Yellowing
Medesstarted grow question 2 years ago
First timer here,past week i have had issues with lower leaves yellowing and getting brown spots and falling off.
Went from veg state to bloom, the light scheduling got messed up for a week 15/9. I do not know if lockout because of ph imbalance. Light is 12/12 now

I see you're using BIobizz, if it's a light mix, that's your issue. I've done the same on my Ztrawberry plant. And it needs PH'ed to 6. It helps the plant break down the feed. Also the spots. You need cal powder from GHF. As they suggest that's needed. Especially if your tap is less than 200ppm cal powder will be needed.
They do say, if you use. Its recommended you start of with a soil that has nutes in it. As biobizz light mix consists of 70% coco/perlite and the rest, (therefore, a lower PH is needed). As there's more than enough nutrients in biobloom for 8-10 weeks. So, its not lack of N. You're right, it'll be more of a PH issue.

Hi Gottagrowsometime
Thx, yes I checked up the ph and it was around 7. Flushed with 10L water and waiting to see how it will be by the next days. Do you suggest giving them biobloom again in a week? Slowly, i only give them 11grams every week so that i have control over atleast that.

Forgot to alter pHHi I forgot to alter the pH. I already have some issues (I think pH? Check picture). What’s worse, overwatering or too high pH? Do I need to flush ASAP or wait till next watering cycle? The pH of the water I used is 7,7 and I have organic potting soil so is it a big deal or not?

Leaf burnt edgesOne leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

Should I remove foliage affected by deficiency, or just let it ride?Autoflower started showing sign of deficiency at week 8. Assuming CalMag, as I filter my water and affected area is new growth at top of plant (see pic).
1) Can someone confirm CalMag deficiency or something else?
2) Should I remove affected leaves or leave them be?
Thanks
