Weak yellow leaves with red Stems
Weak yellow leaves on the bottom with red stems. I use 1/3 tap water, 2/3 filtered water for its pH levels. Could that be my issue? I feed twice a week Fox Farm Big bloom 2ml/l, Grow Big 2ml/l and Cal/Mag 0.5/l. Cal/Mag with every watering to make up for the soft water.

Only Fan leaves starting to turn yellow?
Why are only the Fan leaves starting to turn yellow from the outside inward? All other leaves are okay and green. Blueberry Auto 10 weeks old, organic soil grow. Should I remove? Comming up on the flushing period soon.

Droopy leaves, weird spots.
Does anyone know what's wrong with that bottom left plant? Those spots appeared pretty soon after I cleaned those filters. I'm thinking that it's a stress caused by that cleanse, no chemicals or such were used, but some roots were torn in the process. Deficiency? Disease?

What’s going on here?
What’s going on with this one bud on Cotton Candy Kush plant? It has some leaves dying. No damage to the stem & only bud looking this way. It’s on day 50 of flower and has been getting lighter leaves overall this week. It’s supposed to flower 50-60 days, according to the breeder.

I don't have a PH meter, just some test strips. Can anyone recommend an inexpensive meter I can get in the UK? There's a bit of yellowing on some leaves (see my diary entry on week 8) Buds seem to be developing a bit slow Should I switch from 24 hr to 20/4 or 18/6 ?
