hallo everyone, we got some Early Skunk plants and since 1 week we are very worried. We are growing them outdoor in The Netherlands. Beside they dind't start flowering yet (weather condition i guess), since one week they got black spots and yellow leaves. They are almost reaching the top leaves. we thought about a nutrient deficency. We added compost once when they were 1 month old and once during the transplant. on May we add and Organic Pellet (N-p-k 3-5-5)in the first week of July. Therefore we don't think that is a problem of over fertilizing but nutrient shortage. However we would like to know if is possible to be any kind of fungi or mould. Today we bought one chemical fertilizer 5 6 7 + micronutrients ( some of them are chelate) in order to solve the problem. Do you think it makes sense? In how long we can see some reaction? See the pics to better understand the situation. we look forward to hear some answers... Thanks DD
the same exact thing is happening with my plants. its been going on for about 2 weeks and it progresses more everyday until the leaves turn completly brown, droop and curl under sorta like a straw. and their not crispy but really soft.i wish i knew the problem. im thinking it might be a ph problem so im going out to get a tester to find out.
The all-over yellowing of certain leaves is from Nitrogen deficiency. The necrosis could be caused by Phosphorus & Calcium deficiencies. Ca-def can cause tiny, mildly necrotic spots. When combined with P-def, the little spots grow, become more necrotic and if left unchecked will cover the leaves, often causing more damage & yellowing towards the leaf tips. You'll want to check the soil pH before feeding, as the wrong pH can cause or at least exacerbate deficiencies. Be sure to use an accurate method. If nutrients are being locked out by incorrect pH then that must be corrected before the plants can make use of the food you give them. Welcome to Grasscity
Thanks guys. we have transplanted the plants in bigger pots following the advise of a friend of us. we will check Ph and add nutrients. We'll let you know. thanks
