BROWN SPOTS ON LEAVES FROM NUTE BURN OR DEFICIENCY?
stonedkoalastarted grow question 4y ago
12/7 noticed leaf curl & yellow tips. Thought she had Nute Burn so 12/8 flushed her in plain water + hydroguard ~120 ppm. 12/12 did half the amount of nutes I would minus calmag. Brown spots appeared on 12/14 so I switched her to full nutes + calmag, ~500 ppm. ~45%RH @ 76 degrees

Looks like deficiency, but can also be too much light, check your ppfd and give it a day or two and see how she responds from the feeding you just gave her, Good Luck!

help in Hydro RDWC/DWCHello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds
They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?

Clawing leavesHey guys, I found out about Growdiaries a few weeks ago and decided to subscribe to track my grow and look for tips. Currently my plant is suffering from The Claw, what should I do? She seems to be a little burnt by the nutes. I'm currently watering her just with plain water.

Drooping leaves towards top of floweringMy Jack Herer Leaves are drooping towards the top of the flowering area.
Not sure what this is?
Over or under watering? Light stress?
Temps are 27c and 52%H so nothing out of the the ordinary
pH is always in the middle 6 area.,.

Purple stems-curling tips leaves point downGuys the sides stems seem really purple!even the central stem..
Why? magnesium deficiency?or genetics?
And that leaves tip pointed down; they are a problem..
Maybe N deficiency?(due the early preflowering for the wrong light cycle) Thanks :)

Leave Tips Yellow and Brown on New GrowthThe leave tips of my plants turned yellow and burnt after i gave them a bottled nutrient feed (organic). Unfortunately i failed to measure the PH of the Water (it was probably to high). This was one Week ago and the New Growth still show signs that something is wrong.

Wilting and yellowing leaves after vinegar water solutionI sprayed a mixture of 1/4 spirit vinegar + 3/4 water under the leaves to get rid of aphids (which may or may not have been the problem) earlier today. Now checking on her, I see yellowing of several leaves and wilting of others, which has me worried... normal, or a problem? 😳
