Warlock and Wonderwoman having problems (pics)

They are like 16-18 days old. Im not completely sure. I haven't kept track as well as I should of. Room temps are no higher then 85 degrees F no lower then 76. They did well with ph water 5.8 and PPM 300 for 2 weeks. Then the problem occurred.

Anyways day before yesterday I noticed that both plants were having problems. The leaves on warlock started to develop dark brown almost black splotches and surrounding it turned yellow.

The wonder womans leaves turned leathery with almost latex like look and feel to it. Then they curled and dried completely out.

Well I thought it was a nute deficiency so bumped up the nutes up to 480-500ppm. The next day the plants looked even more stressed and i felt they werent responding well to the res change. So today I changed the water back down to 300ppm.

Anyone know whats going on here?

Anyone at all?

Looks kinda like you nute burned them when you added more. Im not really an expert on hydro growing. But looks kinda like you had a cal/mag problem maybe since your ph seemed to be in check. Or, maybe like you said, the resevoir cleaning stressed them a little, and you made it worse by uping the nutes.

Well they started these problems before i changed res. When i seen them having a problem thats when i first changed water rez.

Im just letting them chill for awhile see how they respond to what I did today.

it says the twisting leaves come from ph lockout and the top one is more than likley nutrient burn. i dont know much about hydroponics though im a soil person.

They didnt respond well to the 300ppm nute dose so i bumped them both up to 480ppm lets see what happens...
