Plant Growth

Hey! so the last time i blogged was on the 30th
I have looked back on my last blog and have no idea what i was doing- my measurements have really confused me and make no sense so heres some correction:
the overwatered plant: 7 cm
Normal: 8 cm
Underwatered: 10 cm
since then:

on the 31st:
the overwatered plant (O) was: 8cm
normal was: 9.5 cm
and the underwatered was also 9.5 cm
however it now seems like the underwatered plant is starting to get effected. It is drooping more and the leaves are starting to scrunch up slightly- kind of drying up and it is not as green- it looks sick. Also some dieback is starting to occur- a healthy plant should receive very very little to none at all as die back is a sign something is wrong. The overwatered plant has currently got the most ie back but it is still minor on the edge of some leaves. The underwatered also has some too although slightly less.
for the 2nd batch:
Overwatered plant height: 4cm
Normal: 5.5 cm
Underwatered: 5 cm
The normal plant is growing the fastest just like the 1st experiment where it was right up there but this time the underwatered plant grew faster than the first time and the overwatered plant is growing at a slower rate.

On the 1st of june:
the overwatered plant was: 8 cm
the normal plant also remained at 9.5 cm
however the underwater plant had now drooped to 8 cm. It has not shrunk more so it is drooping and hence not as tall. Up until now, the length of the stems had been the same as the plants height as all plants were standing upright. But now- while the stem length is still 9.5 cm, its height has decreased. This indicates that the plants health is deteriorating as a healthy plant should have a strong stem that supports it allowing it to stand upright. the leaves of this plant are dieing and scrunching up more so as well. they are appearing more dried out then ever and the soil in this plant is very dry. The Underwatered plant now has the most dieback, followed by the overwatered plant and then last with little is the normal plant.

Batch 2 plant height:
Overwatered: 6cm
normal: 8 cm
Underwatered: 7cm

on the 2nd of June:
the plant heights of the first batch have remanined the same.

The 2nd batch:
Overwatered plant: 6 cm
Normal: 9cm
Underwatered: 8 cm
