL

[FONT=&quot]Yeah, my soil PH is at a steady 7, never seems to move somehow.

Well for this grow I am feeding (everything is at half or quarter recommended dosages) I feed them a tea of molasses, Blood and Bone Meal, Bat Guano and Poultry pellets once per week and the rest of the time distilled water.

The plant you see is 4 weeks old, still in veg and get water twice per although been cutting down to once a day recently.

So over watering is a distinct possibility. [/FONT]

Slight nute burn is a definite probability....
Bone and Blood meal on top of Guano and Poultry pellets. Way to much food for such a young plant. Poultry pellets alone should be more than enough.

[FONT=&amp]I potted these up to the big pots pretty quick so was concerned about the roots being somewhere mid-pot and I didn't want the roots to dry.

But I've just checked a taller plant same age and a root strand has come through the bottom, so the roots of this plant shouldn't be far behind.

Gonna ease up on the watering, for sure.

Yeah, I’ve got a moisture tester for those little jobs.

I’ll wait till it starts approaching dry before I feed these now.

They are filling up their pots nicely.

my vote will lean towards nute burn.

My mother plants had the same issue at 17 days:

This is my Cinderella 99 mother plant and after some research I came up with that it could be moisture/heat stress. I had a few issues for a couple days but think I got it figured out. Also, I water my plants every 3-4 or even 5 days, no nutrients just PH'ed water. What is your plants environment like, It just started getting sickening hot where I'm at how's the temp/RH where you are?

Very interesting.

My vegging area is kinda new and I don’t have a fan in there yet, it gets up into the 80's df and low humidity 30's (the plants are in there overnight).

They are also on a 22 hr lights on schedule, so these factors adding up are starting to create a picture.

The more recent pic I showed was from the end of last week, not sure they had had there first of the above recipe yet and I just noticed she had it back then too.

So while it's possibly a slight nute burn, it could also be over watering (which I think is a strong suspect) or mild heat stress (also very possible).

You gotta let them do their thing man, don't coddle them, patience patience patience...I know it's exciting, but you gotta find something else to do instead of watering them all the time

I thought it was Cal def, but not sure.

I thought it was magnesium and then potassium.

trust me, if it was from overwatering, you would know. however it's not the case. could possibly be cal, but if so, you would have seen a mag issue follow right behind it. i strongly believe it's from nute burn.

a friend of mine had a similar problem, we looked it up on the sick plants chart and it confirmed it was a cal def, he waters his plants with tap water which has calcuim. upon further reading it turned out that too much potash will cause a cal lock up, which made sense, since he gave his plants a lot of 0-0-50.

good luck

That's a good point.

Yeah, I'm looking into cal, potash, mag.

Thanks.

Any updates on the results? After squaring my Veg room away (brand new room, first time grower) with its environment issues (heat) all the new growth looks really really good. Was it Cal or Mag in your case? You're plants looked a lot like mine did so I thought with the change in outdoor climate (summer's here) it might be that Good Luck!

The craziness never fails...

You admit to watering every day, so, roots are closer to surface than if you’d have let them dry out a bit more… Plant looked dry to you, but you never let it…

So plant had shallow depth roots. Then [burnt tips] I think the plants were over heated, shallow rooted plant, took brunt of problem… [This has happened to me before]

If the top of your plants tips start to also turn brown, you have major problem…

Heat plus shallow roots show on plants as burnt tips, first… on just a few, then spreads…

Keep your plants cooler, what is temp at top of plants? What is temp of soil?

Heat stress will also lead to what looks like ’classic’ PH issues, and N deficient, so if the plant looks worse with everything you try to do, your plant is doomed….

I’ve been asked:

“If it’s heat stress, then why did it effect only one or two of my plants ?”

Only those plants had a too shallow root system…

Change your water habits, no matter how hot you think your plants water needs are…

You can bring them back from heat stress, if you are lucky… otherwise…

Good Luck…
