Is this a CalMag deficiency?It started with White Widow a few days ago, showing signs of yellow leaf tips.
I'm quite sure I'm not overwatering.
Are they overfed (nutrient burn)?
I use plain water and applied Zamnesia Monster Bud Mix (Pellets) to the soil before the grow.
Scared for my first harvest.

Is it time to flush or wait a week?Hey what’s up grow gang, we’re approaching the final weeks of flowers, but I was curious as to if our grow is ready to be flushed, or if they possibly need another week of nutrients, and also the best flush technique for best results. Thank you for answering in advance!

Leaf damage/discolourationThe Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four

Yellowing leaves and nutrient lockout. How do I fix this? This has been a long time problem. Definitely overfed for the first 3 weeks of flower.Lemon Cherry Cookies locked out for weeks. She's yellowed up big time. Took in less than a quarter gallon water yesterday and a half gallon today. But then she had a higher EC and TDS before adding plain pHed water both days. After topping off it went back down. Check my diary.

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?Week 7

Feuilles jaunes en floraison : carence malgré BioBizz AllMixI have a pretty pronounced yellowing problem with the leaves of my plants after the end of the stretch. Almost all the plants are affected with big leaves that yellow quickly.
I'm growing in BioBizz Mix soil and avoiding nitrogen because I'm getting burns.
