Hey just to drop another little note. You can't flush a plant. You can only flush a toilet. There are mobile nutrients Nitrate being the most mobile which can be leeched from the media matrix by water, the harshest chemical solvent on the planet [ think about how many things are soluble in water over such a various array of temperatures... ]
Feeding plants is like making a sauce , you get your seasonings [fertilizer] together and add them to your base [water] in certain proportions for each dish...You don't dump hella salt in to the sauce and then dilute it out and hope that you added enough water to balance the salt you poured in the sauce to make the taste right..You need to grow the same strains enough times with the same nutrient program enough times to see how long to keep whatever variety you want to crop pushing as hard as it can genetically go...
For example...The D.O.G has been my bread and butter for the last 5 years..I've done it enough times to know that the nutrient matrix for the plant needs to have low nitrogen/calcium input or it will delay the flower set, the potassium , magnesium, sulfur , iron need to be kept high almost the entire time for the flower set to come on strong..
I see more and more people just following charts and buying products instead of just comparing labels, seeing that all these products are basically the same shit...All you need is a very good A/B , an enzyme , and a MAP/MPP/DAP additive..
I dare you guys to get a good A/B..my favorite is Super Nutrients Super Veg/Bloom if I'm going to use a 2 part ..Nitron A35 enzyme ... and some Super Natural Brand Bud Blaster..Rock the EC as follows : 1.0 for veg young plants to adults, 1.5 for the first 2 weeks of bloom A/B and enzyme only, at week 3 bring the EC to 1.75 by adding bud blaster back to 1.5 on A/B only with enzyme for week 4, week 5 bud blaster again week 6 EC 1.25 week 7 EC 1 , keep them on EC 1 for as many weeks as you need to continue the flower cycle, I go for 8 weeks...
Cannabis needs to absorb all the nutrients its whole life cycle in different ratios to complete its biological processes, in its young stages it needs a lot of nitro, cal, potassium, silica to set up a good branch / stem structure ..in early bloom it asks for the biggest hit of P to set up a very fat root zone and then barely wants any...in mid bloom it needs calcium, mag , sulfur, iron, nitro, potassium out the wazoo to make a thick dense bloom covered in a bunch of sticky smelly oil..in peak bloom the requirement for sulfur, potassium, iron, and magnesium rises even further as the flower goes in to ripening when much like an older person it stops needing to eat so much and if it isn't getting bombarded by the grower at the root zone will naturally finish its life cycle. Over feeding plants really fucks with them and over fed plant syndrome is something very common in marijuana cultivation today.
