Calmag deficiency?
Robertsanswered grow question 4y ago
Yes but a soil ph check would be my first thing to look at. Make sure you are in range. Nitrogen level is a little heavy.

Yellow leaves at the end of flowering, should I worry?I can use some help on this one. I am pretty new. The variety is called Hawaiian Staycation. It has done well and we are in the last week or so of flowering. It got a bit dry in the tent and the leaves really yellowed. I plan on harvesting next week, should I be concerned?

What's my leaf saying?I just moved my plants into a tent and watered, with nutrition (as above)... I saw two leaves that showed up with a rusty, burn to it... A few thoughts: 1- pH... It's been at about 6.5/7, but leaned a little high this reading. 2- Light burn... 3. Nutrition difficiency?

DeficiencySpotted a deficiency on my AK 420
Checked on growweedeasy charts and Imo it's a cal/mag deficiency.
I meticulously check Ph and runoff and she had the same treatment as my royal dwarf.
Probably more hungry than the others.
Just wanted to make sure, cal/mag deficiency right?

Leaf DiagnosisCould someone help diagnose this leaf problem. It's less than 2 days old. Aañnnnnd, 2 days ago I accidentally set the ppm to 1700? I've since dumped the solution and got it back down to around 700 ppm. I'm hoping someone give me some triage pointers. Should I trim those leaves?

Light colored sugar leavesI'm at the end of week 6 and the plant is looking healthy overall but there are some bud sites that have some sugar leaves that are developing with a lime green color. Im thinking I might have been a little high on the ec so I backed off a couple days ago. Thoughts?
