Yellowish color at the tips and wrinkles

GEESTGROWstarted grow question 4 hours ago

My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

Either the soil lacks nutrients (looking like nitrogen deficiency) or the pH is way off.

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 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.

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 :)

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 ?

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.

Noticed some brown tips showing up. . I've never fed at 100% full strength yet. Is it still to much or a deficiency you think?

Hey Guys, two or my plants seem to have a few yellow tips and some brown spots on the leaves. The problem is minor but I think it might be lacking Calcium? I think it needs some Cal Mag added to the next watering. Any advice would be appreciated. See pics. Thanks

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

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?

The last photos of this week show the burned tips on both floors. I think it can be an excess of potassium. Can anyone shed any light? Thank you
