Leaf discolouration. Nutrient deficiency?

TerraDoncstarted grow question 4 years ago

Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

How close is the light. Looks like the yellowing is start of light burn. But I believe you do have a nitrogen toxicity issue. Leaves won't recover. Feed a quarter or half dose nutrition. The plant has stored nitrogen. Still feed some the plant is using other parts of nutrition. Good luck and happy growing 🌲🌲🌲👊

Got the light to about 18 inches. Now moved up to 24. Turns out I had some problems with my soil - it went hydrophobic - hopefully this is sorted now though.

Is it normal for new growth 10 days into flowering to be lightening in colour? I am new and noticing that it is fairly lighter than previous veg growth before as my nutrient needs and feed has changed. Just want to be safe! Thx 😄

I don't have a PH meter, just some test strips. Can anyone recommend an inexpensive meter I can get in the UK? There's a bit of yellowing on some leaves (see my diary entry on week 8) Buds seem to be developing a bit slow Should I switch from 24 hr to 20/4 or 18/6 ?

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?

I have a deficiency. Can you please check out my pics and give your advice? I thinks its a Magnesium deficiency, am I correct? Increase CalMag? Flush with extra water? Any tips would be helpful.

This week my 4 week plant has been sickly and grew very little. The second leaves began to curl and when I touched them, they felt very brittle. Why? What I am trying is to increase the humidity, and moving the light further away. Little nitrogen has been given.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

So, my other plants have surpassed this OG, unfortunately, a week younger, too. I took pictures of the PH test Do you think that was the problem? (I personal so I don't water for the first 3 weeks, lol, otherwise the above happens.)

Hello guys! Overall the plant looks light green/yellowish and pretty small, with short internodes and bottom leaves with burnt and curled up tips. I give water every 3/4 days and commonly suggested fertilzers quantities. How can I let her recover and get bigger? Thanks :)

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Last compost tea was probably a bit too strong, causing clawing and droopiness these last few days. The following feeding was RO water only. I'm wondering whether there is some kind of nutrient lockout or N tox/def going on at the moment. Growth upward hasn't slowed down though.
