Tacoing then dropped?

My guess is heat stress...but that's just a guess. They generally droop when they are too dry or after they've just been watered. But it all depends on what the temps are in your grow space. Even fluorescent lighting can create enough heat in a small space to damage your plants. But when you have issues, you need to provide as much info about how you grow your plants as possible along with good clear pics of what you're talking about and always try to give us pics of the whole plant too. At some point in the future, if you want to grow a more lush and healthy plant, you'll need to upgrade your lighting. The stronger, better quality lighting you have over your plants in both veg and flower, the better the harvest and the better quality the weed you grow. CFLs will take a plant from veg through flower, but you get nowhere near what the plant is capable of actually producing when you have less light than the plant needs to do it's best. You need to get yourself a pH tester and start managing the pH of the water/feed you give your plant. Extended water/feeding out of pH range will eventually lock up the roots of your plant and it can't take in nutrition. And why do you have the DME or whatever that is covering the top of your plant? Have you been battling bugs or something like that? During veg, they need good soil, proper watering only when they need watering with pH adjusted water, good light and for the grower to just leave them alone...assuming the conditions are good in your grow space. But if you're growing in a really small space, heat is almost always going to be an issue. But if it's not the heat, make sure you're only watering when it's necessary. Overwatering is the biggest killer of plants by new growers. TWW
