You say the last one looks like cal mag def but the others are nute burn? I'm pretty sure the last one is having the same problems as the others only not as bad yet, so does that mean that its cal mag or nute burn you think? From what i have found out i thought it was cal mag def. also. But i dont want to add cal mag and then in turn add to the problem if it is nute burn. Should i try flushing them or adding cal mag then?

flush, and try adding some cal/mag in one plant and see how it looks in a day or 2.By then you should tell if the cal/mag worked or not.

I second that opinion.

I second that opinion.

ok That sounds like a good plan, I'll get right on it, thanks for the input it is much appreciated

[max budz]

If i flush then add cal mag, should i add my other nutes also? Cause wont they get washed out with the flush?

[209 Cali C.G]

I did^, but I flush really, really good!and went 1/2 strength on mine.

For every gallon of soil, you flush with three gallons of water

since you added amendments to your soil mix, you don't even need to feed unless the plant begins to show you some sort of deficiency. The EWC and guanos should have enough food to support your microbes for a while

I'd do a flush, wait a day or so for things to stabilise, . .give the roots time to dry off abit then do a magnesium/calcium feed, or you may end up with waterlogged roots . . .and I doubt thats much fun
