Hey Fat; I have to say that at this point we are still dealing blind, and that ADDS more guest work in. But here is how you'll determine your next move. Scenario; If you flushed them 1day and the next day you notice the leaves are looking happy but the very next day the leaves dont look so happy and are starting to curl again, then we KNOW for a fact that soil has replenished its high-EC potency.
But If you've flushed them and the leaves perked up the next day and then was perky the next morning too, this says to me...them hoe's eatin!! and whatever that Soil's runnoff EC is...THATS what you feed them at! , I would start giving them .5EC Mixture on next feeding, I will say tsp=teaspoon sometimes AND I will say Tblsp=Tablespoon.(get yourself the right measuring device, AND KNOW THE DIFFERENCE.)
Ppl say they grow in soil all the time with no measuring devices; Thats good for them, but in YOUR case UNTIL you can accurately Leafread, Dont fall for that Blind growing fallacy. (what most growers wont tell you is the Fail's they had BEFORE they were able to Blindgrow. One guy said he think he had dumb luck his first grow..cuz things went fine...then his second grow things went AWAL....and you could tell by his post he was so stressed out. The true test of a grower is what he is able to do when things DONT go right. Always keep a mindset of & I will start this, I will figure it out, and I will finish this;
Somedays I go and sit with my plants and as myself questions like WHY THE F--- arent my plants growing faster, what could I be doing wrong, what could I do better, and this gets me in a process of thinkin that improves my grow everytime. Sometimes i notice things about them just from sitting with them, they talk to you if you listen.
Now back to the task at hand. I would first do 3tsp of Bigbloom and 1ml of Calmag+...put them into 1 gallon of RO water, this would give you a really low EC of .5 But thats cool cause right now we wanna get ya girls eating which these plants are more than adequate to handle that. and pour only enough to see runoff of this mixture. (We choosethat mixture becase BigBloom on a basic level is fast acting when it comes to leaves responding to it, and I can go into more details but that stuff aint important right now, But in the case of the 1ml of Calmag+ we use the Calmag+ because in addition to its 2-0-0 of Nitrogen, it also has Trace minerals in it too! which is what your plants need Remember that in some cases if you only pour enough Nutes in the pot to moisten the pot and not have runoff some times the .EC can become accumulative meaning if you have a .7EC runnoff of soil in your pot but you go and add a .5EC but you dont pour enough of it to get a run off, then you are likely to get an accumulative .EC of .9 - 1.0 thats not what we wont. This is a mistake that I'm sure alot of ppl make and in a case like that, Unless you're a good leaf reader, you wont know you've given your plants too much nutes until the following day when Lights comeback own if they arent perky YOU KNOW they now need to get a flush. MORE IMPORTANTLY THAN ANYTHING MY FRIEND. is YOU NEED SOME TYPE OF ppm or EC meter. otherwise all these flushes could seem insane specially if you dont know what your NEW EC is after a flush or if we dont know what our Base ph is for the water, that could ruin things too.
