Early Deficiencies?

[Carbon]

You are correct i do indeed have very hard water and it was i who contacted you about it before
Lights are CFL bulbs, 9x 30w which are 2000 lumens each. This is a picture of inside my tent to give you an idea of how many lights directly on the plants and at what distance. Lights are on 20/4 off time being during the day so as its not to cold.
Temps are 76-80f with lights on and 68-70 with lights off, I have two pc fans inside the tent for air movement one 140mm 92cfm and one 120mm unknown cfm but very strong little fan.
I have a cold air intake sucking air from my window onto the floor of the tent of which im not sure could be having an effect.

I am running plagron light mix but have only just started to use nutes as i didnt have any before hand. So far both have had a half dose of greenfuse grow stim and a half dose of ionic grow nutes (not in the same feeding about 5 days apart)

As for the blemishes i did think they were my mistake while watering and getting nutes on them but had spotted some higher up the plant, This could well still be my mistake though.

Hears some pictures of full plants in which you can see lower fan leaves :thumbs:

Ps. the washed out look has been present in both my jacks from seed (smaller smaller of the two)

After seeing those pictures, I don't know that I would even flush. I would just do quarter strength next time. Especially if this was their first experience with nutes, they were just reacting...i don't think you are having much of a problem at all. She's just a bit sensitive. And the jack I think is named that because its jacked up. I wish I could tell you what to do, but I would be guessing myself.
They look great! And I really am impressed with that jack! I didn't think it was gonna go anywhere but she's taking off!

Hey carbon! This is one of those take a deep breath and a step back moments. First of all, don't panic! Doing anything while panicking means you will probably overlook something and do something else wrong and make it worse.
So, first, don't worry so much about random marks or brown spots on leaves unless you start to notice a pattern. Dripping some nutes on leaves can cause all sorts of marks and discolorations.
What you have going on here is a case of nute burn. I'm almost completely positive.
The curly leaves are a sign of too much nitrogen usually (though sometimes random) and the tips are burned from too many nutes.
The paler top is totally normal. Often when they kick into flower you get a much more lime green tint to the top growth.
Those burned tips are nothing to worry about at this point but are a great indicator.
What I would do is flush with plain 6.5 pH water...3 times the normal volume of the pot.
Wait 24 hours
Feed VERY LIGHTLY...like only 25 % of what you last fed...so if you were already only feeding 1/4 strength nutes...feed 1/4 of that 1/4... Make sense?
That's one of the big reasons I feed with organics. It's very hard to over-feed with the organics. Autos tend to be very sensitive to chemical nutes, and it takes people some time to dial in to what the plant likes, and then each plant is different.

You caught it early! She will be totally fine. Can you post a full plant shot from the top and side in normal room light...not the bright lights of the tent. It would be great to see that before you dive in, just to make sure. Sometimes the close ups can be hard to tell with.

Thanks dude! im trying my very best to stay calm a get a 100% diagnosis before taking any actions.
Some of the random spots have been present for a while now and have not spread at all so i had not been to worried.
Once the plant come into flower is 100% when the tips started to show yellowing so what your saying makes sense :thumbs:
As for nute burn so far all these girls have had is 0.5 ml of greenfuse organic grow stim and 4ml on ionic organic grow nutes and these were both in separate feedings.

These are the pictures you requested..

Im very confident ive caught this early enough that is shouldn't cause long term issues like you say, i just want to know for sure whats up before i put anything in there

Ps. you didn't sound mean at all! exactly what i wanted to hear if im honest :thumbs:

Just an example for you...
This is a pic I just took of a lower leaf on my auto pounder. By the looks of it, I have nitrogen and phosphorus deficiencies and maybe even a little cal/mag problem...
But I really don't. It's just an old leaf and they'll do that as the plant starts making flowers. My guess it it decides that they are so far away from the light and under the plant it just doesn't really need them and it eats them up! I just pull them once they are really dead.

That being said, if more than just one or two o ld leaves are doing things like this, it's a problem. I just wanted to show you that even a totally happy plant can have a sad leaf!

If i'm honest i don't feel iv'e been paying enough attention to the leaves now but im not sure how long it would take for the problems to show.
Is the ripped almost eaten looking leaf also nute burn? seems to be an extreme reaction in a short space of time 2-3 days however i dont know! the joys of being a noob! lol
I agree the jack is just totally jacked up, i kinda just leave her to do her thing and she just get watered when the cream does Im also shocked by her growth though, i cant even see the stem!

That's just some damage from something. Who knows what. I'd ignore it unless it starts to spread.

Thanks for that pic darwin! i hadn't posted one myself as i figured thats what was going on but her first leaves are yellowing and look to be dying (the single blade leaves) :thumbs:

Ok cool, thinking about it that could totally be my temp probe but it still wouldn't explain it on the jack :S

My ..

Some how the Jack received too much Nitrogen? Not sure how, I can't find anything about that Greenfuse Growth Stimulator.. it appears to be a knock-off of superthrive that's "100% organic".. either way, that Jack looks overfertilized.. the leaves are tacoing and are a very very rich green. The instructions say not to use more than a "couple of drops per gallon" (I'd never use a fertilizer that gave an instruction like that, IMO).. how much of it are you using? Superthrive for example is only fed for about two weeks typically then discontinued.. As well, she looks overwatered. The textured look on the leaves and how they're sagging leads me to this.. make sure you're letting her dry out 100%..

The Cream Mandarin looks great brother, she looks thirsty though.. the leaves are tacoing a bit but they're nowhere near as waxy as the Jack.. do both sides of the Jack look the same or just the sides that are towards the light bulbs? Do you rotate your plants? Do you have anything in the cab blowing air on them lightly? One little drop (think half of a rain drop size drop) of nutrient water (especially a nutrient as potent as one that says use so little) can cause a blemish if the water is left there and light hits it for a period of time.

My suggestion is to get some air circulating in that tent, blowing lightly, very lightly on the plants.. Next, how cold is the cold air intake? The temperature of your root zones is very important, if anything that cool air should be propped up to blow over the tops of the plants. Not at the pots. The pots won't dry anywhere near as fast with cold air blowing on them. The roots won't take up nutrients as efficiently either.

Discontinue that Greenfuse mojo and start working towards your grow nutes.. 1/2str, 1/2str, you see no burn, no issues? 3/4 str, 3/4str.. no burn, no issues? move on to full strength.. to get to your desired nutrient level will take about a week and a half to two weeks. You've already finished up one of the 1/2 str grows.. Your CFLs are at a good height man. I take it when you water one plant, you water the other? Not all plants will take up water at the same speed!

Im not sure myself how the jack would have gotten to much Nitrogen because shes had the exact same treatment as the cream. This Is the greenfuse and like i say both the jack and cream have only had 0.5 ml to 1 liter one time (instructions say to use 1ml per liter)
She was over watered for the first week or so of her life but that lesson was well learnt and now she gets bone dry before watering. The whole of the jack looks the same however its only the top of the cream showing signs of any issues. I do rotate my plants daily :thumbs:

I have two pc fans as mention in previous post and all plants have nice light air movement around them. I'm now almost sure the blemish's are indeed my mistake with nute water so thats a weight of my shoulders As for the cold air intake i have no idea what i was thinking just exactly, i should have never put it anywhere near my roots and i'm about to move it so its just at the intake of my tent.

Ill not be using anymore greenfuse at all from now on, however a question i have is how long before i switch to bloom nutes on the cream? I'll be using Oldtimers Bloom :thumbs:
