If that's an LED light, which it looks like, can you take pics with normal light? LED can make plants look weird to begin with. Sometimes my girls look dark green under my full-spectrum LED, but under a normal LED or normal light they're the proper shade of green.
Keep up your night time ....even day time temps...you aint the only led grower to have a cooler grow room now that many are moving to leds ,,,little heat?
Its been topped 4 times for a total of 16 tops plus side branches. Shes going to have all the room she needs very shortly as shes going outside.What V was attempting to say is that he thinks the purple in your stem's is from the temp drop at night. And/or, you don't have a problem as that is "normal"....
Lets see here,,,,mum,mum,mum.....about 64 at night and 76 at day time......Yeah that could be the thing doing it alright.....
But really....It's nothing to worry about!!!
I might not have done as much topping as you (as shown in pic. 1,,you topped it and got only a single shoot, so what was the purpose there?) as I might lean more towards the plant is stressing to catch up from all the topping, being in that small a pot for the plant size......So ,, I would up pot to the next size at least with that one.....
But again, the purple stems are not really a problem.....Let the plant spread some feet and unstress awhile.
Doc
Not at all, leaves are green as can be looking healthy. Only the new growth is lime green but thats normalAny other problems or deficiencies showing?
Yellowing leaves?
The read coloring in the stems is anthocyanin, or common food coloring or (K) bottom line, growing your plant involves 3 simple steps supply light, heat and nute in (N), (P) and (K) if you can't keep up the heat then you are gonna loose one of those three, in this case its always(K) first, seen by the abundance of red in the stemThis is a MH 1000w blue bulb.
Fan leaves are healthy and new growth is good. temps at night is 18 day time 24ish
grow a & b connoisseur from advanced nutes, cal-mag plus atmWhat are you currently giving them for nutes?
Okay sounds GooD thanks guysNo matter the size of the plant......The nutrient mix remains the same.....You see, your going to give a larger plant more mix then you would as a small one...understand?
Ssshhh, you should whisper when you say AN around here......
For the most part V is correct! I might not worry about the temps yet...and 80 is the high max with out Gassing Co2.......your present temps are fine ,,,,, I'll bet the swing will increase some when outside anyway......don't add K to attempt to correct it.....It's fine the way it is.
