What is she telling me?
NugCalebstarted grow question 8 months ago
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?

I feel it could be more your lights. Your diary appears to say 150w in a 2x2 that You increased from 25% to 75%.
That’s a jump of 300%.
Maybe do that in flower but you are still in veg. If height gain is minimal and the leaves are curling at the edges then possibly the light is too intense. Try 24” away and 40% building up to 100% in flower with the light at 16-18”.
Get the free Photone app. It’s not bad. You may require a diffuser but that is just a price of normal notepad paper over the camera.
Ph should drift bit over a week not hours. Not sure on that one? Make sure meter is calibrated regularay

She's screaming, "AAAAAHHHHHHH!!!"
LOL.
The closest thing i see is a Mo deficiency on my leaf chart, but this would be rare. Whether in soil or using hydro nutes in a soilless/hydro context, should have plenty of trace elements.
6.1 is not a problem. It may need a slightly different ratio.. a few percent different here or there. e.g. may need less Ca at 6.1 than 5.6.
Looks like it started as interveinal damage and progressed to what we see here... only at bottom most leaf.
looks fairly unclear.. more info needed. some general ballpary ppms you want for your nutes 120-130N, 60P, 180+K, 100+Ca, 60-80Mg, 100+S
if near that.. it's not the formula at fault. that works well around 6pH and likely anything within a 2-3 tenths of that. If drastically off on any of that, adjust and see how it goes. This is a weak level of nutes. some plants may want more. drop the n near 100-110 after 2-3 weeks from flip/flower phase start.
pH swings can be the faultof the fertilizer. Good hydro fertilizer should be resistant to pH swings with proper buffering. This is the manufactuer's fault, if so.

Yellowing, curling tips?I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing?

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓

Weird Sugar Leaf BurningDoes anyone have an idea what happened to my leaves? They are trying up and burning for some reason but only 3 of the 7 that are in the tent. They are all clones from the same mother plant. At first I assumed it was too much light at 1200 ppfd but dropping it didn't help.

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000a year ago

Leaf tips browned. What nutrient problem is this?Leaf tips browned. And some signs of burn/discoloration at the leaf side edges.
Do you think it's general nutrients overdose? I didn't increase my PPM for the last two weeks, so I don't think it is a problem...
Or Potassium deficit? Or any other secondary nutrient deficit?

Leaf problemsMy leaves are getting yellow from the bottom, and some have burnt tips. It started when she is in flower.
I often feed Powder Feeding from Green House. PK+ (NPK: 0-30-27) and Hybrids (NPK: 15-7-22) the PH is 6.5
They say this strain wont need much nutrients but can handle more
