Indoor Excess or deficient?

[Waira]

last time I'm going to do this Tree... clean up the mess and prevent you from causing actual harm,...

I’d definitely say excess nitrogen and burn... a pH of 6.2 is NOT “horrible” but I’d definitely try getting it down below 6.0, to 5.8 ish...

WTF are you talking about here? This is soil, true soil, not soilless.... optimal pH is around 6.5-6.2... 6.0 is getting shaky, and 5.8 is going to start P lockout,... and worse, since nearly always when pH trouble comes, it's going acidic, not alkaline so riding the borderline for pH give no wiggle room for error or normal fluctuation... compounding this is OF soil's notorious reputation for being too acidic, undercooked crap... Never advise a pH change until you KNOW what the pH is in the pot! Try reading a nutrient availability chart sometime,....

I’d definitely say excess nitrogen and burn....
No seed.. is too young to feed!
Feed the seed!... it will grow with a “head start” for sure!
.

Here you are telling him to feed right after you diagnose nute burn?? Did you not read the form? BTW, dark color can be a normal expression of a given strain or pheno', and the camera


/lighting is a significant factor as well,.. with no nutes going in, this isn't any sort of N-toxicity.... Only thing you got right was the higher pH eventually causing lockout of several micronutes....

. then a friend suggested Jack’s... hydroponic fertilizer, it’s good for DWC, soil, coco... it’s so easy to understand,

Aaaand here you are spamming Jacks again,...and again... very suspect dude.....

I’m speaking out of turn I’m sure... but I agree with you on the different opinions etc. on other people’s experiences with “issues”.

yes you are indeed... right out of your ass! There is no red tape here, just the need for reasonably complete info to reach a quality, carefully considered diagnosis, which error filled "opinion" is not... if you don't like how things are run here, then bugger off! This is the most time consuming, difficult task there is on this site, and BTW fucking way, it's all volunteer run, so at times when there is a crush of incoming people, it will take some time to work though things... better to have delayed advise than the fast food crap you keep serving up here! Worse, you offered no fix to anything, anyway....
... Again, final warning, stay out of this section, or your stay here at AFN will be very short...

Here we go. Thank you.


Problem: leaf discoloration

Medium/grow method: foxfarm ocean forest

Feed: none - plants were too you I think to start feeding. Now finishing up week 3 from seedlings.

water source: tap, phed 6.2

Strain/age: various, auto blue berry, auto purple kush, magnum automatic, auto northern lights, CBD jack herer, all in week 3.

light used: meihzi 300w cob + 600w purple led. Drawing roughly 280w at the wall total

Climate: 48% RH, 84F,

Thank you very much

Karl, pardon the drama mate, but it HAD to be done,.... As mentioned, OF is horrid soil often badly off pH- acidic.... poorly cooked too, part of why it's pH is so often suspect... with no nutes going in, nute burn is out which is why we ask for so much info... A lot of symptoms can have different causes, or be combo's of things that muddy the diagnostic waters! Worse, that soil in anything but complete for the full nutritional profile the needs to thrive, not just survive,... the catch is, if you need to feed to get some balance in there, you have to be careful about the pH in-pot, not just going in, and the relative strength of your dosage... Symptoms showing mimic nute burn, but also a pH issue and poor uptake... sometimes the nute's are there, but not available, not in absorbable chemical form,.... So, if it's just those 1-2 lower leaves, the situation isn't bad, new growth looks OK,... the tip and margin necrosis, interveinal yellowing all hint at a poor nutrient balance and off pH... We need to figure out what the ph is that pot before feeding because that can make matters worse... feeds are usually acidic as well....
I gather you don't have a soil pH probe? The last resort is a run-off check; this is not a reliable measure of actual in-pot pH, but if done right, the reading you get can at least indicate that there's a problem there, and a fix can be offered! Do you have a pH meter, calibrated and in good working order? Can you get hold of some distilled or RO water? What size pot is this? You'll need to pour through enough unadjusted, low ppm water to get at least 30% run-off, and collect pH sample at the end, not beginning... this is like a cone type coffee filter, everything is concentrating as it goes down through the soil, so what comes out first is overly rich relative to what in the pot overall... If you go to the colored section above this one, there's a "improved" run-off pH method and calculation method shown, .. this will give you the gist of all this, and if you want to do it that way to get a better reading, you can,... the quickie method I mentioned may help at least show if the in-pot pH is really off, and we can work from there,... if it's bad enough, a flush may be called for anyway!

Hey guys. Thanks for the input. I myself tent to maybe diagnose things I'd I feel I might have a clue, but it's challenging considering the various variables.

Anyways, I appreciate the feedback.

I will flush the pots. I think that's my best option to get things more neutral. So I flush with regular, phd water?

I will try to measure the runoff,I don't have a digital meter and use an aquarium solution which I find works very well from experience in my first grow.
