Second grow problems starting with leaves

[Newbee100]

This is my second grow... ya'll help tremendously when I almost fatally overwatered the first!

Situation:
Organic soil, ammended with 1/4 vermeculite, 1/2 perilite and 1/8 worm casings.
Grow tent
CFL lighting
78-82 degrees
38-42% humidity
2.5 gallon air pots
Planted sprouts 9/20
18/6 schedule
Lowryder Auto

First 3 of the 4 plants are HUGE for Lowryders. Did not see that on the first grow.

#1 - 28" tall
#2 - 33 3/4" tall
#3 - 22 3/4" tall
#4 - 35 1/2" tall

One of my plants looks okay, meaning dark green. All are in flower stage. But some of my leaves are yellowing. I weigh my plants everytime before watering, so I don't think tha tis the issue (but what do I know!). Gave them their first nutes 11/2. 1/8 tsp FF Grow Big, 1/8 tsp FF Tiger Bloom, 1 TBLS molassas as I started to see the yellowing at the bottom. This si what they look like today.

Should I be worried and if so, about what?

Well... You're using organic soil, I don't think Tiger Bloom is technically organic... I could be wrong there, I don't use pre bottled nutes. How much water did you mix all that in? I don't use veg and bloom nutes simultaneously, it's too much... I don't know what they say to do, but they're usually trying to sell more shit. Molasses is mostly to feed the microbiome, and if you don't have a strong one to eat up those sugars, that may have made the girls a little unhappy... or they could have just been very hungry... this is the first feed? Also you say 1/2 and 1/4 perlite and vermiculite... is that a percentage, a cup? If it's a percentage of the total pot, that's a lot. I personally don't have experience with autos, but those are my best guesses.

Dear NewBee,

The plants don’t look so bad. In fact, if it wasn’t for that pic with leaves darkened and shriveled at the tips I’d say things are progressing pretty well. 90% of what I see looks like natural senescence of the plant. Chlorotic leaves are scattered throughout therefore not clearly indicating a nutrient deficiency. Although the Mg and Mn might be on the low side. That could be a due to a low pH.

Zill.

 

[TSD]

Yeah they don't look horrible other than the shrivling... I'd just let them dry and give then some plain water next time.

 

[Newbee100]

Ugh! I have done something really wrong and my girls hate me! The last time I watered them was 11/2... they were not ready for water until today... on top of it all but 1 is struggling. Concerned I won't be able to get them over the finish line. They are on week 8 from planting now, so still have a bit of time to go. Sorry about the pic's not the best I have taken.

Stat's - All watered with plain water PH 6.26
#1 - run off 6.99
#2 - run off 6.65
#3 - run off 6.80
#4 - run off 6.96

I gave them all plan water and not a ton, just until run off. I don't know what the issue is, but using air pots is a new thing I am trying and don't think it is working well. Or at least I don't have it figured out yet. Any help or suggestions would be appriciated. The plant that I was originally concerned about now has yellow leaves sprinkled throughout it (pic #5 &6). I think adding nutes last time burned/ caused lockout on all the girls.

 

[Ganjadad]

Definitely looks like nute lock probably from the synthetic nutes being used in soil. Probably killed all the beneficial microbes in the soil. Also looks like root bound. Look into brewing teas, focus on getting the roots healthy and be patient

 

[Newbee100]

More help please.

I have been watering with PH under 6.5 but above 6.0. Today's water was PH 6.25. My run off on the first 2 came out PH 6.99 and 7.2. Teh girls are yellowing fast and I trying to save them. I did drop the PH on the last two to 5.58 in the hope that it would bring it down. Nope, PH run off was PH 6.81 and 7.04.

How or what do I do now.

Lowryder in soil, in airpots. Do I submerge the pots to try and flush them?

tthe lower leaves turning yellow. Is not necessarily a bad thing the lower leaves turn yellow typically because they’re getting less light and so the plant is instead of continuing to grow those leaves taking the nutrients from them and letting them fall off naturally it’s naturally defoliating itself

However through looking more closely your issue is a nitrogen deficiency please don’t do anything rash to your plant all it needs a little bit more nitrogen if you have a feed that you’re giving it give it a little bit more of the N

Why are you measuring run off in soil?
Especially pH???
You should be watering for minimum run off in organic.
You are washing away your nutes...
Your plants want magnesium and less run off.
Looks good .

New growers tend to analyze things too much and cause more problems then they fix. But hey. We have all been there haha.

 

[Cannagar]

It is worth noting that if you are measuring soil runoff it SHOULD be slightly acidic. Because soil is acidic. As your water moves through the medium it becomes more acidic tthe deeper it goes. If you are watering at too high of a base to get a runoff of 6.2 ish then that is your problem. Water normally at a PH of about 5.5 and you will be fine. (If it’s lockout).

 

[Newbee100]

Okay, wasn't expecting that question. Why am I testing run off in organic soil. Answer, because I thought I was supposed too. lol. Still way new to this. Here are my girls as sad as they are right now. We are at the end of week 8, week 9 starts 11/15. We have started to remove the yellow leave, just not sure how many to remove. They are starting to frost and the trich's are clear at this point.

 

[Cannagar]

At this stage I wouldn’t remove any of the leaves if they are yellowing they will fall off on their own. you can try wiggling them to see if they just fall off like that, otherwise this late I wouldn’t be defoliating

It doesn’t look that bad. Def a nitrogen deficiency or lock out. Just water regular and don’t add anything and just ride it out till the end

Thank you. I will water with 5.5ph. I have FF Grow Big 6-4-4 and FF Tiger Bloom 2-8-2. But the one and only time I used the nutes (on this grow) all my tips burned and turned down. Then they stopped drinking water for a bit. That is what started this thread. Is there another way to get nitrogen to them? One of my other problems may have been not getting them watered properly as I used Air Pots this time. Since I overwatered my first grow, I have been super careful this time. Well, at least I was trying to be.

No problem!

You may have fed too early and that’s why it burned or you may just have a soil that runs “hot” (high in nutes”

Since you are doing an organic grow you could try top dressing your soil with bat guano and that should solve the problem. Though be aware it will take some time for the nutrients to work their way into the soil.

Hello! Well, I thought things were going well. My plants stabilized and stopped looking half dead. So thank you for all the help.

My plants are now 14 weeks old. Still not seeing much amber, just a few here and there on the two smallest plants. Buds are growing.... but then that is my concern. They are starting to regenerate (that is the only way I know how to describe it) and are adding growth to the top of the buds.

They are all Lowryder auto's.
Getting ph 5.5 water with blackstrap
Air pots
Organic soil

Here are pictures. Any thoughts would be appreciated.

I tried to take close ups of the top buds and then the whole plant so hopefully you could see what I am talking about.

I don't really have experience with auto flowers so I can't really say about how they take nutes but I have used the full line of fox farm nutes for a long time altogether and in my experience if you follow the feed chart from seedling to the end I have had very few problems along the way.. I test the ec and ppm in my mixes and it's almost always right at what the chart says it should be.. the full line of soil nutes usually lower the pH quite a bit so I add pH up to get my plain water to around 9 before I add whatever nutrients it calls for the week.. I've always found it easier to lower the pH in the full mixture than raise it so I like to start a little high and level out right about the 5.9 pH area... Myself I water in with 5.8 pH water and then feed on top of the water.. roughly 32oz total liquid per feed to each 5 gallon pot every 3-4 days.. just what I do

The core issue is not enough light and poor ventilation. In order for a plant to process nutrients, it needs to be able to transpire water through transpiration. A gentle breeze on the canopy with strong light is needed for photosynthesis. The fan leaves in the photos are soft and plumped from excess water exposure.
