Nutrient burn, magnesium def, light burn? Leaf tip yellowing but not turning brown/curling

Tubington9started grow question 5y ago

4 week since planted autoflower, both started getting this at the same time. First time running autos, grown in FF Happy Frog soil. Soil was used for 3 weeks in a different grow so nutrients may be needed. Light burn, mag deficiency? Have only used ph 6.2-6.5 water, no nutrients.

Lacking in nutrients mate. The soil nutrition will be depleted. So 1st feed with nutes use week 5 or 6 of there schedule at half strength, see how they respond, then next feed push 3/4 strength see how they respond then water for next feed and repeat.

Discoloration continues Pattern seems to be progressing. Brewed molassas tea with alfalfa, kelp and worm castings. Spots worsened so I treated with CalMag last night. Thought I would post to see if I could get your thoughts.

Leaf damage/discolouration The Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four

Warum werden die Blätter auf einmal so schnell gelb und welk?Hey, my Hawaiian Runtz is at the end of week 4 of flowering. I water every 4-5 days with 2-2.5 liters of water and a pH value of 6.5, always pretty consistent with Terra aquatics pH drops, so pH errors should be ruled out. Temps during the day are around 28 and at night 26 degrees Celsius. What’s wrong?

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.
