Double grape seems to be the strongest plant of the four I'm growing . I'm sure I've made some rookie mistake already and I know my ph has been on the higher end for the medium I'm using ( promix hp) , but I've gotten a bottle of ph down and can now remedy the situation . Also we have had a fair bit of rain here so I'll be using that to water on the next while , see if the unchlorinated water makes a difference
Looking through the previous few weeks it looks like you were under feeding a bit. Another possibility is the pots may be a bit too wet preventing the roots from nutrient uptake. Unusual for soil less but it happens. You can see a bit of leaf drooping and a little curl on the tips. Were all guilty of it at times try to let them dry out a bit more than usual before your next watering. Your plants are big enough to water till the point of runoff. Takes a bit of getting use to but feeling the weight of the pot before and after watering helps out. Another possibility is you need to add some beneficial microbes to your pots. If your using tap water that contains chlorine try to leave it out aerate it with an air stone too much chlorine can block nitrogen absorption and kill beneficial bacteria.
@Philindicus, I think I've figured it out. I moved my hydrometer up higher in the tent and its reading 30C ! I have a fan blowing over top of the girls but that's too hot . I bought another booster fan to push air into the tent from outside
@Pisstank85,If your using LED lights invest in a PAR meter It will help you get the right distance from your plants during the different growing stages. I helped me out a lot.
@Philindicus, funny you say that I just got a bottle of Plant Success Orca today . I gave them a dose tonight with the watering . I'm finding since I added my second light and lower humidity the plants are drying out quite quick , 3 days and they are bone dry , the double grape and ghost toof particularly seem to soak up the water quick . I'm thinking of adding another fan to keep the heat down ..it sits between 26-28 which is probably high
Your buds look perfect. I'd leave the light where it is. If you move the light too close you risk burning the buds. Also terpenes and THC don't like high heat and will burn off. As long as your temps are under 80 F your good.
