hey there it's potassium deficiency, you can see because the veins of the leaves stay green.

Nutrient problem??? Excess or deficiency?
What do you think is the leaf issue? Open to second opinions. Most everything stayed the same, except: > increased water: 2L to 3L per 7 gal of soil > introduced a bloom booster > increased volume of worm castings, molasses, mycrobes and ethylene to the tea

problems with low leaves
in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Nutrient burn?
The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?

Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!

Cant find pH section. Leaf edges are burnt. Working on a student budget, had to postpone buying pH meter. Local tabwater is 7,03 - 7,74 according to internet. Ill be adjusting pH starting Thursday. Can I go to 6.0 straight away or should I go down in steps of say 0.2 to adapt
