Brown spots on leaves! To Flush or not to Flush? That is the Question.
ColonelForbin1990started grow question 2 years ago
Hello,
Seeing lots of brown spots developing around middle tier leaves. Reddit is telling me I should flush with 15 gallons of water to get rid of salts around the roots. That seems extreme but if that’s the cure I’d like to know more and can I use my tap water (7.1pH 133ppm)?

Looks like they need calcium. I would up the bloom nutes and feed some cal mag. Best of luck the rest of the way.

PH should be around 6.4— that high you can’t absorb all the nutrients—- hence what you are seeing. I never flush, but you can….
Do a couple of water feeds 6.4, a tea feed 6.4, and go back to nutrients at 6.4

Really! a flush?!
To flush what? your feeding is so low, and it is the first week you are giving some.
Your fox farm soil is depleted, and you auto is at peek demand for nutrients, you need to up your feeding.

Purple leaves getting worse!?So I started getting light purple/yellowing last week, after my last grow question, I landed on potassium deficiency. I gave a healthy dose (2 tbsp in a half gallon of spring water) of Fox farms big bloom (0-.05-.07), within the last 48 hrs and the purple looks worse? Any ideas?

Нлвые проблемы с переводом на цветениеЗаметил побеление на кончиках листьев. В основном на нижних, но есть и на паре верхних. Не могу определить, то ли перекормил, добавив Bloom booster, то ли дефицит калия и кальция с переводом на цветение, буду рад любым советам и адекватной критикеWeek 8

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Yellow leaves near the harvestThis would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest

Calmag deficiency or Nutrient lockout caused by Pk excess ?Flo+44. Probably I didn't remove Pk fast enough (left it for more than 19 days, should have left it for 15). So I reduced the nutes from 1.15 to 0.70 now, hoping to avoid the lockout... Thx !
