Organomananswered grow question 3 years ago

I would suggest going back and giving her a half strength dose of "grow" nutrients every second feed for a couple of weeks, this should restore some health, she is suffering with a nitrogen deficiency and this can not be cured with cal/mag. This yellowing problem/nitrogen deficiency is common amongst people who switch to straight bloom nutrients too early, cannabis still needs adequate nitrogen during the first few weeks of flower development. Hope this helps, Organoman.

Too much calmag on a regular basis can interact with your P and M uptake and cause dual deficiencies. Looks like yellowing started bottom up which typifies N def. How much are you watering per 24hrs? Plant that size would probably need .5-1L a day but I would try it 1.5L every 2-3 days.

Hello my friend. Looks like you got some PH issues causing lockout mixed with some nutrient burn. I would flush the ladies and cut the nutrients back a bit. How many ppms are you running them and what PH are you giving them? Also please elaborate on soil make up.

Yellow blemishes 1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas. Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.
