Bottom leafs getting dry
dotgrowstarted grow question 4 years ago
The last two pictures show some sights of deficiency after getting a little bit dry before repotting. Any recommendations: should I do something? I will definitely use some ph-down and water with 6.0 to 6.5 ph to help the microorganism get going :)

Hmmm it looks to me like some kind of Nutrient lock out or toxicity has she stopped growing ? if so this is most likely the case though as the grower has stated that ph is high and could of caused that too I would advisee giving her a flush for a few days and then re evaluating after that :) Best of luck anyway my friend :)

Thanks guys! Lockout sounds plausible. Will flush and hope the best :)

Hi mate, looking at your diary your PH is way to high. It should be 6-6.5 at all times. Although soil is a great buffer and it is possible to water her with ph 5-8, anything over 7 or under 6 and you start to see nutrient uptake problems. The burnt leaves look like Mg deficiency. But can't be completely sure. That is usually the first to show up if you have nutrient lockout. I hope this helps, good luck and happy growing.

Strange Twisting LeavesI have a plant that's just over 3 weeks old, and since the first week or so, I noticed it has some leaves that grow with a "kink" or "twist." They all seem to have a small discolored spot on the edge of the leaf that eventually becomes the corner of the kink/twistLeaves. Edges burnt

A deficiency, a toxicity and a toxic-deficiency???Here's what I make of it (and PLEASE correct me where I am wrong!) :
The tips yellowing indicates, a nitrogen burn.
The burnt brown tip indicates, nitrogen burned to long 😂
The black spots indicate, a P or K issue (as the leaves are otherwise healthy green in color)a month ago

Yellow leaf edgesI have a couple plants that are about 5 weeks old, and one has started getting yellow edges around the leaves. I feed them with worm tea, kelp, and calmag every other week, but it's a light dose so I think this is a deficiency and not a toxicity.Leaves. Edges burnt
