Iron deficiency?
labergstarted grow question 3y ago
This A.M I treated her with a cal-mag mix due to yellow leaves. Today the leaf showing symptoms "tacoed" a little bit and the tip curled upwards. Same symptom on a few other leaves but only on the tips. Iron deficiency perhaps? PH'd soil on 3 spots: 6.6, 6.18, 6.3. What to do????

If you're talking about the tips of the leaves being yellow, that's nute burn... and a very mild nute burn to boot... and nothing that calmag is going to do anything for... and nothing to worry about. The tacoing is different. Tacoing says your plant is too hot and is most likely caused by your lights being either too close or too intense... Raise your lights at least 3" or dim them somewhat... They should straighten out and be fine.
If you're worried about the new growth being a lighter green than the old growth - don't. That's perfectly normal and a healthy sign. They will darken as they age.
Good luck...

I saw the photo from day 45 and you did well to correct with calcium and magnesium; you avoided much more visible burns in my opinion. Those tips are due to this. I would wait a few more days to see the reaction after the cal mag and possibly correct them at the next watering.

The thing is with calcium/magnesium deficiency it's usually one or the other that's lacking and it's most likely an uptake issue caused by ph. So little of these nutrients are actually needed that I feel it's over used often and not properly.
Also results sometimes take weeks not days so give her time. I would do a little research on best ph for the medium I'm growing in for my plants to get the most nutrients possible.
Good luck.

Ya, see your problem right now you're seeing new growth which is a bit less green and lighter then old growth and thinking it's a definite and then trying to add something to the plant to fix it...Don't do that, you're over compensating for something that isn't even there...I'd give a mild flush and continue on as usually your tips are burnt because your over feeding...

Should I flush? (Overfeeding)I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.

Yellowing leaves and yesterday curl down leaves after wateringI'm growing in coco. Is 500ml/2 days too short watering? Last growth happened the same with lower leaves (yellowing). It was because of nitrogen deficiency. But EC go to much up if I add more fert. I'm at 5.7 pH and 1.2 EC, 25-26°C and 65% RH now. That's why I use worm humus.
