Yes nutrient burn! Wash soil untill you have run-off. The feed you are giving has too much nitrogen, You are in flower, continue with a flowering feed high on potassium and phosphor, low in nitrogen.

Yellow tips
I noticed the tips of the leaves starting to yellow, mainly on the new growth.I haven’t noticed any other issues, being my first grow maybe I’m overlooking something. I raised my light up to 26-27 inches from 18 to see if that helps. Could this issue be from something else?

Slowed growth, yellowing top fan leaves
Any suggestions as to what my plant may be deficient in here? I have been feeding very minimally with less than the recommended amount every other week. Nutrients I am using are biobizz fish mix, bio bloom and top max with just some cheap compost soil.

Plants seem to be dying after repotting
Repotted all of my plants and they are very droopy and leaves are dry. I thought they were originally over watered but now I am not sure. They all seem to be dying. Any and all help is appreciated.

Deficiency or excess
Hello colleagues,please advise me, what could it be? the tips of the leaves are sometimes lighter, and the holey leaves? I didn't find any pests in the tent. I use the AH set. Once a week I only rinse with water with enzymes. Can you think of anything?

Should i worry?
Should i worry? Other growers said this is most likely a potassium shortage yesterday so I started feeding her a little more but if I compare todays pics to the pics of a few days ago I'm kinda shocked. You'll see which are the pics of today

Rate the Bud - 6 Week completed flowering
So this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning. On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

Early senescence on Runtz?
Based on your experience growing Runtz and/or the pictures posted below, what week would you say we're in? I'm asking cause leaves are yellowing and unless I overwatered them it looks like a very early senescence, no? I'm a newbie so there are obvious things I don't see :) Cheers
