Pale green leaves with reddish tips?

MediciGradestarted grow question 3 years ago

Stress at the top of the canopy. Is this heat stress, light burn, or a combo? Something else? Temp in the tent hit 92.5 F at one point, but it's been high 80's in the tent and the leaf surface temp's have been low 80's. Light was 14 inches at one point but now 24 inches

Looking at your diary your growing in coco and been using very little nutrients. Also your ph is always at 6.5 which is at the high end for coco. If you get your ph closer to 6 and feed some blooming nutrients and cal mag she should bounce back. Try feeding a Ec of 1.2 or 1.4 and make sure you get run off. Go feed, let top inch dry, water, let top inch dry and repeat.

Hey mate, kinda looks like a potassium deficiency to me. But the lighter leaves is making it a little bit harder to diagnose. I think that she has used up her N which isnt a bad thing at this stage, thus making it a little harder to diagnose.

Leaves color changing in flower!!!!what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower? max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout? today i fed with 4.5 litres of compost tea + enzymes! pots are 14L.

She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.

Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

yellowing fan leaves after dry period Some of my fan leaves are turning yellow. I haven't defoliated much so I think it's good that she's sucking all water and nutrients out of old fan leaves. Anyway, since it's my first grow I would like your opinions. Are they yellowing because lack of h2o? See pic of dry, wilting

Seem to have a deficiency I am unfamiliar with. As you can see in picture 5 the leaf is changing colour to a light green, in the part of the leaf that is light green is very crispy and crumbles when you touch it.

The plant that stays in the center is having some problems. Sugar leaves are curling down and have brown-yellow spots, they also seem very dry (see the photos) . Only this plant is having those problems, what could it be?

In week 4 I planted the plants in a richly fertilized soil mixture. The leaves of the plants are now becoming more yellow. Do the plants suffer from a nutritional deficiency? What should I do? Adding organic fertilizer to the water tank could lead tot clogging of the tubes....

Can anyone identify what is happening with the lower shade leaves? A progressive, patchy paleness, from the spine of the leaf outwards and sides of leaves are cupping downwards. I gave cal/mag twice through the week along with bloom nutes. Is this a deficiency, small container..?
