hey guys,
Im on my 2nd grow, the first one was better than expected,
and now im having some new problems that i didnt encounter the first time around:

Im growing in a 60*60*160cm grow tent
first 3 weeks under 65W CFL, from week3 to the end - 250HPS
4 plants, soil, strains: White widdow*2, Somango, Blue mistyc (all from Royal queen Amsterdam)
avrage temp: 23celcius, 40%-50% humidity

MY PROBLEMS:
1.its day 28 and they are midgets! last grow they were twice the size on day 28
see pics below from this grow and the one before on day 28.
what can cause this?

2.they are very yellow, small black spots appear, doesnt look like any deficiency i know
i`m using nutes: SENSIGROW A+B, B52, Revive, Rootjuice
small amounts from all of them
what can cause this?

3.I will finish growing them in a 7 litter plants. now they are on a 0.5 litter, should i already transplant?

4.Is topping and LST recomended at this stage? they dont look very healthy....

**The gear is exactly as i used on my first grow, the diffrences i can think of:
Its winter now and much more dry. average temp on last grow(during summer) was 28-30, humidity 60-70%
different strains - last grow was Northern lights and Skunk#1

GUYS THANKS SO MUCH!!! KEEP ON BLAZIN :thanks:

Could be root bound. Every strain has different root systems, and I think I have heard that WW has a tendency to overgrow its pot quickly.

What is your watering schedule like? If it isn't as hot/humid as your last grow, you might be over watering them

They don't look ready to FIM, of LST imo. If they are stressed, you don't want to stress them even more.
 
i water about triple as long as i did in the summer.
in the summer i watered every 2-3 days, and now 8-9 days
only when the soil is dry
so should i already transplant?
