Blotchy Leaves Problem - January 27 (Day 23)

GardenSchoolstarted grow question 4 years ago

In the last 24-hours all three of my plants have started to show signs of blotchy/irregular colored leaves. When I touch the blotches they are crisp to the touch. I have a really cheap pH meter, and I've been feeding at 6.5 pH. Is this a pH issue?

Hoi! Dit soort vlek heeft inderdaad te maken met ph-problemen. Ik zou voeden met een iets lagere ph. Controleer uw waarde in de grond. Hoe is de afvoer na uw watergift? Je lichtcyclus staat ook op 24/0, het zijn fotoperiode planten en dus moeten ze nog een lange tijd doorgaan. Verminder dit naar 20/4 of 18/6. Elke plant heeft nood aan duisternis om zich goed te kunnen ontwikkelen. 🌱

I just tested the pH of the soil and it was ~7.1-7.2. I followed your suggestion and flushed each plant with 4 liters of water pH'd to 6.0. Runoff now sitting at ~6.5-6.6 pH. Thanks again for your help!

I had a feeling. I will need to buy a new pH meter before my next feeding. I'll do a flush at a lower pH next watering and check the runoff. I haven't been watering enough to get an accurate runoff reading. I'll also turn my lights to a 20/4 schedule. Thanks for your input - it's really appreciated!

Any ideas on what's going on with NL-2? Fan leaves are discoloring, interesting pattern. From Websites, I'm thinking a potassium problem, but am not sure. And am not sure how to correct this close to harvest (3 weeks give or take). Thoughts?

I have some yellow spots as can be seen in Week 3 Day 20 pic. I am not really sure what it is or how to get rid of it. It appears to be on lower few nodes but not upper one so far. It is not affecting other plants in tent at this time.

should I be worried about those little white spots, do they indicate on some kind of deficiency or they will go away eventually by themselves? I mean there aren't much but still, got me little worried.

I'd like to know what happened to my plant but I'm unsure how to properly describe it. The photos in my diary should be able to make it more clean (W18). Maybe it was botrytis but I caught it on time? Or maybe something else? The trichomes got dark orange where all this happened!

There is a little bit of minor yellowing/browning in spots, on a few fan and sugar leafs. The plants otherwise seem healthy. Is this a normal part of this stage of flowering, or should I be concerned about nutrient issues? Thanks!
