Yellowing and spots on leafs

[RookieHaze]

What are the signs of these leafs? I feed them with nutrient every 2 days. They are in soil. I water everyday. Around 1.5L they also have some burned tips
HR: 60%
Temp:30c

What are you growing in? Soil, coco? What nutes are you feeding, and are you adding Calmag? Looks like the very early stage of a calmag deficiency.

Growing in soil, I feed with micro, grow , bloom and calmag. But growing in soil, calmag nutrients is not a must. But I add it in the mix still. But calmag deficiency was my first thought aswell

Watering with nutes every other day may also be contributing. Are the nutes organic or synthetic? If synthetic you may have a salt build up that’s locking out some nutes. The other possibility is that you’re overwatering and that’s causing the brown leaf tips.

I know it's hard, but just get it in your system:

Feeding = Once a week.

Also: You push your lights first, stabilize your environment, THEN push the nutes.

I need a PH-meter for sure! But I noticed, its only yellowing on the upper leaves. The lower bud sites seems to be fine.

This might help you over time with undestanding what your plant is doin and why.
(Not if ure overfeeding all the time tho, then deficiencies are a result of nutrient lockout rather than having not enough.)

From that chart it looks like a potasium def. Could be lock out or salt buildup preventing. What are your PPMs? Run off and feed Ph?
