Without both supplied at the same time, that growth surge can trigger a secondary deficiency. The micronised gypsum and Kieserite keep pace with the nitrogen response.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ab-faq7\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ab-faq7\"\u003eCan I use All-Purpose Booster on houseplants?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eYes. The solution format means no granules on the surface, no odour, and no residue. Use the lower rate (¼ teaspoon per litre) every 2–4 weeks during the growing season, and reduce or stop over winter.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ab-faq8\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ab-faq8\"\u003eWhen should I switch to Bloom Booster instead?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eAt first flower. Once a fruiting or flowering plant sets its first bud, its nutrient priority shifts from nitrogen-driven leaf growth to the phosphorus and potassium that drive flowering and fruit. Bloom Booster 2-10-5 is formulated for that phase.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ab-faq9\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ab-faq9\"\u003eIs it a replacement for a bottled liquid fertiliser?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eIt does the same job more efficiently. Bottled liquid fertilisers are typically 85–95% water by weight, so you're paying to ship water and a plastic bottle.

The amino acid nitrogen is gentler than a synthetic soluble source, and the balanced calcium and magnesium reduce osmotic stress.
