Dropping Plants and Yellowing Tops

[mrwallstreet1]

Hello I have been having issues with my plants dropping.I recently switched over from veg to flower. While in veg everything was nice and perfect with all leaves reaching for the light and standing high. Now I am in week 2 of flower and all my plants have been dropping and all tops turning yellow. At first the temperature was really low at nights reaching in the low 50s which I thought might have been the problem. I since then raised the temperature where I am 58 degrees -65 at night and 70-75 during the day when the lights are on. My PH is at 5.8-6.0. I am in rock well and use the EBB system where I flood them once - 2 a day but mainly once. I looked under the block and all the roots look good with new white ones coming out. Growth seems to have stopped and no signs of any bugs at I did a root aphid wash in veg and a bug bomb week 4 of veg before kicking over. Any help would be greatly appreciated.

Ebb and flow needs more flood/drain cycles as the plants get bigger. Try four times per day for the next three days.

Do you think it looks like nutrient lock?

I think they looked starved from not feeding enough.

I agree with BeanTownFan420. The plants look starved, and dying of thirst.
