Carences ?

Celestostarted grow question 3 years ago

Les veines des feuilles des Txerri Bilbo Haze deviennent légèrement bleues, est-ce une carence de phosphore ? Les feuilles de la Master Kush s'éclaircissent sur les bords, est-ce bien un manque d'oligo-éléments ?

Could be a copper deficiency. Very slim chance it's Tobacco Mosaic Virus

Yellowish color on most of the leaves and the condition did not change after watering. I suspect it's nitrogen deficiency or some pH problems. The plant is in pre-flowering, with sex being revealed. Will go into flowering soon. I watered it with 1.5l Any thoughts?

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 :)

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.)

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?

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 ?

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 😄

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.

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

On two of the oldest plants their first true leaves are turning a yellowish color and every cotyledon appears to be yellow now. Is this due to watering or too much light or something?
