Deficiency discoloration?
GrowBrosIncstarted grow question 6y ago
I noticed some light de-coloration on the tips of one of the tops. Is it just because its new growth or do I have a deficiency? Thanks for the feed back.

Looks like the start of a cal mag deficiency or a ph problem makes sure those 2 are in line and you should be fine.

That’s not normal, could be magnesium deficiency but I can’t be sure. How much Mg are you giving to the plant? It should be between 50 and 80 ppm

Puntas de las hojas amarillas, otras en garra y otras quemadas, que puede ser? Las plantas están en la 5ta semanita de crecimiento y ya pase a 12/12!!Yesterday I watered my plants with Grotek fertilizers, putting exactly what the growth chart shows, and today my plants woke up like this. I don't know if it's because of the heater in the middle or the monster grow that adds too much nitrogen. What could they have??

Brown/rust spots and yellow leaves at the bottomPlant in late veg (soil) is showing spreading brown/rust spots on upper leaves and rapid yellowing on lower leaves. Frist only at one plant and now at the others too. I suspect a pH-induced Cal-Mag lockout. But I always check pH to be around 6,5. What should I do?

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures).

Leaves with yellow spotsWe have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).

orange sherbet crispy leaves. Close to harvestFastbuds Orange sherbet first grow. I already harvested this plant but I’m curious what the issue was. The leaves were yellow and crispy to the touch. Other leaves looked fine. 2.5oz harvest but it dried really fast(7 days) and now smokes harsh. Don’t want to repeat this mistake.

On Week 11 Day 74, I've been noticing the leaves turning yellow. I'm assuming because we're getting close to harvest, but after reading more about nutrient deficiencies I'm wondering if I should be doing something about it. I started flushing a 1.5 weeks ago.
