Hello pls Help Got Pics.......

These plants are being top fed hydroponics ,

Using Gh Lucas Formula

Into flower for a week now

Started out with clones

Ph was when i took pic and it was at 4.7

So my question is is this a ph problem or a defency the reason why leaves are curling under?

Your PH is too low. I bet thats why your leaves are curling. PH imbalance will CAUSE nute decencies actually. I think for soiless mediums you want a PH of about 5.5...someone please correct me if I am wrong.

U r Right but over the weekend was gone and nute diped real low so i think that is what happened, but thank u for ur speedy response!!!!

Yeah with ur ph that low ur nutes are locked out.I've seen healthy plants in hydro with ph ranging from 5.5 up to 6.5,they seem to have been doing ggod up till now.What has your ph been running at? If ur ph gradually fluctuates thats normal.constant fast fluctuations and u have problems.
