started grow question 7y ago
Dear ganja gurus, please have a look at my diary Wk17 D119. I'm thinking nute lockout due to pH always below 5.8. But any other inputs is most welcome. Nute is 50 ppm epsom, 100ppm CaNO3, 100 ppm MKP, and topped with 7-5-16 A/B to 900ppm.

First and easiest way would be to push the PH up to 6.1 - 6.4. If it doesn´t get worse you did it right.

First, the lower leaves started turning yellow much quicker than usual during flower. I didn't change any Nute levels in my water because I wanted to see how things went. Then we had a few really hot days then this started happening to the leaves. more detail in week 17

Leaf Edges discoloured
I stopped nutrients a week ago. The soil is SoHum living soil though. Only gave CALMAG and BioBloom as i noticed a likely N deficiency. Today i noticed the tips are discoloured. Should i be concerned? Today they’ve been in flower for 7 weeks. Ill give them roughly 2 more weeks.

Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients.

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?

What could it be?
I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.
