I’m using standard tap water but adding PH. It’s only happening to a few plants and there are 15 in total we have had hot weather in the UK this week so it’s been hard to keep the temperature down. I thought that may have something to do with it?

Are you using R/O water when you water?

Starting to fade? Or nutrient deficiency?
One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.
Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing. I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"

Struggling with deficiencies (nutrient lockout?)
Hello everyone, I need your help. I've been growing 2 Green Gelato Auto from RQS but I've had some deficiencies for a while now. It's my second grow and it's the first time that I adjust the pH. They are in soil and I'm feeding them with Biobizz liquid nutes at a pH between 6-7.

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Curled leaves and brown spots
Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.

Classic N toxicity (:
Heyho :) since she has progressing leaf tip burn and curled tips which I'd almost certainly say is a nitrogen toxicity, would you recommend going down to 50% general strength or maybe leave out the grow supplement at all and just feed Bloom? Cheers guys :)

Calcium deficiency?
I'm not so sure if it's calcium deficiency, what do you think? Watering 100ml of water minimum. Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free. Should I water her more and add more calmag or is this a different deficiency?
