Could be the light but I think its nutrient burn. If your using this https://www.plagron.com/en/products/growmix
It says it has an ec of 1.5 and then your adding nutrients on top of that. Way to much for an auto flower.
Stick to straight water for at least 2 weeks. You will only need to add nutrients when the soil has been depleted.
As for your light I would stick with the manufactures recommendation. go 45cm at 100%.
That bug is an aphid NOT GOOD. They can quickly infest a crop. I would get some organic soap insect spray and spray your plant before it flowers.

You did it
Moved to lamp up to 60cm above the plant and lowered the amount only watered the plant with 1ml Terra Grow without the Power Roots and Pure Zym.
Good luck

Oh for goodness sake, please start a diary! There are so many things this could be the result of and we need more information in order to help you! What nutes are you using? How old is she? This looks like it could be a zinc deficiency ... how are you measuring the PH? The problem is we don't have a diary and, tbh, even if you give answers to our questions HERE, we probably aren't going to come back to see if you've answered them... the diary is crucial! Start a diary, join the community - we really DO want to help!

I am using soil, Plagron Growmix with perlite.
PH at water/nutrients is at 6.4 PH
Its an Autoflower Afghan Mass XXL.
The light was about 35/40 cm of the plant, I lifted it back up to 60cm now.

Chow_13answered grow question 3 years ago
what light are you using and how far is it from the canopy. Are you using coco or soil ?What is the ph of the water/nutrients when you feed/water. 5 ml/l is recommended feed so at 1.5 its probably not nutrient issue. is this an auto flower or photo.
I would guess light burn. If not then lack of food or ph out of range

Clawing on Lemon Cherry Cookies Fast Buds Biobizz light mixDoes anyone know what this Lemon Cherry Cookie might have? I assume it's too much nutritiens because of the "clawing" of some leafs, but it also has brighter green newer leafs, it's in a biobizz light mix, so I thought she can get the dosage by biobizz plan from week 2-1/2 onLeaves.

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. Thanks4 months ago

Leaf-tips going droopy modeAfter my second to last watering the tips of all of the leaves started to droop a bit. I though it was connected to the night-cycle of my light, but it continues to worsen every day. However I only watered after the soil was dry too the touch? Is it really overwatering or else?Leaves.

Should I do full flush til runoff is 300ppm?So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it?
Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow.
Today 3L water, pH:6.2,
runoff:0.6l, ppm:1450, Ph6.0Leaves. Color - Yellow

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?Leaves. Curl down

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F).

Lower leaves too pale or yellowing?I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant.
Is this a nutrient/light/watering/lst stress problem if at all?
