Looks like a calcium deficiency. With being in flowering I would check your substrate ph first. Flowering tends to draw a lot of phosphorus which if more is not added your ph will climb out of range. Or if too much is added it will drop down below range. This can cause the lock out and the plant can't absorb nutrients right. Now If your ph is in range then it is the calcium. Would be the steps I would take.

Possible light stress?Any help would be much appreciated, so the leaves are looking with a yellow tinge , my thoughts were light stress as had lights on 24/7 on to high and to close I have since then back off on the power of the lights and move them further away from the plants and changed to 20/4.

Magnesium - Nutrient problemDo I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly.
The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1.
Has anyone the same problem?
Thanks!

Leave color normal?? [First timer]I am not sure about the color of the leaves if they look normal? The baby leaf seems to be turning a bit yellow. The rest of the leaves seem to be a bit discolored as you can see in the pictures but mainly green though. Is this alright or am I doing something wrong here?![[Beginner] First time growing ever](https://bucket.growdiaries.com/static/post/photo/88461/4159883_2331dae3699a0880c88dec9307405b8e_m.jpg)

3 week old Skittles plantThis is one of my skittles plants I'm growing right now. One of the leaves on her started getting lighter spots near the veins. It is only a little right now but I am wondering if there could be an issue that I could solve before it gets worse.

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH

Update on previous deficiency questionUpdate on previous deficiency question
The leaves got worse, its still only a few so not too bad. After doing some research i think it could be a Manganese, magnesium and/or Sulphur shortage.
I fed some liquid calmag a day ago. I plan to use epsom salt if there is no change

A few of the leaves started to get yellow spots along the veins. I was pretty sure it was nitrogen deficiency so I upped the nutes a little. Over the next day or so, 2-3 different leaves started to curl down at the tip. Is this too much nitrogen?Week 5
