yellow/brown spots on lower leaves
AlpAge_Cinostarted grow question a year ago
Hi, 2 of 8 got yellow/brown spots on lower leaves. I've watered them once a week and add calmag, pH=6,2 following b.a.c. instructions. Last watering, i forgot calmag so I did a second watering 5 days later with calmag. What could be the problem ?

They just need more food. Looks more like phosphorus and potassium deficiency starting, the burn straight tips say more then just a magnesium deficiency

Calcium deficiency.
Over watering could also cause this.
Even if only Watered once, it could cause the problem if the soil don't have enough perlite or vermiculite..
I would add a little more calmag in your next feeding. Goodluck broskie

What causes hydro Ph fluctuations early in the grow?What causes dramatic ph fluctuations in hydro conditions so early in the grow, and how can I mitigate it? I have hard water, so I know that’s part of the issue (I tried to install a RO system recently and failed miserably). Other than frequent testing & additives, what can I do?

Brown spots on bud site leaves?!halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition?
I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Phosphorus deficiency? Week 5 of floweringIs this a phosphorus deficiency? I originally saw orange and brown spots form on other leaves, but now I'm seeing blackish/purple spots. I've been having soil pH issues with this one, so may need a proper flush. Temps have also been low the past few days (60-65 but as low as 56)
