Babies doesn’t show any pistols

Using ph perfect nutes in hydro isnt the best. Make sure your monitoring your ph and ec levels. Recommend Dutch nutrient formula, DNF, It was made just for hydro. Wont need to add anything extra as long as you keep your water cool. Max dissolved oxygen water can hold is between 62 to 68°, that is were your plants go from just growing to very fast vigorous growth that will produce buds the size of a 2 liter bottle of pop. Also with cool water you dont need to add anything to keep your roots healthy, so it can save you a lot of cash as well. Cheers friend

If you have calyxes and not pistils, you may have a male. Pictures would really help. Stress can make your babies go into flower early or late, especially with autos, so I couldn't say if it's good or bad. I would lean towards it being good if they are bigger than normal before flower. If they are in bloom, however, I'm guessing you're seeing some kind of flower but no pistils, so my money would be on you having a male.

Hey there Michael Man, in hydroponics the (relative) ratio of nutrients is more important than in soil because the soil will buffer out some of that sensitivity with naturally occuring nutrients which hydro doesnt do. So ased on your pictures i can see purple stems which in your case is due to a lack of calmag as well as a lack of a chelation agent to break down the nutrients. in hydro you always kind of need three things, NPK, calmag, and a chelation agent. So far you're using only NPK so it's leading to this kind of growth. You'll want to add cal mag as well as something to break down the nutrients such as beneficial bacteria like hydroguard or H202 at 0.3% , humic and fluvic acid, something like that. Often chelation agents are called "flower boosters" so that's a clue. Fix this and the plants will bounce back meaner than ever. Hope this helps ! 🚀

Ive been looking into your Diary, and they soon will show some Preflower// flowers

Dear MichaelMan, On top of the @Mr_Motalohav's response, you can also check whether you have any light leakages in your grow room. If you can, please try to sit in your room for 2-3 minutes (until your eyes adjust to darkness) and see if there are any leakages which might prevent initite flowering. Hope this helps, Y

Hey! Some plants just take longer than others to show pistils but three weeks is quite some time. There’s no picture so I can’t say exactly... Couple things that could de wrong.. is the environment good for flowering? 12/12 light, ph.. all that If there’s no sign on pistils be ware of male reproductive signs. Little pollen sacs where the pistils show be.. Hope this helped Good and happy Growing.
