Deficiency Problems
Gamabuntastarted grow question 5 years ago
I don't know why they suddenly show so much deficiency.
Do I need to readjust the PH level or add more nutrients
Could it be because of the stronger lamp?
I switched from GC 4 to GC 9 from Greenception about 1 week ago. Which corresponds to a change from 250w to 400w NDL.

Hey man, I'm using biobizz too. I think at this stage all your nutrients should be at least 1ml/2ml higher in dose. And you need to try watering at ph6. 5. Adding calmag won't hurt either. Some levees will begin to yellow but you're a little early I think.

Get the calmag in there. led rinses the hell out of the Mg alongside coco too. Add a dose in with their feed at ph 5.9.

Check the runoff PH first and recheck the manufacturer guidelines for lamp distance. I wouldn’t go heavier on Nutes without knowing what the problem is

I'm not an expert but:
Which week of bloom are you in? Are they dropping naturally to show you it's nearly harvest time? Your photo says week 6 of bloom? The leaves and roots will be at least partially cannibalized around now. 8 weeks is usually harvest time.
I didn't realise this when starting out so thought they were under-nuted.
Alternatively, you've upped their light so there's more photosynthesis and I'd adjust the nutes to reflect that they're at the end of bloom and are using up lots of potassium. If you're starving them for the last two weeks then their fan leaves etc will go yellow and drop. It looks scary.
Checking the PH is never s bad option in case of nutrient lockout.
As I said I'm no expert, just past beginner, so maybe confirm these thoughts with someone else.

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

Runoffs are significantly below inputs-Do I have a problem?Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?

Autos reacting to All-Mix: Slight nitrogen overload?Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks
