Phosphorus def in veg?
Fordsiestarted grow question 3 years ago
Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

Hey
So I would definitely lean towards a phosphorus deficiency....but it can sometimes be connected with calcium too. Personally when i started regularly using a calmag supplement my plants were much happier.
Your plants don't use much phosphorus in this early stage and if you're giving a regular regimen of the flora this shouldn't be happening. Double check the outgoing runoff ph and if its coming out in the right range then I would highly suggest recalibration of your ph pen. They usually need it done every so often depending on how often its used. I usually recalibrate at least once a month because i had a ph pen go off and it caused total havoc on all my leaves.
Happy growing.✌️

@experimentgreen, I took a pH reading of tap water, then recalibrated my pH meter, and rechecked tap water...Holy Crap, you are right, it was totally off, by like a lot! What a freaking rookie mistake! I have been feeding these girls with a nute solution that was way to acidic. Damn it! They look so sad right now. I’m going to flush them and refeed with cal-mag at proper pH. I can’t believe I made this mistake, what an a**! Thank you for your feed back and recommendation, so very much appreciated. I’ll post progress in next update, fingers crossed things will normalize. Can’t say that I won’t still be embarrassed that this was due to user error and completely avoidable.

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Concern about VPD, stretch, twisting leaves ... or is it OK?This Gorilla Zkittles seems to be stretching awfully much. Also, of more concern, the small leaves are twisting, as if too hot/dry. 78F, light is about 14" up, RH% setpoint 56%, leaf temps seems to max out at 76.5F. Should I worry? Or what? Thanks! VPD is 1.2-1.6 depending.

Dark leaves and short/compact plant18 days from seedling. Dark and a bit rumpled/twisted leaves. Branches are coming out but they don't have much space to breathe from the big leaves. Started topping with some chicken manure pellets, too much nitrogen? Also, the 36W LED lamp is only 20 cm away.

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

I added mycorrhiza to the coco coir from a local store. It turned out that there is slow release fertilizers in it. Was not indicated on the packaging.Please Help!
First time after watering with 5.7pH 400ppm drainage water was 6.7pH and 800ppm. I flushed her to 400ppm.
Yesterday was the second watering (450ppm, 5.7pH) and drain was 700ppm 6.7pH. I flushed her to 460ppm (1.5l of water), but pH still 6.6
How to fix it?
