Hey bro. Its cal mag def. But the tip burn, isn't tip burn. Its overwatering or some form of root rot.

Is it normal for new growth 10 days into flowering to be lightening in colour? I am new and noticing that it is fairly lighter than previous veg growth before as my nutrient needs and feed has changed. Just want to be safe! Thx 😄

Crispy bottom leaves (tip)
Need help!! Tip of bottom leaves are kinda drying out (crispy dry) and are a little bit curled down. Not sure if it’s improper ph, too much nutes or overwatering. Top leaves are fine, I dunno where I was lacking. Help a brother out, what do you guys think?

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Leaf Curling and yellowing on three week old plant, how to stop this gettign worse?
I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

Yellow leaves question.
Good morning growers, I have noticed some yellowing of the bottom flowers on my one of my plants. Everything else looks extremely vibrant and healthy. Does this look like a watering or nutrient issue? Or is it something I should not be too concerned with ? Thank you everyone :)
