My first dwc and having issues please help

OK so this is my first run on DWC and Im having an issue that Ive had before in soil and couldnt stop it in soil either. Can you please tell me whats up with these leaves and what to do

so a little background they are Shiskaberry 40 days into flower, ph 5.7 and ppm 1200.
i did go in there the other day and the PH was down to around 4.5 (first time thats happened with DWC)
any other info needed ask


and heres them in the flower room kind hard to tell whats going on with them in there due to HPS

What are your nutes?

I use a 3 part micro, growth and Bloom.

I think many people leave out the micro part and end up with problems, much like you have.

I use the Dutch Master Gold Series Two part bloom, with add .27, silica, and Zone, as well as Gravity and Purple Max to finish up flowering.

I emailed Dutch Master awhile back and they said I dont need Cal Mag because of add .27 and silica.

I use Holland Seceret for my DWC, which includes micro.

You're either too hot (back off to 1000 ppm) or your lacking the micro nutes, I would do both..

FWIW I had this same problem with my solies and cal mag+ fix it right up.

I did a quick look at the DM nutes you are using.

I would ask the nice folks at DM where your plants are getting their micro nutes form, cause I sure don't see it. add .27 and the silica seem to be nute enhancers that help in the nute uptake.

Get some cal mag.

Great thanks for your input Ill try that and see if it works. + repto you for the quickness

You are welcome.

I have experienced this and I would be suprised if the cal mag and lowering the ppm does not fix you right up.

good luck.
