Well Im 99% sure the problem with our eldest sweet tooth is magnesium deficiency which is bound to effect our other plants also soon, I did add dolomite lime to the soil however I did not crush it so if you ever get dolomite lime remember to crush it up really good if its in pebbles, I think the grow big was helping this from becoming a real problem because grow big contains mag, almost instantly after switching to Tiger Bloom this problem showed up, PH seems to be fine I have checked and rechecked runoff and I always check solution but I could go for another runoff test this morning....
It has become quite obviously a mag problem, starting on the middle-aged fan leaves and then working its way to the new leaves it progressed in only about 72 hours to where it is quite evident on the entire plant (our eldest sweet tooth).....So my mission for today is to go to the hydro store for some cal-mag...If I do not have the time to do this today I will be using 2tblsp espon salt in a gallon of water and feeding her, likely maybe even crushing up some dolomite lime and sprinkling it on the top of the soil..Keep in mind I have read this to be quite common when you use distilled or R/O water and we are using distilled.
These plants sure could produce a rocky yield with all these problems I have had, but none the less its a solid first grow, and so far its been testing on the plants as I dial in the entire setup, hopefully future generation will not suffer this much lol, I have learned a lot so far and I hope you guys have also, I hope we can work thru this problem just like the others.
The start of it as photographed earlier, it is much worse now, however, much more obvious the problem is mag at this point, this is a middle-aged fan leaf, my research tells me this is the location mag deficiency typicaly starts to show:
