Deficiency in Coco (picture)

[InNvBoarder]

House and gardens doesn't have a "calmag" supplement. Ive run the h+g for years and there are a few additives youll need if you want that magnesium defficys to go away. Sweet or some other carb, maybe humbolt honey? I also recommend Botanicares cal-mag!! A must ( epically if your in coco) I haven't read to see what medium your in.Some kind of calcium/mag supplement is a must! Over feeding isn't the case it sounds like. Most likely your missing a supplement. Another good way to make sure your getting allyour nutes into your plants is to let your ph range from 5.6-5.9 from time to time. Some nutes don't absorb as well at say 5.6. They may absorb better at say 5.9! Your "pk" boost that is coming wont absorb as well at 5.6 as it would at 5.9/6. Good luck and read into these problem and successes on the infirmary. Sick plants thread is the best there is for info !

House and Garden nitrogen boost is the magnesium supplement. The base already has plenty of calcium.

H&G has plenty of both in the base formula.
A high EC slows water evaporation and diminishes Mg availability.
Adding more magnesium to a system when there is a lock-out will only make the situation worse.
A nitrogen toxicity will also slow absorption and cause stretching and those small flowers at 5weeks.

Now for having too much nitrogen in your growing mediums or soil. The plant will have like an overall DARK green look and have delayed maturity. Due to Nitrogen being involved in vegetative growth, too much nitrogen will result in tall plants with weak stems. New growth will be very lively and plant transpiration will be high, but not always. Nitrogen toxicity can be seen when there are very very dry conditions almost as if there was a drought, which may show a burning effect. If you give your plants ammonium based nutrients they may show NH4+ toxicity, which will show a smaller plant growth and lesions that occur on stems and roots, leaf margins that will roll downward. Also the big fan leaves will have “the claw” look. The tips will point down but the leaves will stay up as if when you bend your fingers downwards. Leaves can be twisted when growing… mainly new growths. Roots will be under developed along with the slowing of flowering. Yields will be decreased because too much nitrogen in early stages of flowering slows down bud growth. Water uptake is slowing down from the vascular breakdown of the plants as well. Too much potassium and nitrogen will lock out calcium as well.

Magnesium is one of the easiest deficiencies to tell… the green veins along with the yellowness of the entire surrounding leaf is a dead giveaway, but sometimes that’s not always the case here. In case you have one of those where it doesn't show the green veins, sometimes leaf tips and edges may discolour and curl upward. The growing tips can turn lime green when the deficiency progresses to the top of the plant. The edges will feel like dry and crispy and usually affects the lower leaves in younger plants, then will affect the middle to upper half when it gets older, but It can also happen on older leaves as well. The deficiency will start at the tip then will take over the entire outer left and right sides of the leaves. The inner part will be yellow and or brownish in colour, followed by leaves falling without withering. The tips can also twist and turn as well as curving upwards as if you curl your tongues.

Excessive levels of magnesium in your plants will exhibit a buildup of toxic salts that will kill the leaves and lock out other nutrients like Calcium (Ca). Mg can get locked out by having too much Calcium, Chlorine or ammonium in your soil/water.
One of the worst problems a person can have is a magnesium def caused by a pH lockout. By giving it more magnesium to cure the problem when you are thinking you are doing good, but actually you are doing more harm then good. When the plants can’t take in a nutrient because of the pH being off for that element, the plant will not absorb it but it will be in the soil… therefore causing a buildup. A buildup will be noticed by the outer parts of the plant becoming whitish and or a yellowish color. The tips and part way in on the inner leaves will die and feel like glass. Parts affected by Magnesium deficiency are: space between the veins (Interveinal) of older leaves; may begin around interior perimeter of leaf.

Yeah don't use their schedule its way to strong



Just cut back and you will be fine.


Everything looks pretty good besides the excess nitogen/nutes
